Our shop has multiple Macs. One iMac Pro (Mojave) does not show the available updates in the Updates pane of the App Store application. You have to manually go to each app in your account and individually click the update button for each.
Automatic updates are disabled (like on all of our machines), since I want to control the timing of any updates. All of the other Macs show when any updates are waiting, except this one.
Is there a cache that needs to be reset or some standard way to get the behavior to function correctly? Zap PRAM? Other?
