P pickett22 macrumors newbie Original poster Apr 12, 2022 5 0 Apr 25, 2022 #1 I want to Factory reset my Late 2013 iMac to donate. When I do the CMD+R+Start, then erase hard drive and then go to reinstall Mac OS, will it install what you had before? Mine is running Catalina, it wouldn't let me upgrade after that.
