Q: Aperture 3.4 will not open.

Deleting 'com.apple.Aperture.plist' allows me to open the application.  Muy Bad Apple. 

This is not what we were hoping for, a cryptic process required to fix a working application.

It worked for me to. Thanks.

Hi,

same problem here after updating to 3.4

none of the usual trash plist, use backup etc worked

at the end i deleted APERTURE, restarted Mac, redownload, start app, relink the library and it automatically updated library and all files

now fully working, no loss ;-)

JP.

I tried deleting the plist and Aperture did not load - still on 10.7.5

Here is the error message

Library not loaded: @executable_path/../Frameworks/PrintServices.framework/Versions/A/PrintServices

  Referenced from: /Applications/Aperture.app/Contents/MacOS/Aperture

  Reason: image not found

Don't delete the .plist.  Delete Aperture entirely.  Then re-install from DVD and update via Software Update to 3.4, or if you bought from the Mac App Store (way easier!) then just re-download it.

You should be good to go then.  It's not something easily solved by deleting the .plist; there's a corrupt framework inside the Application package itself.

This helped for me too!

I just deleted Aperture and reinstalled it from the App Store, nothing else.

Thanks!

I had the same problems and tried repairing the library etc. which all ended up crashing. So, I went to my user/library/Preferences and moved the file "com.apple.Aperture.plist" to the desktop and restarted Aperture and it worked. Hope this helps.

Had the same problem here on my Retina MBP.  Glad to find this thread and I moved the "com.apple.Aperture.plist" from "user/library/Preferences" to my desktop, and that did the trick.

That did it.  Thanks

Thanks fixed my problem.

Fixed for me too. Lets see how it goes next import...

ditto on the delete aperture and reinstall - thanks

Thanks a lot for your help. I finally found the com.apple.Aperture.plist file and deleted it. Now Aperture works fine

This is exactly what happened to me… crashed during upgrade, and then crashed again (several times) during "repair".

Deleted .plst and got it to work.

Is there any chance my images are corrupted? If so… How do I check?

This has not been the most elegant upgrade I have seen. I initially upgraded to 10.7.5 via software update and then to Aperture 3.4 via the App Store. Aperture would not start.

So I downloaded the 10.7.5 update from the support site and installed it over the software update version. I repaired permissions after the restart. I trashed the Aperture plist file as folks here have mentioned. Aperture would still not start. I trashed the Aperture app and reinstalled it from the App Store (at no charge obviously as the App Store knows I "own" it).

Aperture then launched although I had to tell it where my old Aperture library was and of course the library had to be upgraded to use 3.4. I also then had to reset my prefs as the plist file had been trashed. But at least it now works.

All in all a pretty "un-Apple" upgrade process. Did they hire someone from Microsoft or Adobe to manage the upgrades?
