Ok, I have a Mid 2012 Mac Pro that my old workplace gave me when they closed their doors. I hadnt't turned it on in a while so today I got to thinking about restoring it to factory fresh and selling it.
1) Tried booting into Recovery mode using every possible combination. Command-R, Option-Command R, Shift Option Command R. Nothing, boots up like normal.
2) Tried booting into Safe Mode (or whatever it's called) by holding Shift. Nothing.
3) Tried reseting the PRam and Vram and SMC and god knows what else and trying all the above again, several times. Nothing, boots like normal.
At this point I decided to update the OS to High Sierra, thinking maybe there was something corrupt in the OS that wasnt allowing it to go into recovery mode. I upgraded to High Sierra, repeated everything above, nothing, still cant get into Recovery Mode.
4) Created a bootable USB drive using the official Apple method via Terminal. Went as planned, seems to have created the Bootable Install USB successfully. In Disk Utitilty is reads as Bootable. So I go to Startup Disk, select that drive. Here I thought, ok, this is definitely going to work. NOPE, boots like normal!
5) Create bootable USB via an application (forget what it's called at the moment) but it's one of the apps that somewhat automates the process. Choose the USB from Startup Disk. Computer boots normally.
I've also tried 2 different keyboards (in case the any of those key combos didn't work for some reason) and created the Bootable USB using 2 different USB sticks.
I'm really grasping at straws here but here are some likely far-fetched ideas:
1) Is it possible that there is some security software embedded deeply into this machine that is blocking any of these recovery attempts?
2) Is there some hardware problem that is preventing keyboard inputs from happening pre-login?? This wouldnt really explain the bootable USB not working though. Unless for THAT to work the PRAM must be reset which hasn't actually been successful because the keyboard input isn't working. (I'm talking in riddles, I know, bear with me)
As you might be able to tell, I'm at my wit's end. I've basically deleted all apps and personal data off the computer but I feel it isn't right to sell the computer in this state, at least without disclosing it. Or having to disclose it is going to give someone an excuse to totally lowball me on the asking price.
Any help is very veryyyy much appreciated!!
