If you want to see how much work was needed to revive this thing, go watch Collin’s video. He repairs the board cut, adds NAND flash, re-provisions the board, and a litany of other genius but nightmarish stuff to get the darn thing chooching again. ruclips.net/video/reQq8fx4D0Q/видео.htmlsi=L_2kWOjBTQSMycdb
So glad you had the chance to take a look at one of these weird Macs! The repair and restoration of these boards represents about a year’s worth of work and research, and needless to say I am very happy with the result!
Mild correction: the 'Mac Mini' tag and thunderbolt logos on the unit are just a result of Collin reusing a Mac Mini casing-since his board came loose. The original chassis used for the DTK had no thunderbolt logos on the back, and only the regulatory logos on the bottom.
I'm quite surprized he didn't know that since Colin's video was already up 4 months ago. He obviously didn't watch it because he also talks about the serial number on the case "is a complete fraud".
As a developer I had one of these machines. The machine was slow and Rosetta was buggy. I thought this didn't bode well for Apple. When I returned the machine and got a full M1 as a replacement, I was very surprised by how snappy the machine was compared to the dev kit.
A while ago I bought an iPhone but recently I bought a Mac for the ecosystem and it was a good decision. What I like most and what surprises me is its performance and screen.
My office BNH Software and precisely that fear made me get it out of there, I am happy because it has worked very well for me, even better than in Windows
As a small developer at the time, I immediately applied for the DTK after WWDC ended. I got approved and the terms and conditions were sent over. Literally took 30 seconds for me to realise it was a horrible idea. £500 and I had to send it back for no refund? And if I didn’t send it back, Tim would send Craig to my house and kidnap my family… no thanks.
I worked on a team that got one of these - primarily to test Apple Silicon as we replaced our dedicated mac app with a Catalyst version adapted from our iPad app. I did most of the work getting everything to compile for the new architecture (and boy was it a wild west when it came to external libraries). The DTK itself was definitely a bit buggy and had several quirks (I had to use DFU mode to reset/fix it on 3 separate occasions). But it was exactly what we needed to get the app ready and tested by the time the M1 came out. On the whole it was worth it for our team, and it was fun to get a glimpse of the future for mac.
I remember when they did the Intel transition, if you got the dev kit, they sent you an Intel iMac as a replacement for them when they did the dev kit reclamation. Much classier.
Everybody forgets the transition from 68K to PowerPC. The emulation layer was so low-level that you could switch between 68K and PowerPC code on the fly. At first, even the vast majority of the OS was still 68K code running in the emulator. They could get away with this because the emulator was extremely good from a compatibility standpoint, and while the performance wasn't amazing (at least until they replaced the interpretive emulator with a dynarec emulator), it was still equivalent to a midrange 68K mac.
That M1 release era was awesome. Working in printing our prepress dept. uses macs and we had to put off the upgrade for awhile until Kodak got with the program (M1 support, etc.) Sucked that one developer kept us from upgrading as long as they did
someone needs to commend the storytelling and pacing in this video it's really well done. whoever's scripting and editing needs a 15% pay rise. i enjoyed seeing dosdude1's work given slick editing back to apple's keynote. you two should collaborate again. dosdude is such a legend, i love that he's doing extremely delicate and huge cost of failure jobs off the back of an old dvd drive because if you turn it upside down it's flat enough.
Maybe that's why they will downsize the Mac Mini that will be announced in a few days or weeks, because everything is really embedded within like shown on this unit taking little space, and there's no need of space like the older Mac Minis.
I’m a little surprised that you actually got the DTK to “work”. I would have thought that maybe Cupertino might have used the Dark Apple Magic to remotely brick any surviving units, such as barring any A12Z MacOS devices from connecting to their servers, or even sending some kind of “Kill Code”
And kudos that he doesn’t used the sponsored video as his sole video this week! maybe uploading the normal video first and the sponsored as a “Bonus” is the trick.
@@yaowww Ad Sense revenue took a hard dip many years ago. It's a drop in the bucket and isn't enough for these channels to be sustainable, let alone profitable. Hence the rise of ad integrations, dedicated product videos (like the vacuum one), and so on. It pains me to see that people take it all for granted. Don't like the vacuum video? Who gives a shit, don't watch it, but it paid for the next 10 videos, so it's a win for the creator.
I remember when WWDC2020 happened, I was watching your videos constantly, and I was really excited to hear your thoughts on Apple Silicon, its cool to see you talking about this unique transitional era after 4 years.
I watched a video which revealed that a RUclipsr had sourced the main board for this Mac mini from the company paid to destroy them. This company cut through a number of tracks close to the edge of the board as happened to your Mac. The RUclipsr was able to reconnect the cut tracks and refitted a flash chip. What was impressive was that he knew what numbers needed to be flashed into this chip to make it work before he soldered it onto the board. He mounted the fixed board into a Mac mini 2018 model and successfully installed MacOS on it.
technically china ship the logic boards by the boatload. They snip a piece out typically but have been proven repairable! Turns out watching on, that same friend that sent you it i watched repair it haha!
I think the most interesting thing about the Mac transition kit is that it’s cinebench performance is nearly the same as the 2013-15 MacBook Pro 15 inch models
But they don't even state when it is available. So the 49 dollars could potentially be a suss moneygrab. Maybe better to pay the 351 dollars extra for the vacc
I had one until Apple asked for it back. Totally NDAs on everything (DO NOT TEAR IT DOWN OR BENCHMARK IT) but I was still really impressed even with the Beta builds of the OS. Actually I managed to make it run really well; Maps was outstanding and fast, even with the A12Z. My focus was CLI stuff and I helped with the effort to port Homebrew and a bunch of open source code over to ARM - particularly stuff with x86_64 assembly as I'd been a ARM assembly coder since the first ARM chip on the Acorn Archimedes. Before long though, Apple wanted everything back! Yes They tracked me down and they did credit me the full amount but it had to be used within 12 months! Still, was great to get an early look and I waited for the M1 MBA before diving in again.
You saying that Apple finished with Intel with their tenth gen core i chips made me think of a future where Apple was still working with Intel when they released their 12th and 13th gens. With Apple's restrictive designs and the lingering death of those chips, I wonder what kind of catastrophe would have happened. Apple definitely dodged a bullet without even knowing!
I thought I was having a cerebrovascular event when I kept hearing MOSFET batteries 😉. Cool vid man, I was curious about these things. Pretty innovative idea actually. Good example of Apple thinking outside of the box.
i think they gave $500 gift cards when they were sent back in, so basically your money back towards an apple silicon device. or to spend on your genshin impact addiction
fun silly little thing: the recovery screen when it’s bricked is a sad mac from the macintosh days. i think this got changed to the normal one when big sur launched-
This isnt a dtk chassis. You can tell that by the fact that this board was sent back to apple, because it has been sliced. It will have then been recovered from the trash and repaired (theres a few videos of this) and then put in a mac mini chassis with a mac mini power supply. (Just saw that quinn mentioned the slash, it would have been nice to mention that it was put in a mac mini case)
The "instantly powers on when you plug it in" problem is probably because you had no batteries in it. I had one back then and it behaved like a normal Mac Mini and I kept it turned off when I wasn't using it.
The fact that this thing had twice the storage of the base storage in even a new M4 Mac is shameful. I hate that they continue to make 256 GB the baseline and charge so much to add more storage, and that, of course, it is not at all user-upgradable.
“Dear viewer, that was the problem: my brain.” I feel like the world would be much better off if people weee more willing to realize this and laugh with it.
Some continuity errors? CPU shroud was open before in a couple of shots before actually opening it. Great video though. Will you be reviewing the latest iPhones?
These ADK's could be a catalyst for something special. If jailbreaking ipad OS alongside dualbooting is still possible, in theory it should be possible to fudge mac OS on to one of those slabs?
@17:45 I wouldn't have logged into the app-store with your personal account. If Apple detects that you are using illegal hardware, they could say that you violated their terms of service and permanently ban your account along with all of your downloaded purchases that use that account to validate the license. That happened to me when I jail-broke my Playstation 3. Sony detected my Jail-broken PS3, banned my account and I lost access to all the games I bought online and installed. Not just for the Playstation 3, but also games for the Playstation 4 because I bought them using the same account.
It's a shame that Apple never built a separate Apple Silicon GPU coprocessor that could run AAA games with ease. The one-chip strategy seems a bit lame for a company with so much cash. Apple could put that processor in a Mac Studio or Mac Pro to make them really powerful graphics machines. I guess Apple doesn't feel it's worth the time and effort to do something like that.
GOG Galaxy has never worked well on the Mac, in my experience. But you could download your game directly from the site and install it that way. You don't need Galaxy to use your GOG games.
There been a few of these boards cut near the power plane area this was done by apple purposely to render the hardware useless only one person on youtube was able to repair the cut pcb and rewired the broken traces near the power connector
I wonder if Fedora Asahi Remix (a version of Fedora Linux for Apple Silicon) runs on it. That would be an interesting way to keep it relevant and enable some comparative testing. I can only assume that the Arm-native apps available there would be more forgiving of the older architecture.
I don’t know about your discovery, but my DTK definitely worked with my thunbernolt iMac for 40gbs network trunk between the two computers, and the network bridge apprared in macOS as a thunderbolt bridge.
Imagine if Apple wanted back all Developers Kit, just because there was a way to install iPadOS on these, because it's literally an iPad board somehow. Of course I'm just dreaming/joking

