Hi all... Does the Mac App Store only check for updates to installed applications only ? Since i have an external drive, with a backup app on (the game is BiosShock 2) an do keep a backup on external so i won't have to redownload the 18Gig or so file later on... However, everytime i plug it in i get an update to this despite it not being actually installed at all.. Apple tells me Software update is assosiated with your Apple ID, however when checking i am NOT signed in. yet the update it there.. unplug external drive and re-check, update disappears... "No software updates available" I do have other game installers on external, however, its probably the only one that has an update. To me though, I thought Software Update only checks for actually installed software.... not any software it finds on any attached drives. This would be like downloading OS X Yosemite installer, waiting for the next iteration, and Mac App Store finds it as an available update despite your not even using Yosemite. Any way to fix this ? Hiding updates it not possible since it does appear even when not signing in. Tried another user and same thing.... Apple informs me the only way would be just to delete it.. If true, then this would be more of a "we want to to keep stuff in the cloud only" otherwise u may have issues like these.... Its the only conclusion i came to.. Anyone else experience this ?
