Mac App Store bug allows iWork trial users to update the entire suite for free (Update: Aperture, too)
Users who have previously downloaded the free 30-day iWork trial and kept it on their systems found themselves able to update to the latest version of Apple’s productivity suite for free yesterday due to what is apparently a bug with the way the store finds copies of the software purchased through other sources.
Since the Mac App Store now detects boxed copies of iWork and allows them to be updated to the Mac App Store version, it seems the trial versions of Pages, Numbers, and Keynote are perceived by the App Store as being a full purchased copy. This allows users to install yesterday’s updated apps without having to pay anything.
