The App Store icon in my Dock always has a little "1" badge on it indicating that 1 app is available for update. That 1 app is "Remote Desktop Client Update 3.7.1" via "Software Update."
However, when I click either "Update" or "Update All," it seems to update, but the "1" badge doesn't go away and the App Store perpetually shows that the Remote Desktop Client is always available for update. FYI: I have two Macs and this problem happens on only one of them.
Why is this the case? How can it be fixed?
