I have a Mac 5,1 that I recently installed an AMD 6900xt into and added the Pixlas Mod for the power increase. After doing the upgrade I lost the display screen however I was still able to remote into the computer through screen sharing. I was also able to rarely get the boot picker screen if I held the option key at startup. It didn’t always work I would say 1/4 the time. I have HDMI and DisplayPort Connections and neither work.
I was hoping that adding OCLP to the machine and updating to Tahoe would fix this issue. I downloaded the program and installed Open Core onto the computer. I had OCLP download and install the EFI and Tahoe onto a clean USB stick.
When I restarted the computer I didn’t get the boot picker screen and tried a number of restarts to no avail. I also found that if I didn’t hold the option key on boot the Mac would shutdown about 1-2 minutes after being turned on. I tried using the arrow keys on the keyboard and blindly selecting in the right order the update files. This hasn’t worked.
I was unable to find any work arounds to this problem.
Any Suggestions?
