Ever since I upgraded to macOS Catalina 10.15.4 on my Mac mini (Late 2012), I cannot update any Apple apps. When I sign in I get the following error message without explanation.
Every other non Apple app updated flawlessly with Catalina, but Apple apps, which should have no problems WITH THEIR OWN OS will not. Why?
Mac mini, macOS 10.15
Hi gjvall,
Thanks for reaching out in Apple Support Communities. I understand you're having trouble updating through the App Store and you're seeing an unknown error when you try to sign in. I can know how important it is to stay up-to-date; I'd like to help. I recommend using the steps in the following resource to troubleshoot this error, the title doesn't match your issue exactly, but the steps can help: If you can't connect to the App Store, iTunes Store, or other Apple services
I'd also suggest starting your Mac in safe mode and test to see if you can sign in and download updates: How to use safe mode on your Mac
Let me know what you find.
Best Regards.
