The hits just keep on comin'! Last week my Aperture library was corrupted and I had to restore some files from a backup and delete some preference files to get it to work again. Now I'm having a new problem....
Aperture 3.3.2 launches and I get the "Opening Aperture library" window, but it never progresses to the usable application. Only a Force Quit allows me to try again. Launching Aperture while pressing the Option key allows me to select a different library (I set up a "dummy" library just for this purpose) and once the application is open, I choose File>Switch to Library>Other/New... and pick the main library, which then opens without further complaint. I can initially choose a dummy file on the same external hard drive as my main library, or I can choose a dummy from the Mac's hard drive—either one allows me to successfuly launch the application and proceed to opening the main library.
If I then quit the application and immediately attempt to re-launch it, the same thing happens again. I need to use the alternate library to launch, then switch from the active application.
I can switch to the alternate before quitting the app and it remembers the alternate library as the new default. It will then launch fine to the new default (alternate) library. At that point I can quickly switch to the main library.
So, I know the problem must be in the main library, but I can't figure out why it will launch successfully only after opening a different library.
I repaired permissions and rebuilt and repaired the database, but none of these seemed to fix the problem I'm having.
The new version of Aperture (v3.4) is out and this issue appears to have been fixed. My copy now launches without hanging. I hope everyone else is able to upgrade and enjoy the application again.
