@@shenlong7890 Apple usually supports the hardware for approx 5 years after the discontinuation of sale (refurbs don’t count) and the software a bit longer still, somewhere up to 6-8 years. I’d assume the M1 models see updates through 2027.

Senior systems analyst here, although I haven't looked at the specifics of the two devices relating to this, this is almost certainly going to be a battery related issue. Both of these motherboards will be expecting to be connected to a specific battery size and voltage that almost certainly differs between the two models. While they can in theory boot up with either battery, Apple will have most likely locked the power requirement to be within a very specific range and as such anything out of that will not power up.
most times apple even lock the display to work only with it's original MoBo... idk, I know touch Id and security things but why I shouldn't be able to boot an OS and at least try things like old macs
@killerhakie whilst the model may be the same from a certain perspective, there will be actual differences from a technical standpoint internally. It's also likely apple have serialised the parts, meaning if serial numbers do not match for certain components, it will not boot or work.

@@allthenamesrtook Yep. If you try to change a single chip on the motherboard, it will only stay at 5V instead of 20V and will not boot up.

Maybe voltage and ampere of the battery are different. Or the capacitors are different. The M2 has a slightly higher watt consumption with consistent battery lifetime to the m1
I just imagined an alternative universe where Apple offered upgrades, like say you can get your M1 Macbook upgraded to M2 for 500$ but when they introduce major feature revisions you have to do the full upgrade. Because as it stands most people will keep their Mac through maybe 2-4 model iterations before upgrading. The old boards could be refurbished or put into repaired laptops. That could actually be a way to capture a bit of revenue from users who won't spend 1200$+ for the next version. It's a win win

that's really weird. I haven't gotten my hands on any m2 machines yet but with the m1 you can get a bare logic board to boot with nothing but the charger plugged in (you can confirm it booted based on the current draw using a usb-c power meter). So you could've started disconnecting things from the board until it would boot. I agree it's most likely the keyboard/trackpad that was the issue, although I also wouldn't be surprised if they did something funny with the battery. Fantastic video and great idea overall, would love a follow-up where you try to find out the culprit
on iPhones they do tie the battery to the logic board with a battery serial number. if you don't go through an authorized apple repair you would loose the battery health monitoring features. Probably something similar.
@@ThatOneGuyGreggers thankfully so far I haven't seen any issues with battery replacement even on newer macbooks. my theory was more that they might've made some small unnecessary change to the battery and therefore given it a new part number, which the other board won't recognize and will therefore refuse to boot. Either way, I wouldn't be too surprised if it's just more Apple serialization BS as usual
Mutiple componets have their own ids, and i believe the massive amounts of differnt ids may have prevented it from booting too. (Display id, battery, etc.)
The boards probably check for matching hardware serials on different components. Apple is becoming an e-waste nightmare with how hard they have clamped down on their machines not being user serviceable.
This video was awesome. I loved the energy and genuine shock when the M2 board didn't boot. There are a few minor component differences and I am sure it was something with initial BIOS load validation or some such nonsense. Either way, extremely entertaining, cheers.
Did you place the screws back in before booting? Cause some laptops use screws to complete the circuits in logic board. Also other companies make sure their logic board works only with the original chassis. How? idk. I could very easily find out if i had such devices to play around with and time. I completely love disassembling laptops much more than desktops. Great work.
It looks like Apple has gone to tremendous lengths to make sure people can't just swap parts in these computers making people have to buy a new machine if a part fails or to have Apple fix it for a charge if out of warranty!
Your problem is, you want the thief to have your hardware. Now it doesn't make sense to steal a Mac or iPhone. Even to replace parts and that is great news.
Hey Luke. I've been following you for a while from the UK. I do repairs and tried the same thing in a customer's machine. It's actually possible to swap the board, but you must swap the trackpad in order to turn it on. The keyboard and other components are actually fine. I just thought to let you know. I love your videos on content. Keep up the good work.
