2 MacBook crashing at installation, while creating user
Hello everyone,
I got this MacBook, that seems to have a RadeonGate issue. Whenever I tried to boot it from disk or from usb, I got to a white screen only.
After couple SMC resets and PRAM resets, I didn't get much further as well.. I then tried disabling the dedicated GPU with the nvram command (nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00). I then managed to somehow boot into recovery and disable csrutil. However, all this process was ultra slow as well, so loading times are horrific.
Anyway, I then got to install MacOS El Capitan from my thumb drive. However, after going through most of the process, when trying to create a local user, the macbook crashes. Tried that 3 times in a row, with the same result all time.
The following images show it:
So basically, I get to that point (again, with heavily low perfomance), I enter the details, clikc on create and then after about 1-2 minutes, the macbook crashes and restarts and shows that message from the second image...
Do you see anything else, that I could try to get this fixed?
PS: Onboard diagnostics doesn't show any error.
