After installing the Catalina patcher 10.15.7
there’s about 15 minutes to go of the installer and it goes blank on the screen
I leave it for another 30 minutes before I’ve restarted the Mac .
Mac Pro boots up but there is no display showing I get a notification on my phone saying that the Mac Pro is now using iCloud so I’m assuming this is a hardware issue with the graphics card. ? am using Nvidia Quattro 4000 Graphics card
I can boot into recovery mode and have use the macOS post install options including legacy video card patch option.
I can’t think of anything else I can use to make this work .
Have also tried and failed to get the USB to boot as not showing up as a start-up disk.
