iMac Late 2013 end of Support
I have an iMac 21.5, Late 2013. It's still fast, and I don't have any issues with it. Although, I'm starting to wonder when it will no longer receive MacOS updates. The Late 2012 iMac is the oldest one that supports Mojave. Would it be safe to assume that 10.15 would be my Mac's last major update?
