Mac 5,1. with 580 GPU (the recommended version). Latest Tsialex ROM etc. Installed Opencore 4 weeks ago. It worked for two weeks. Then it would not fully boot. I did a disk repair and it worked. Then failed again. It starts to boot, black screen with white Apple logo, then the screen goes black and the monitor reports its no longer getting a signal, and the monitor then never gets a signal.
I pulled the drives except for the Opencore drive - Monterey - and booted using the option key, with the Open Core install USB, and it seemed to re-install Opencore/Monterey. The OS booted but essentially hangs. When I try to do something, I get a spinning circle, either coloured or grey.
There is a file I need on the drive, which I cannot find without booting from Monterey. I can see the file while in Monterey, but when booted from Mojave, I cannot find the file.
If I format another SSD drive, can I boot from the install Opencore patcher USB Monterey USB and just re install ?
I don't want to re-format the Opencore Monterey drive, because it has the file I need on it. The SSD drive was a new Crucial 500 MX drive, 1 TB.