I’m surprised it didn’t work considering that nearly the entire computer is on that logic board. Also if Apple were to offer an “upgrade” logic board it would still be very expensive since all of the core components are within that single board. It’s more like replacing the computer than “upgrading”.
I'm curious if you can add another 256 Gb module in the empty space and upgrade it to a 512 Gb. Would it be possible? maybe get it from another dead MacBook Pro.
Would run into the same problem various experimenters did with trying to swap the flash chip modules on the Mac Studio. Without reprogramming the controller itself with the parameters of the new storage layout, it will not function at all, or at best you'd still only be access the original amount of flash.
It is probably some parts pairing between the logic board and the 1. Display 2. keyboard 3. Trackpad 4. Battery BMS 5. Lid position sensor or some combination of these.
Ex-Genius here. 1. The screw you removed from the heat sink we call it "super screw" 2. The swap didn't work because you don't have access to System Configurator (not to be confused with Apple Configurator). System Configurator is only available through AST2 and must be run on all post 2018 macs that had the MLB replaced.
There are a few parts I may guess could be the culprit: screen, battery, keyboard, trackpad, maybe even the WiFi connection via the cables. I recently swapped the motherboards of two old Dell laptops for fun and it refused to display an image because of the screen. The issue was I had to fully drain the CMOS battery and then it would boot. I have no doubt Apple found any way possible to lock down the MacBooks from being upgraded/repaired.
Did you happen to try connecting the MacBooks to an external display to verify that there was no power and not just a simple case of no video signal to the displays?
Two options are either voltage or failure of some device. You can try to use the M2 power supply unit (then we will bypass the battery). But I think most likely the "Bios" of a Mac (of a specific generation) is able to work only with a narrow list of hardware - after all, they don't need more.
Foam cover over wi-fi antennas is so that if you squeeze / dent the bottom case in your school bag and generally mistreat it, the metal bottom case doesn't short on the wi-fi antenna's causing reduced reception. (I'd guess)
Mac OS generally works by doing a scan for expected hardware and checking it can make system calls to it before continuing boot. I’m guessing Apple has made each config SUPER specific. This is as opposed to previous Apple hardware. My 2015 iMac is is composed on 95% the same hardware as my late 2014 iMac. My guess is that the parts on each upgrade for M series macs has, at the very least, slightly different hardware ids My question remains “can this be hacked around?” Here is my experience, again with the iMacs I own. You can swap displays on these things, and they are “backwards compatibles” for RAM modules and other things. The only trick is because of that system call test issue, you can hit boot issues. But if you add hardware IDs to opencore (the boat loader for older macs that allows you to boot newer versions of Mac OS, as long as the OS itself supports your hardware. Example, 2012 and earlier macs recently got bumped down because Mac OS removed support for a specific codec that the intel chips of that era and before need to boot properly (something to do with graphics) so those won’t run. Anything newer will run fine, as long as you have reasonable expectations for your hardware. My Late 2015 is kind of just on the edge of not running Ventura all that well. But good enough for me ymmv, but anything newer than that is going to work fine.) My question is, once hackers get access to M1 in the same level as they have intel Macs, could the ID numbers for relevant parts in the old Mac and if that would facilitate the upgrade. Given the priorities of Apple Software, it would. It surprise me at all if the old system check method was still the exact way the new Macs worked.
Try swapping the battery’s as well. Apple serialized the batteries in their phones. It probably won’t work without the proper battery. Test it by unplugging the battery and connecting power to see if it turns on.
Potentially Apple may have done what they did to iPhones, and paired the logic board to the screen, so in the event the screen gets damaged, they have to use their magic proprietary software to get the logic board paired to the new screen in order to boot?
It may be that some of the connection points have different pin configurations from the M1 unit to the M2 unit. It would only need to take a few differences to prevent the M2 logic board from working in the M1 unit. Also additionally, the bios microcode might not allow such a change.
macs dont use bios, its the fact that its a different screen, trackpad, whatever assembly that stopped it. its called part out protection so no one, even if they have the mac, they cant steal your data.
