27” iMac 2013 recovery mode
Just prior to getting pasting to Catalina, my Mac was sloooow as (I suspected maybe hardware / drive problem) it was recommended that maybe my OS was outdated so I updated. After a restart it took ages to update photos and then, stuck in recovery mode... and get this now
tried lots of online suggestions;
each of the above (except restore from time machine because backup too old) and also, many on Apple community. Any ideas please? If I erase can I still get a geek to recover my files.
