So new i5 Air and immediately after setup the App Store icon in the dock shows that there are updates for the pre-installed iPhoto, iMovie and GarageBand. These updates do not show when doing a regular Software Update and if I download the updates via apple.com they refuse to install telling me I have to update via the App Store. When I try and download them through the App Store I get prompted that "You must have previously purchased the item being updated, tap buy to purchase it now" which obviously I don't want to to as I don't need to purchase the app. I'm a little unclear how I'm supposed to update the apps that are pre-installed if the App Store shows updates but won't let me download them? Anyone had the same or have any idea how I get around this please? Thanks.
