Every time I open Aperture since the update I've had problems. Vaults not completing updating. Application not even opening. Thumbnails not displaying. Imports hanging. Databases needing repairing. Every time Aperture opens. Aperture now hangs on really simple tasks, and the more I have to update and repair the library database, the more worried I get about the safety of my files, especially as since the update none of my vaults have managed to complete without crashing. I can't work like this - I'm now importing into Capture One Pro, so I can get on with my work. This is the first time that I have had to move from an Apple product because I'm questioning the reliability. It can't be just me? INfo : This is on a 27 iMac i7 3.4, with 24 GB RAM. I don't think it's my set up.
