Well, for anyone who has/will have same issue as mine, when clover Is loaded and your about to choose the Catalina installer, disk, highlight the drive and click “space” on the keyboard , tick “set Nvidia to vesa” & “disable KSLAR” seems like only these tow managed to let me install properly the Catalina on my system spec while my monitor is connected to the GTX1070 ti but of course doesn’t use it as a graphic card? Something like that...
So what is left to do for me is, Airdrop, doesn’t seem to work for me, as I mentioned above, same issue
