Trouble with Catalina no boot up….
Hello everybody I haven’t been on here in years I have had nothing but trouble with Catalina now my iMac is stuck on the Apple logo screen and I’ve tried every start up key to no luck I am a longtime mac User all the way back to the old Quadra days I’ve had G3 G4 quicksilver‘s and currently (new at the time) have a 2013 iMac with a i7 chipset maxed out RAM just trying to get it to boot up at this point very frustrated…… I’ve had zero problems with this computer till Catalina yes I’m definitely going to go back to High Sierra or something around there any help would be appreciated it’s stuck no matter what keys I use.
Thanks in advance, Scott
