Worked on a Mac Mini 2012 but I had to find a Win 7 computer. The drivers would not work on Windows 11 despite supposedly being compatible with them. Also when writing the fixed firmware, the writing process was bumpy, stopping at certain percentages for a while then speeding through others. It took nearly 3 minutes to write but it stopped at 100% and didn't verify. Luckily, it still worked.
nice. i used this tutorial for imac 2011 uefi firmware mods, but forgot to erase the chip first before writing back and verify failed because of it, so i was a bit stressed 😅
Sto provando ad installare i programmi che hai linkato qui sotto, ma non riesco a trovare il download del CH341A Programmer Files .... dove si trova il link per il download? grazie
I did everything the same, but it fails on the verify. I can't seem to get a good burn. Chip is a 25Q064A in a 2012 MBP 15". I've done half a dozen 13" models with no problem.
Try holding down on the shift key on the keyboard while selecting restart on the start menu. This is one way to access the BIOS on a Windows PC, it might work for your Mac.
kind regards: I have a 2012 imac that had the same problem as in your video with the image of the folder with the question mark... I left it on for a while and now it stays on a black screen every time I turn it on, the fan spins but it doesn't do anything at all... would I have to look for a bin file on my board to modify it or just deleting the key like in your case could it work? thank you so much
Looking for a bin file would be a great idea, provided it doesn't have any other issues. I would suggest you try using an installation USB to determine if there is an issue with the display.
@@aoeaster Thank you very much for the reply. When the screen still turned on, I created two USB with different OS Capitan and Yosemite but it never recognized the USBs or anything, only the mouse pointer came out. I also connected the internet and I got a hard drive with the planet Earth on top flashing. After that it did nothing, just a black screen, but the fan did work.
This simply clears the password from the chip while maintaining the original chip's contents. If your chip is corrupted, you need a working backup to reprogram your chip.
Not sure if its can work on windows 10 devices, but I keep getting a drive error with the CH341A Programmer application, then it says device state: NotConnected even the the device is infact being powered
Hello, excellent video, I have the same problem but with a 2019 iMac with an Intel processor, do you know a way to remove the EFI password without having to remove the Chip? Thank you
@@aoeaster Is that the chip that the iMac 2019 has is not the same as the one you have in the video, there are no tweezers that can hold that iMac 2019 chip, there is no way to hold the chip with tweezers
Congratulations friend, nice video, I wanted to know if this method also works with Mac mini 2020 with M1 chip, but I don't even remember the password, help me if you can, friend kindly

Gracias por el video muy intrutivo tendría un video para mac A1418

I’m glad it worked for you.
I had the same problem with my old macpro 13, i hope this tutorial will work on my macpro 13, i'll share the result later

Sto provando ad installare i programmi che hai linkato qui sotto, ma non riesco a trovare il download del CH341A Programmer Files .... dove si trova il link per il download? grazie
Can I use the same programmer kit to MacBook pro retina 13 mid 2015 with EFI bios locked.
I haven't tried it, but it's worth the try
HI! Thank you so much for your video. I've a question: is it possible to run windows 7 on parallels desktop whitin this procedure? Thanks
It's not possible to do so within the procedure. The system is locked and inaccessible for use at this point.
Thanks, but what I was saying was to install windows 7 on parallels instead of an old Toshiba as you did in your video

My main computer is a mac pro 1,1. I use windows 10. I would like to have something of a bios setting. Is it possible?

Hello, does this work with corrputed ufi chip on imac 2011 21.5"? Its corrupted as it has 9 beeps on startup.
This simply clears the password from the chip while maintaining the original chip's contents. If your chip is corrupted, you need a working backup to reprogram your chip.
thank you sir
Not sure if its can work on windows 10 devices, but I keep getting a drive error with the CH341A Programmer application, then it says device state: NotConnected even the the device is infact being powered
Try downloading and using AsProgrammer software with the CH341A Programmer.
Hello, excellent video, I have the same problem but with a 2019 iMac with an Intel processor, do you know a way to remove the EFI password without having to remove the Chip? Thank you
I know that iMac 2019 has an EFI chip on board. If you can locate it, you can try to remove the password using the method described in this video.
@@aoeaster Is that the chip that the iMac 2019 has is not the same as the one you have in the video, there are no tweezers that can hold that iMac 2019 chip, there is no way to hold the chip with tweezers
Does this work with macbook air also??
I haven't tried it on one yet.
@@aoeaster oh
Congratulations friend, nice video, I wanted to know if this method also works with Mac mini 2020 with M1 chip, but I don't even remember the password, help me if you can, friend kindly
I haven't tried it, but from some sources, the process might be different from this.
can you also make for macbook pro?
I would, if I come across one.
i can't fint the $SVS code in HxD, is there any other posible othe code? $FPT or what?
I'm glad it helped!
Will it work on a imac 2017
Yes, 2012 to 2017 imacs should work fine with this method.
What if the I mac don't have screws to take out the disk
“The startup diks is unavailable” 💀
how do i know what chip i have
If you can access it, Google search the number printed on the top of it.
Doesn't find $SVS on mine!?
Ensure you don't have any error in the reading of the chip.