Fyi there could be a voltage difference between the circuits in the m2 chip that could require either less or more power. The total reason could be the supply of voltage going to the main power board causing a voltage miscommunication that interferes with initializing the new m2 board. In addition there would be several components that are not compatible with the board just like any other laptop. Yes it may be apple but they want you to buy a new laptop instead of fixing your broken or current one. Usually when the system boots it does a system check to see if any components are compromised then boots once validation is complete. But if you didnt here the fans spin on startup thats because there is a voltage issue.
It could be that one of the reasons why you made the video, (and why we expected it to work) is because the Space Gray color of the macbook with the M1 is more beautiful than the computer with the M2, So, because you would buy a new one in space gray with m2, when you can move from m1 to m2?
Me suffering and worrying for fear of breaking the RAM clips in my dad’s 2011 ASUS and this guy opening and playing around with two laptops worth several thousands each 😂
If it is a different interface on the keyboard and trackpad, you could try not plugging in the zif ribbon cables for the keyboard and trackpad. Assuming you can still plug in the power button/fingerprint reader, the computer should boot up without any keyboard and trackpad connected, although you obviously would not be able to login unless you plugged in a usb keyboard. Do not respond to impostors of this channel who reply here. They will take all of your money. Be careful.
You have to consider which devices are security locked. I know on iPhones, that means the camera is locked to the motherboard so swapping the camera stops features from working for security reasons, so if its the same in the MacBook, then changing the touch ID and motherboard won't work, you'd have to extract the camera module and swap them over too. A bit like those people that swapped their Mac Studio modules and wondered why the Studio wouldn't boot.
I can tell you right now it’s not for security reasons, it’s so apple stops you from replacing and repairing your own phone. Apple just loves serializing parts of the iPhone to stop independent repair. For that matter I’m 100% sure that apple made it so the device won’t boot because there is some identifier in the hardware saying it belongs to m1 (like diff voltages within the hardware or different pin outs) or some serialization denying the possibility of booting if the parts don’t quite match.
I baby my M1 MacBook Air so hard. The couple times it’s left my bedroom it’s been in a sleeve and I kept it in the passenger seat of my car lol. I’d never be able to take the bottom plate off unless it was broken and that was my only option… even then I’d probably be weary and do it in a room with zero dust/wind and spend like 8 hours doing it as delicate as possible. I don’t even have a smart TV anymore.. gave my nice Samsung 4K to my nieces, this MacBook is legit my home entertainment. Paired with my AirPods Pro 2 it’s seriously better than a TV anyways. If they made the 15” back in 2020 though, I’d have definitely bought that since I’m dang near legally blind wo my glasses on. This was neat to watch, we live vicariously through Luke on breakdowns 😂.
The "Power-up" problem could have been then Touch Bar, since the touch bar logic is an iPhone processor that also controls Security of the MacBook Pro. Not sure...
I'm honestly not sure why you thought this would work. I would assume Apple links most of the hardware at the most base level. Also, it is possible that there is just one little chip in the screen assembly or keyboard/trackpad or even the speakers that Apple somehow checks on boot or power and won't boot without "Seeing" said chip. But I appreciate your devotion to the attempt. Went above and beyond for sure.
What this could be useful for is when the M3 MBA13 comes out in October of this year but the 15 inch doesn't come out for another 1 months after that, then a M3 MBA 13 logic board swap into an existing M2 MBA 15 would be a real treat?
The parts are all serialized to go with a specific Mac. You ain't getting around that unless if you are creating a repair on GSX, Luke. Good luck being an authorized service provider just so that you can create a repair on that one.
This is happened by the battery. The newer MacBooks don’t start without a plugged battery. They also don’t start with a wrong battery ID like changing battery’s in iPhones. But in your iPhone you get a message, your MacBook won’t boot.
"As I'm always saying" 2:14 - I'm not native speaker but is it correct? I thought if there is "always" (repeated action) then it should be "As I always say", or I'm missing something?
