Woe to those who receive cryptic messages on their Macs. “Click accept on the account page to update this app” is one of them. Which apps? Which account page? AIEEEE! (Picture Cathy here with frizzy hair, tongue sticking out.)
Turns out that this is an easy problem to resolve, and it comes from a place of corporate generosity. Apple makes a number of apps free to macOS users, some of which were paid at one point. This typically affects iMovie, Garageband, Keynote, Numbers, and Pages.
MacOS still registers and downloads those apps via the Mac App Store, and ownership can apparently get muddled even if don’t recall using multiple Apple IDs or copying the apps across computers. It can also occur if you Mac is serviced and the drive remains in place but the motherboard is swapped.
