Hi friends., I am working on MacBook Pro A2159 touchbar 2019. The old logic board was liquid spilled so I ordered another logic board from AE. Received it & all worked fine till I got to the Chinese login screen where the login screen password tobe entered. I tried to reset the password but it again gave me options which I do not know about the Apple ID. I formatted the onboard SSD. & wanted to change the startup boot sequence but in order to change it, again the password is needed for that too. Is there a way to get rid of this password?? The seller has not replied back past 2 days, how...

Hey guys!!

I’ve got a question here!
I have a MacBook Pro A1706 that needs the backlight cable replacement — the well-known issue — but the problem is that the code on my original cable is 821-00571-A, and the one I have on hand to install is 821-01229-A.

Well, I asked ChatGPT about it, and the guy told me they’re not compatible and it could even burn the backlight circuit!!

Here’s what the bot told me:

Hello,

I have a MacBook Air 13 inches 2014.

I have set a EFI password and I can't remember it : now I want to reinstall macOS and I can't because the MacBook is asking for the password.

I know how to remove the password with a usb programmer.
I plug the usb programmer to the motherboard and to my pc with usb, I read the EFI and I save it to a file.

Then I have to find this value in the file : $SVS because it indicate where is the password.

But I can't find the value.

I have attached the file​

Thank...

Hello Hello,

I have been browsing the site and gotten so much useful info from here, including extremely helpful boardviews and several other very useful types of information. I am very grateful to this community, as I have actually eeked out a living from buying salvage PC's & Macbooks and repairing them. So, thank you all in advance!


I have searched and found some useful information regarding my issue, but my case is a bit different than the info I'm finding. But if anyone here can give me any useful advice, it would be highly appreciated.
