** EXTREMELY IMPORTANT **
Make a full bootable backup of Catalina 10.15.3 before attempting to install 10.15.4
There seems to be a high failure rate with the update to 10.15.4. It may or may not be due to WhateverGreen. Like COVID-19, we don't have a solution for it right now. Don't take chances. If you cannot make a full bootable back right away, do not update.
I do not have WEG installed because I do not like it and the piker black screen fix works perfectly for me. I also use Opencore and VirtualSMC. Long ago I noticed that if you have more than one monitor plugged in things act strange during an install/update. I also noticed that the older OC version that I was using caused some garbled text on the screen during install rather then the apple logo but the bar was there and keep moving forward.
