I am troubled by one thing. I have direct upgraded flawlessly via the App store since Sierra. When I tried with Catalina, it downloaded and then launched. I started the upgrade, and, when it did, the first reboot Clover did not display the Install MacOS selection. I rebooted and repeated the steps, and the same thing occurred. I started from another drive. I checked to see if the Install folder was created, and it was there. Cloned the drive to a spare, and I tried using an external connection with the same results. Finally, successfully upgraded with USB installer without issue.
I want to understand what went wrong. What am I missing? I had upgraded all kexts and Clover prior to install. Did the Mojave 10.14.6 upgrade from App store two weeks prior without issue. Other people with same config as mine upgraded from App store without issue. What am I missing?
