I've just managed to make fresh install of MacOS Mojave 10.14.6 on my Acer V5-573G. I have an observation to share with the comunity and to ask for help. During boot up at some point screen becomes destroyed (see Loggin.jpg). If I (blindly) enter my password I can login and (blindly again) send the system to sleep and immediately press enter several times, screen appears properly. If I later adjust display settings, set it to scaled 1600x900 (laptop supports 1920x1080, see DisplaySettings.png) then, during boot up, the system will shortly be distorted (black and white apple with progress info) but log in screen is ok. Later I switch to full HD using display settings and work. Before shutting down, I need to set it back to scaled 1600x900 and then to shut down. If I forget setting to scaled before shutting down, then I need to apply sleep + enter after login. I am using WhateverGreen and Lilu. I read somewhere that I need to set CSM Bios support. That option is not available in my BIOS. Any help is really appreciated.
