Apple has pushed out GarageBand 6.0.4, introducing a few minor changes in addition to the usual “overall stability and performance” fixes. Of note, GarageBand’s Lesson Store has been changed to fix an issue that was preventing lesson downloads from completing properly. On a more practical note, the update also addresses a bug that caused some tempo-based effects to fall out of sync with the main song, as well as a problem with Magic GarageBand projects not opening properly in the tracks view. ($14.99 new from the Mac App Store, free update through Software Update or the Mac App Store, 53.72 MB)
