Mac Mini2010,Deleted admin account and tried restoring mac os high sierra and can’t anyway ive tried! Says cant connect to recovery server or doesnt show disk after fixing with disk utility please help!!! I’ve tried restoring it with all options possible. Usb intaller,command + R and command+options+R and even shift+command+options+R and to no avail i get similar cruddy responses. My mac mini is connected via ethernet so its not a connection issue either. I’m truly at a loss for words on what to do here. I just downloaded 2 USB recovery installers from a friends mac running ventura and hopefully that will work when i try it. Honestly i think the issue is when fixing the disk in disk’s utility it won’t switch from Mac Os Extended Journaled To AFPS,If i can get that to switch to that then it should work because thats the error it gives me in installer log. So how can i switch it to AFPS or fix this???? I don’t have access to another mac at home so im limited