looks like the DTK ran at 1ghz, the M1 runs at 3.x so...
So, when Quinn said that people had to return the DTK with a compensation of $0, was that false? Did developers get an M1 mini when they returned it?
A while ago I bought an iPhone but recently I bought a Mac for the ecosystem and it was a good decision. What I like most and what surprises me is its performance and screen.
And the best thing is that Office works incredibly well for me, I don't have to worry about Windows 11 ever again.

As a small developer at the time, I immediately applied for the DTK after WWDC ended. I got approved and the terms and conditions were sent over. Literally took 30 seconds for me to realise it was a horrible idea. £500 and I had to send it back for no refund? And if I didn’t send it back, Tim would send Craig to my house and kidnap my family… no thanks.
Too bad, they actually did give $500 back when you returned it. This was due to the developer feedback.
I worked on a team that got one of these - primarily to test Apple Silicon as we replaced our dedicated mac app with a Catalyst version adapted from our iPad app. I did most of the work getting everything to compile for the new architecture (and boy was it a wild west when it came to external libraries).

Uh, I’m not so confident that’s correct as the DTK documentation explicitly states there is no Thunderbolt.
love your videos, so unique :) one of my fave RUclipsrs
a spectacular art created by apple but the weirdest sick of them have to destroy it
This video seems to be shot in a surprisingly darker environment than your other videos.
"You are late on your payments Linus..!!" n Hahahaha..!!!
Oh, you've got my Mac's dad! (M1 mini)
I can't believe Apple had the balls to only offer $200 back. Oh wait... yes I can.
"worlds worst speaker" guess you never installed the driver on a 486 to get pcm sound through the internal beeper then. 🤣🤣
Apple wanted to destroy this board. Thats why it has that weird thing.
Yeah Apple will never invite this guy to a keynote after this that's for sure

Same here.
No Apple didn’t attempted to destroy, they just don’t want to bother supporting these
This was put together from just a motherboard, and it's not made from developers HW.
