I have downloaded an installed Aperture Inspector 1.2. Then I dragged my Aperture Library on it and let it run. After one night I still saw the spinning wheel and the message that it is reading the Library file. My library is 7,23 GB. I quit the program and restarted. Now it is running for another hour and the wheel keeps spinning. Is this still OK? I'm on a 2,6 GHZ i7 Macbook Pro. Thanks for your advice.
