APERTURE 3.3 GENERATING THUMBNAILS

It's most likely a bug.

Have you upgraded to 3.3.1?

My largest Library required 110 hours of processing time to regenerate all thumbnails and previews, after which it was missing about 25% of the images. I am currently repairing that Library.

It's a bad show by Apple, but the only alternative I see is to restore a pre-upgrade Library, and then upgrade that Library after installing 3.3.1. I may still do that -- I'm waiting to see what the results of repairing the finally-finished-being-upgraded Library are.

Quit the application and restart. See if the count on generating thumbnails decreases, than you might be good once the process has been completed. In my case it always starts again even after it has been finished once. Really annoying. I hope, there will be a fix soon.

I just wanted to confirm I see exactly the same behaviour. 7000+ previews generated every time Aperture 3.3.1 launched. No matter if preview generation is ON or OFF (not in the preferences, not in the LIbrary view). *****!

huskyte,

in your case it might be a case of a corrupted user preferences file, this can cause Aperture to start over and over again, because it cannot write to the file.

Have you tried to remove the Preferences, as described in Aperture 3: Troubleshooting Basics, Delete the user preferences, ?

If not, try that after quitting Aperture.

Thank you, I tried that before and just now as you suggested. No difference. Constantly, 20-30 seconds after launch Aperture begins generating 7000+ previews.

Just reporting back that uninstalling and reinstalling Aperture did NOT help! So it's Aperture 4:0 Jan 😟

I already tried the following:

1) Uncheck "Generate Previews for new Projects" in Preferences

2) Turned off "Maintain Previews for Projects" for all my projects

3) Trashed Aperture plist file from Library

4) Clean reinstall of Aperture

The bloody 7000+ preview generating thing comes back EVERY time I launch Aperture!

Heeeeeelp!

Yes, I submitted the bug report to Apple as well.

Hi Leonie,

thanks for the help. This time a permission repair did the trick. Usually it doesn't help, but I am happy to report that I have restarted Aperture three times already and no reprocessing occured.

Just wanted to update - no solution yet.

1. I have now deleted Aperture completely with ALL preferences and traces one can find on the OSX (In ~/Library/Preferences ~/Library/Application Support)
2. I rebooted the iMac
3. Ran "Repair Permissions" and "Verified Disk" - all fine no issues
4. Installed Aperture 3.1 (that is the install dmg I have)
5. Ran Update Software and updated to 3.3.1
6. Opened my Aperture Library
7. and again got 7800 previews generating
8. I allowed it to finish, closed Aperture
9. Launched Aperture - generating 7800 of those same previews again
10. Closed Aperture, launched it holding Option+Command keys and set it to Rebuild the Library

Nothing, I constantly get this issue of Aperture generating 7800 previews. It must be a bug.

Just a quick addition, last night I let Aperture finish the generation of the 7000+ previews. Then let it run. The iMac went to sleep mode and when I woke it up this morning, Aperture began generating the 7000+ previews again. Definitely a BUG! So not even a relaunch is necessary!

I just created a new Library. Then imported the old Library into it. Same behavior. When launched, generating Previews as before. 😢

Thank's again to all who chip in. I have now done the following:

Restarted iMac into Lion Recovery Mode and Verified and Repaired Disk - there were no issues at all.

I then restarted the iMac and Repaired Permissions (via Disk Utility) - no issues found

Then I copied my referenced Library to my brand new MacBook Air (less than 10 days old). When I launched it all went well, no Preview generation, no matter how many times I launched it. BUT! Since my Library is referenced I then loaded the HDD in my iMac (via Finder) where the originals (masters) reside and launched Aperture. All went well. I clicked on some photos and choose "Show in Finder ...". Finder showed the original on my iMac drive. Then I closed Aperture and as it was closing, it not only shared previews with iLife as instructed in Preferences, it also popped second pop-up "Upgrading Library ..." Then it closed.

I relaunched Aperture and it almost instantly began generating 7300+ previews.

Then, I ejected the HDD in my iMac via Finder on the MBA. Closing down Aperture (on MBA), it again Updated the Library. Relaunching Aperture resulted in NO preview generation.

I did the same exercise on mu iMac (I have 256GB SSD with OSX, apps and Aperture library on it and I have 2TB HDD in it). I ejected the HDD, closing Aperture, it automatically "Updated Library". Relaunching Aperture without the HDD loaded (so Referenced Library without the originals available) resulted in no Preview generation. Rebooting iMac and having HDD load up again brought the behavior back!

Go figure. At least I know reinstalling OSX is not necessary.

After my last post I realized that the reason for the behavior above is because the HDD in my iMac goes to sleep when the iMac does, so it probably appears to Aperture as if it was being disconnected and reconnected. It appears that the bug has to do with dis/reconnecting of the originals to referenced library.

Opening up Console on MBA shows the below, any ideas? (I filtered for Aperture in the search field of Console)

Hey There, Had the same issue after updating to 3.3. I think I fixed it by doing two things.

1) Select all images in the library, and "Update Preview", it may take a while depending how many. I had about 60,000 images in RAW. I did the process over night and it had finished by morning.

2) "Rebuild the Database" - hold down "option" and "command" while opening Aperture. This step may take a while however I have had to do it twice, once before for another issue, it seemed to finish in a few hours. Keep an eye on the "Activity Monitor" and watch that it is processing (you can watch the reads and writes) it may say "not responding" as long as it continues to make the reads and writes let it go.

I used referenced files, as opposed to letting Aperture Manage the files. Also, I have a Quad Core i7 iMac with 16GB's RAM. My images reside on an external 3TB Seagate Drive connected by Firewire 800.

I was reluctant to do it, but the Apple Support person told me the only other suggestion was to delete all the previews and regenerate. I figured it would take days with 60,000 images so I went this route. It has been a week now and all seems fine.

I have 8 more LIbraries teh same sive that are "Managed" to upgrade to Aperture 3 and I am reluctant to do so until I need the images for something...

Good Luck!!