Apparently the configuration of one of the zifs is reversed which causes the board to shorten so it does not turn on at all. Did you try to turn it on only with a screen and electricity and a battery? Have you checked the battery connection configuration?

I'm willing to be wrong but that's how I think I understand this shit so far.
that's really weird. I haven't gotten my hands on any m2 machines yet but with the m1 you can get a bare logic board to boot with nothing but the charger plugged in (you can confirm it booted based on the current draw using a usb-c power meter). So you could've started disconnecting things from the board until it would boot. I agree it's most likely the keyboard/trackpad that was the issue, although I also wouldn't be surprised if they did something funny with the battery. Fantastic video and great idea overall, would love a follow-up where you try to find out the culprit
on iPhones they do tie the battery to the logic board with a battery serial number. if you don't go through an authorized apple repair you would loose the battery health monitoring features. Probably something similar.
@@ThatOneGuyGreggers thankfully so far I haven't seen any issues with battery replacement even on newer macbooks. my theory was more that they might've made some small unnecessary change to the battery and therefore given it a new part number, which the other board won't recognize and will therefore refuse to boot. Either way, I wouldn't be too surprised if it's just more Apple serialization BS as usual
@@ThatOneGuyGreggers u can program it but the message still on i think
Mutiple componets have their own ids, and i believe the massive amounts of differnt ids may have prevented it from booting too. (Display id, battery, etc.)
It’s funny how Luke is being a little more sassy than ever 🤣
The boards probably check for matching hardware serials on different components. Apple is becoming an e-waste nightmare with how hard they have clamped down on their machines not being user serviceable.
Great video so interesting and fun to watch. I remember old laptops when you could replace almost everything.
U can also do that now just not with apple things cuz u know
Me: Tim (Cook), what's the point of MBP13 with only chip upgrade?
Tim: The new models are more Luke Miani-proof.
Luke: cracking his knuckles.
This video was awesome. I loved the energy and genuine shock when the M2 board didn't boot. There are a few minor component differences and I am sure it was something with initial BIOS load validation or some such nonsense. Either way, extremely entertaining, cheers.
BIOS is specific to non-Apple Intel computers. Macs, including Intel Macs, have never used BIOS.
Did you place the screws back in before booting? Cause some laptops use screws to complete the circuits in logic board.
Also other companies make sure their logic board works only with the original chassis. How? idk. I could very easily find out if i had such devices to play around with and time. I completely love disassembling laptops much more than desktops. Great work.
Next video: making a m2 12 inch MacBook!
The m1, m2 and m3 macbook pros are with the notch, are these macbook airs? No, because the m2 was also a notch one
It looks like Apple has gone to tremendous lengths to make sure people can't just swap parts in these computers making people have to buy a new machine if a part fails or to have Apple fix it for a charge if out of warranty!
Your problem is, you want the thief to have your hardware. Now it doesn't make sense to steal a Mac or iPhone. Even to replace parts and that is great news.
Planned obsolescence and capitalism. Thief exist because capitalism
Hey Luke. I've been following you for a while from the UK. I do repairs and tried the same thing in a customer's machine. It's actually possible to swap the board, but you must swap the trackpad in order to turn it on. The keyboard and other components are actually fine. I just thought to let you know. I love your videos on content. Keep up the good work.
I’m surprised it didn’t work considering that nearly the entire computer is on that logic board. Also if Apple were to offer an “upgrade” logic board it would still be very expensive since all of the core components are within that single board. It’s more like replacing the computer than “upgrading”.
that motor roaring when you said shut up at 5mins in, perfecto.
Luke, that was really weird. I wonder what Apple did to lock down the boards?
Ive stopped at 00:40 . Apple made sure you cant upgrade the internal storage of the Mac Studio… no way this will work.
