. . . that's all the further it'll go. If I press the Option Key I get a Black Unlit Screen with no Backlight. But am left in the same place. This is the first time I've had any issues like this after having done countless installs.
The unit is a 15" 2011 MBP 8,2; 16GB/500GB. I've been running a 13" 2011 MBP 7,1 with no issues and am trying to migrate into the 15". And during a Routine Update to 15.3.2, this. Although one thing I've noticed and was hoping to fix is the onboard microphone won't work. An external will.
After spending quite a long time in this forum and searching the only conclusion I could come up with was the EFI Partition was corrupt. So I took the drive out of the macbook pro attached it to my 13 and installed OCLP 2.2.0 on it again. I put it back in and I get the same behavior. I thought I might do a full Over-Install, but didn't hoping that fixing the EFI would be enough to get the Startup Manager back and I could go from there. No Joy. Although during the last startup before all this mayhem, I did notice that there was and extra Volume in the lineup labeled "Update". That was the last time I was able to get the Startup Manager to come up.
Unless anyone else has any words of wisdom, I'll probably take the drive out again and do a full OCLP Update on it with the downloaded Install File as an external drive. Up until this it was running great and I was moving into it slowly from a clean install hoping this would become my new machine.
Any assistance will be greatly appreciated!
