Cannot Update App
Just bought a new iMac and it's prompting me to upgrade GarageBane, Keynote, Numbers, Pages, and iMovie but when I try to do that I get:
Cannot Update App
<app> cannot be updated because it was refunded or purchased with a different Apple ID
I've logged on the the App Store but don't see any option to "adopt" the apps that came with the machine. What's the trick to resolving this?
