First Apple release Aperture 3, i'm happy as Larry jumping on the band wagon to upgrade. I really wanted the facebook, flickr and video support. Little did I realise what a painful experience would be. It didn't warn me about not having enough disk space (I didn't) it complained something about FS error and crashed before you know it it deleted my entire Aperture library. None of the file restore applications would pick up the lost files due to the amount the intense reading/writing and moving which happened just before it deleted the library… I lost 2 nights in Hong Kong and 2 days worth of photos in China because of this. I learnt my lesson, no more upgrading without proper backups and no more trusting jobs! I do want that iPad though...
Now there should never ever have be a branch of the code where this is even permitted to happen! Come on testing 101!
Now Apple releases an update to Aperture 3 which presumerbly fixed most of the issues I had only to have the update program not detecting Aperture 3 properly, dear God! Apparently this was an issue they have had before from the upgrade process of Aperture 1 to Aperture 2. Is there no process at Apple to manage these historical blunders? FFS!!! Apple!
Delete the following file from Library > Preferences:
That's the file the 3.0.1 updater is checking and then revealing the incorrect Alert! message. Apple had the same problem with 2.0, and history seems to be repeating itself.
