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.

Hey guys,

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

Hello, I am looking for any and all files related to the mainboard for 820-2565-A (13" Macbook Pro A1278 mid 2012) schematics/board view.
I looked through forum search results and google and was unable to find a board view file, I found a pdf of all the schematics but I don't know where the parts physically are on the board as this is my first macbook board level repair attempt.
The macbook charger has a green light, the battery has been replaced and OS reports Normal status but Not charging. After cleaning a corroded capacitor it crumbled off the board. There...
