Broken GPU -> Removed EFI password -> Black screen
Hello community,
I have a Late 2011 15” Macbook Pro bought in 2012. It had some upgrades done to it over the years and eventually the GPU died. We had it replaced many times but ultimate disabled in the firmware.
Then I somehow forgot the EFI password I set many years ago while reinstalling OSX. They did it in an Apple authorised service.
Now (since the firmware had to be reset) the problem is here again but now there is no display, just a black screen.
The machine chimes, responds to PRAM resets, tried reseting the SMC, takes charge and caps-lock lights up.
Esta é uma boa pergunta?
