Okay, this may be a simple question but. I have an old desk top computer Sierra 10.12.6 can I update the OS software to a more recent version i.e. Catalina 10.15? Or is it time for a new mac if I want to use new software on this machine. Seems a waste maybe need to take it to the local mac guy for a look-see
iMac 21.5″, macOS 10.12
