Title is pretty descriptive!
It seems like there is a problem with my MacBook Air (2015), so it can't connect properly to iCloud. This means I can't do any software updates, open the App Store, etc. I can't log out of iCloud either, and when I tried creating a new user to fix the problem I couldn't log into iCloud.
Any ideas on how to fix this?
