Updated without any issue...
Updated Clover, Whatevergreen & AppleALC before starting.
Clover might boot from wrong partition after reboot. Select "Install Mac OSX from <your OSX partition name>" manually.
Tried updating to Catalina.... Finally after 2 reboots and update, got to the clover (5070) boot menu, but started boot loops thereafter... getting clover boot menu and getting restarted again & again .. please help.. tried -x boot flag, not helpful... If I add -v , the command line goes too fast.. Appreciate help here.. thanks.
