Juli Clover, Macrumors:
Apple recently removed older versions of OS X and other discontinued software from the Purchased tab of users who had previously purchased or downloaded them. With the change, it is no longer possible for users to download Aperture, iPhoto, OS X Lion, OS X Mountain Lion, and OS X Mavericks from the Mac App Store.
Even if my beloved Aperture weren’t mentioned, this is still disheartening. And it’s not just the Mac App Store. Panic:
We’ve seen this too. iOS removed-from-sale apps, like Prompt 1, may be unavailable for re-download as well.
This might all simply be a misconfiguration or a mistake, but I’ve long been worried something like this may happen. This is software that was previously purchased; while it’s no longer available for general sale, it should still be offered to those who purchased it to download again. I certainly hope this isn’t a deliberate change.