You need to swipe the T2 chip, which stores the unique signature of the whole system in the "secure enclave", not the touch id button alone.
there is no more T2 chips in Apple Silicon macs, the secure enclave is now built into the M2/M1 chip itself
There is a LID ANGLE SENSOR at the top right corner, it has a chip paired to the logic board that's why I didn't turned on, cheers
Loved the video Luke! It felt different than the normal video out there and I really enjoyed it.
Great video. Luke always has original ideas. Never boring.
I'm curious if you can add another 256 Gb module in the empty space and upgrade it to a 512 Gb. Would it be possible? maybe get it from another dead MacBook Pro.
Would run into the same problem various experimenters did with trying to swap the flash chip modules on the Mac Studio. Without reprogramming the controller itself with the parameters of the new storage layout, it will not function at all, or at best you'd still only be access the original amount of flash.
It is probably some parts pairing between the logic board and the 1. Display 2. keyboard 3. Trackpad 4. Battery BMS 5. Lid position sensor or some combination of these.
Ex-Genius here.
1. The screw you removed from the heat sink we call it "super screw"
2. The swap didn't work because you don't have access to System Configurator (not to be confused with Apple Configurator). System Configurator is only available through AST2 and must be run on all post 2018 macs that had the MLB replaced.
No T2 chip on M1 or M2
Wait. So you are no longer a Genius. How does that work??. Like how do you go from Genius to dumb??
@@lonnygallant827 Thanks for the correction. I meant to say all post 2018 macs
@@Wilbur-em1hw Hahahahaha
So this actually could have worked if it wasn't for Apple's dickheadery in allowing user upgradability?
"Miami Luke" knows Apple products better than most Apple engineers....
Finally a girlfriend appears from the cracks in the walls! The 'Luke Miani is probably gay' rumours are finally over. Love your videos Luke! 👍
Luke Miani: What happens when you try to UPGRADE an M1 MacBook to M2?
Louis Rossman: LOL
There are a few parts I may guess could be the culprit: screen, battery, keyboard, trackpad, maybe even the WiFi connection via the cables. I recently swapped the motherboards of two old Dell laptops for fun and it refused to display an image because of the screen. The issue was I had to fully drain the CMOS battery and then it would boot. I have no doubt Apple found any way possible to lock down the MacBooks from being upgraded/repaired.
this isnt for apples gain, its called part out protection.
Now try to put an M1 or M2 internals into a 2020 13" Intel MacBook Pro.
Did you happen to try connecting the MacBooks to an external display to verify that there was no power and not just a simple case of no video signal to the displays?
You’d have clickable trackpad, starting noise, lit keyboard if that worked
Yeah, I had it connected to apple configurator
Two options are either voltage or failure of some device. You can try to use the M2 power supply unit (then we will bypass the battery). But I think most likely the "Bios" of a Mac (of a specific generation) is able to work only with a narrow list of hardware - after all, they don't need more.
Foam cover over wi-fi antennas is so that if you squeeze / dent the bottom case in your school bag and generally mistreat it, the metal bottom case doesn't short on the wi-fi antenna's causing reduced reception. (I'd guess)
5:00 lol that's the Ricky Gervais's way to say fxck off lol
No one, not a single soul
Luke’s brain “I wonder if I can put an M2 chip in the M1 pro”
Mac OS generally works by doing a scan for expected hardware and checking it can make system calls to it before continuing boot.
I’m guessing Apple has made each config SUPER specific.
This is as opposed to previous Apple hardware. My 2015 iMac is is composed on 95% the same hardware as my late 2014 iMac.
My guess is that the parts on each upgrade for M series macs has, at the very least, slightly different hardware ids
My question remains “can this be hacked around?”
Here is my experience, again with the iMacs I own.
You can swap displays on these things, and they are “backwards compatibles” for RAM modules and other things. The only trick is because of that system call test issue, you can hit boot issues.
