I pick up an upgrade copy of Aperture 3 at the Apple Store last night.
Installation was a greater chore than I anticipated. Aperture crashed consistently on startup. A little googling revealed that this problem is widespread amongst upgraders. The solution was to delete the Aperture ProID file from Library/Application Support. After restart I needed to enter the serial of my previous Aperture install (Aperture v2).
After start-up, Aperture 3 took 2+ hours to update 70,000 thumbnails in my referenced photo library.
Once I had Aperture 3 up and running I had one additional crash that took down the whole computer, requiring a reboot. Fortunately I did not loose any work. In fact Aperture opened up to the same window with the same images selected prior to the crash
So far I’m happy with the features. I geotagged an entire Bali/Wakatobi trip very quickly. I just hope we see a stability update soon.
I'm learning not to be such an early adopter. I waited until this week to update the OS from 10.5.8 to 10.6.2. I was too anxious to wait for Aperture 3.1.
