Re: Macbook A1342 (820-2883-A)

it is hard, if not impossible to mach efi bios on mac

if you are removing password, its easier to read bios and discard password... pm me if you need help or post dump here

i found few dumps here, you can try, but ALWAYS BACKUP your org bios

I'm not sure if this will do for you but give it a try.
Remove one out of two RAM or add one if you have only one just to change the amount.
Boot and make NVRAM reset by holding 'command', 'option', 'P' and 'R' all together.

Glad to hear that sir, maybe that's way no $SVS in your dump

Re: Macbook A1342 (820-2883-A)