But if you add hardware IDs to opencore (the boat loader for older macs that allows you to boot newer versions of Mac OS, as long as the OS itself supports your hardware. Example, 2012 and earlier macs recently got bumped down because Mac OS removed support for a specific codec that the intel chips of that era and before need to boot properly (something to do with graphics) so those won’t run. Anything newer will run fine, as long as you have reasonable expectations for your hardware. My Late 2015 is kind of just on the edge of not running Ventura all that well. But good enough for me ymmv, but anything newer than that is going to work fine.)
My question is, once hackers get access to M1 in the same level as they have intel Macs, could the ID numbers for relevant parts in the old Mac and if that would facilitate the upgrade. Given the priorities of Apple Software, it would. It surprise me at all if the old system check method was still the exact way the new Macs worked.
Luke seems more animated than usual in this video. I can only come to the conclusion he was hitting his sponsor’s sauce before recording. 🍸
Perhaps a iFix it tear down will answer your questions as too why the switch didn’t work!
iFixt tried this and failed too
Try swapping the battery’s as well. Apple serialized the batteries in their phones. It probably won’t work without the proper battery. Test it by unplugging the battery and connecting power to see if it turns on.
"What happens when you try to upgrade an M1 macbook to M2"
*you wake up from the simulation*
Could it be the display's plug pinouts are different which somehow causes a short and prevents the machine to power on?
Potentially Apple may have done what they did to iPhones, and paired the logic board to the screen, so in the event the screen gets damaged, they have to use their magic proprietary software to get the logic board paired to the new screen in order to boot?
It may be that some of the connection points have different pin configurations from the M1 unit to the M2 unit. It would only need to take a few differences to prevent the M2 logic board from working in the M1 unit. Also additionally, the bios microcode might not allow such a change.
macs dont use bios, its the fact that its a different screen, trackpad, whatever assembly that stopped it. its called part out protection so no one, even if they have the mac, they cant steal your data.
Fyi there could be a voltage difference between the circuits in the m2 chip that could require either less or more power. The total reason could be the supply of voltage going to the main power board causing a voltage miscommunication that interferes with initializing the new m2 board. In addition there would be several components that are not compatible with the board just like any other laptop. Yes it may be apple but they want you to buy a new laptop instead of fixing your broken or current one. Usually when the system boots it does a system check to see if any components are compromised then boots once validation is complete. But if you didnt here the fans spin on startup thats because there is a voltage issue.
Isn't every component on a modern Mac serialized? My guess the board detected that the generations were not matching up.
It could be that one of the reasons why you made the video, (and why we expected it to work) is because the Space Gray color of the macbook with the M1 is more beautiful than the computer with the M2, So, because you would buy a new one in space gray with m2, when you can move from m1 to m2?
Me suffering and worrying for fear of breaking the RAM clips in my dad’s 2011 ASUS and this guy opening and playing around with two laptops worth several thousands each 😂
do not connect the lcd screen cable. Connect to an external monitor. display output pin is re-programmed, which could short one of the power rail.
Please do the framework laptop upgrade just to show how easy it is possible for companies to actually make swappable boards.
Good idea
truly unfortunate, i actually had to swap my logic board once to fix my macbook
M2 can consume 6W more than M1, maybe some other component checks the wattage of the logic board.
So, the LCD needs to be paired to the logic board. Without this, there is no video..
If it is a different interface on the keyboard and trackpad, you could try not plugging in the zif ribbon cables for the keyboard and trackpad. Assuming you can still plug in the power button/fingerprint reader, the computer should boot up without any keyboard and trackpad connected, although you obviously would not be able to login unless you plugged in a usb keyboard.
Do not respond to impostors of this channel who reply here. They will take all of your money. Be careful.
Learning that it doesn't work is also really valuable. 10 years from now there will be a Computer-Clan type channel that complains about this.
You have to consider which devices are security locked. I know on iPhones, that means the camera is locked to the motherboard so swapping the camera stops features from working for security reasons, so if its the same in the MacBook, then changing the touch ID and motherboard won't work, you'd have to extract the camera module and swap them over too. A bit like those people that swapped their Mac Studio modules and wondered why the Studio wouldn't boot.
