Looks like my USB installer also stuck due to this. Do you mind to share which patch you applied?Update to 10.15 went ok. Had to install the EC patch to get it to boot though.
Anyone notice a hit to GPU Geekbench scores? I went from 175k to 154k on my Vega Frontier...
I have a similar system I am looking to upgrade (P55A-UD4P), would you mind posting which Kexts and Patches were required.Gigabyte GA-P55A-UD3
I had the exact same experience. 3 extra reboots at black screen with logo each time. But instead of rebooting my system would just shut down. I kept trying after reading that maybe this is the expected behavior and sure enough on the 4th reboot I'm logged into a fully functional Catalina system. It's a bit weird because this is not the experience I had on my native MBP. Suggestion for other users, if you're stuck on an apple logo just wait, if the system shuts down, turn it back on and try to boot again. Keep doing this at least 3-4 times before giving up.wao, i get desperate whem i saw for long time black apple logo and nothing. after each reboot would be near to 20 mins?
Sure, I got it from here:Looks like my USB installer also stuck due to this. Do you mind to share which patch you applied?
