It seems that if I don’t use my MacBook often enough it punishes me by making a screensaver out of the macOS App Store. At least, that what it feels like, since it opens with an empty split-view scene and immediately goes into a blissfully restful state that shows me a spinning beachball until I Force Quit it. It also seems that this is one of the more widespread issues with macOS right now as there are hundreds of “how to fix” articles, which is ironic for something that Just Works.
In the most recent instance of this issue I found one workaround and one fix, so I’m making notes to myself:
- Seems you can update macOS via Terminal, with:
softwareupdate -i -a
- If you have an account issue – and you have no way of knowing that you do, so this is a “give it a try” fix – you can reset your default Keychains:
Go to the Keychain Access app, open the app Preferences, and select Reset my default keychains
If you try the fix you may want to reboot or sign in/out and some setting may have shifted but it depends on your setup and preferences. For me, I just rebooted, and viola! the App Store showed up fine and started taking updates again.
