This is not the GPU fault as other answers have suggested.įrom all my research this is most likely a new battery needed. In case anyone else ends up here with boot loop issues with a 2011 MBP or similar years.

That is way cheaper than to go the now defunct Apple road of replacing a faulty board with another faulty board.Ĭonverting it over into a Linux machine makes the GPU bypass on a defective machine easier, but will not do much good for keeping it around long enough. The only real fix though is to either sue Apple like they deserve for lying on this to us all or to replace only the AMD chip in question. You might want to bake the chip for a flaky temporary fix like with the iBake procedure. No amount of SMC reset voodoo or the like will restore a GPU dead MBP. This bypasses the AMD GPU through a forced EFI variable. If this machine is still around then it can be partially resurrected with a procedure like this: As all MBPs from that era are defective by design it is impossible to keep them around for the amount of time you would expect from a quality product. This means it is one of thousands GPUs killed by inadequate thermal design that finally bit the bullet. Does this mean it has a dead GPU? I just found out that Apple's repair program ended in December 2016.

I also ran testdisk and recovered (at least I think so) the partition table.

I can ssh into the MacBook when booting with Linux.

booted with a live Linux USB-stick: it works, although I have to enter the boot option 'nodmraid'.

I cannot repair user permissions (thanks, Apple, for removing that functionality).

booted to single user mode: I can boot to Single User mode and run fsck on the different partitions.

tried to boot from an 'Install Sierra' USB pendrive: it recognizes the pendrive, but boots with the same behavior as a normal boot.

ran Apple Hardware Test (quick and extended): no failures.

Internet Recovery runs to 100% before switching to the grey screen

booted with cmd+ r: it doesn't boot to the recovery window, but switches to 'Internet Recovery'.

booted with d+ shift: no indication of any kind of different boot, same as normal boot.

It boots up until the progress bar is at about 80%, then it flashes to an empty grey screen, no login window shown, no Apple logo.
