Hi Gary, is there an easy way to check that all my installed apps are from the Mac App Store?
Patrick: If you look in Launhpad and click and hold to uninstall apps, the ones with the X will be App Store apps. The ones without will either be system apps (Mail, Reminders, Contacts, etc) or apps you installed some other way.
Hello Gary, I have an iMac from 2013 and I am limited to the last OS upgrade (Catalina, 10.15.7). Sometimes I wonder if my machine is becoming vulnerable, especially lately, when it slows down at times. It's a pity if I have to get rid of a good machine. Thank you for your reply.
Carlos: Apple is still releasing security updates for Catalina and will probably do that for another year now or so.
How do I delete an app which is not a Mac App?
