So I have a two year old M1 iMac. We have two full profiles on there and cannot upgrade software as the memory is low. Is there a way to delete the admin and have the secondary user keep all their files (school work etc)
Why not backup the Mac, wipe the drive and then do a clean install of the OS you want to install? After you get done, you can decide which files and or accounts you wish to copy over. You have to have 1 admin account.