I can tell you right now it’s not for security reasons, it’s so apple stops you from replacing and repairing your own phone. Apple just loves serializing parts of the iPhone to stop independent repair. For that matter I’m 100% sure that apple made it so the device won’t boot because there is some identifier in the hardware saying it belongs to m1 (like diff voltages within the hardware or different pin outs) or some serialization denying the possibility of booting if the parts don’t quite match.
I baby my M1 MacBook Air so hard. The couple times it’s left my bedroom it’s been in a sleeve and I kept it in the passenger seat of my car lol. I’d never be able to take the bottom plate off unless it was broken and that was my only option… even then I’d probably be weary and do it in a room with zero dust/wind and spend like 8 hours doing it as delicate as possible.
I don’t even have a smart TV anymore.. gave my nice Samsung 4K to my nieces, this MacBook is legit my home entertainment. Paired with my AirPods Pro 2 it’s seriously better than a TV anyways. If they made the 15” back in 2020 though, I’d have definitely bought that since I’m dang near legally blind wo my glasses on.
This was neat to watch, we live vicariously through Luke on breakdowns 😂.
The "Power-up" problem could have been then Touch Bar, since the touch bar logic is an iPhone processor that also controls Security of the MacBook Pro. Not sure...
hey LUKE, are you trying to trick us...this is still the M1 logic board that you are installing....
I'm honestly not sure why you thought this would work. I would assume Apple links most of the hardware at the most base level. Also, it is possible that there is just one little chip in the screen assembly or keyboard/trackpad or even the speakers that Apple somehow checks on boot or power and won't boot without "Seeing" said chip. But I appreciate your devotion to the attempt. Went above and beyond for sure.
Because it worked with older MacBooks. You could put a 2012 MacBook Pro logic board into the 2011 model.
What this could be useful for is when the M3 MBA13 comes out in October of this year but the 15 inch doesn't come out for another 1 months after that, then a M3 MBA 13 logic board swap into an existing M2 MBA 15 would be a real treat?
The parts are all serialized to go with a specific Mac. You ain't getting around that unless if you are creating a repair on GSX, Luke. Good luck being an authorized service provider just so that you can create a repair on that one.
I mean yeah apple does this with the newer iPhones but where did you find out that this is the case here aswell?
Luke: Why would anyone want to do this?
Me: ?
Luke: Because I CAN....MWAAAHHAAHAAA!
Me: This is Apple you realize....
Swap individual components one at a time to see what is causing the issue
3:30 yep I saw that the chips right away obviously this is easier to spot
The ssd only having 1 module instead of two makes the ssd speeds substantially slower
This comment makes no sense
@@PedroPauloAmorim Makes a lot of sense you just don't know what you're talking about. 2 drives in raid 0 will have faster speeds than 1 drive.
This is happened by the battery. The newer MacBooks don’t start without a plugged battery. They also don’t start with a wrong battery ID like changing battery’s in iPhones. But in your iPhone you get a message, your MacBook won’t boot.
Everyone else: M2 MBP IS BORING lol
Luke: imma swap da boards baybee
A digital signature in the logic board could be possible.
For someone with a repair shop I think its a great video. Customers do usually have some crazy requests
"As I'm always saying" 2:14 - I'm not native speaker but is it correct? I thought if there is "always" (repeated action) then it should be "As I always say", or I'm missing something?
I fully expect every part to be serialized, from the cameras, to the screen, and the battery, requiring a complete swap.
I was thinking the battery as well
Apparently the configuration of one of the zifs is reversed which causes the board to shorten so it does not turn on at all. Did you try to turn it on only with a screen and electricity and a battery? Have you checked the battery connection configuration?
Wow, that was a lot of work. You put in a lot of time man. Thanks for the great video. And for the other folks... don't try this at home :)
I think the reason it didn’t work is because of the display and other peripherals are serial locked to the logic boards maybe 🤔
The question now, can you downgrade an M2 to an M1? 🤔
Interesting, checking some voltages on the board would have made this more informative :)
