Successfully intalled Catalina 10.15.7 on a PowerMac 5,1 mid 2012. However, it seems I have to reapply the post-install patches almost every time I reboot because startup stalls on the Apple logo. I then need to reboot from the USB installer, reapply the patches, then reboot to the drive with Catalina, and often need to reset PRAM in the process. Any ideas?
