I got the iMacPro 1,1 working on my backup drive after I changed the Boot order. I wasn't brave enough to sign in
to iCloud but I used Safari. It crashed once and the crash report looked similar to what I've seen with iMac20,2.
I didn't do an extensive test but it seems better with iMacPro1,1, the downside is the computer went to sleep and
wasn't responding anymore. USB didn't work, screen was turning on and off, all kinds of strange things going on.
I'm about ready to surrender and just live with the fact that I have to run Logic Pro at all times so that the computer
doesn't crash, everything else works great.
Is there something else I can try with iMac20,2? Take out Fenvi T919 card or using a newer OpenCore version (I use 0.61).
