Aperture 3 Performance Fix – Make Slow Aperture Run Faster


Just a quick tip to you Apple Aperture 3 users out there, who are experiencing a (very) slow running Aperture 3 – like I did. Mine was so bad, I was about to go crazy. It could easily take 5-10 seconds to make adjustments, and that’s just not good enough. I figured Aperture 3 was buggy, since performance did improve a bit when version 3.0.1 was released.

Then when 3.0.2 came and nothing was changed, I decided that something must be done. Luckily, I found a tip that solved my issues.

Thanks to Matthew Bergsma at the Apple Discussions board, my Aperture 3 is now running fantastic and fast!! He suggests that you first make sure to have done all necessary software updates, then delete all files in the following three folders:

Hard Drive/Library/Caches
Hard Drive/System/Library/Caches
Hard Drive/Users/(Your user)/Library/Caches

Also delete this file:
Hard Drive/Users/(Your user)/Library/Preferences/com.apple.aperture.plist

You might want to create a backup first, just in case. But there shouldn’t be any danger here, since we’re dealing with cache folders and a “settings”-file for Aperture 3 (you’ll have to modify settings again, if you’ve changed them in the first place).

Doing the things above and restarting my Mac, solved my Aperture 3 issues. I don’t know why I was suffering in the first place, it’s possible that it was because I imported my iPhoto library into Aperture 3, but I can’t say for sure.

If you’re not yet an Aperture 3 user, I suggest you check out the demo from Apple – you can also buy Aperture 3 from Amazon for less than $180.

  3. Just a quick heads-up. The following sentence…

    Also delete this file: Hard Drive/Users/(Your user)/Preferences/com.apple.aperture.plist

    …should read:

    Also delete this file: Hard Drive/Users/(Your user)/Library/Preferences/com.apple.aperture.plist

    …at least on my Snow Leopard MacBook.

    • Actually strike that.. (or moderate that!) it doesn’t.. you just have to open your exiting library because your preference for opening the last one is gone, so everything is there, you just have to open the library file.

      • Hi Joe,

        Yeah I wouldn’t expect Places and Faces to get nuked when clearing cache files – that wouldn’t make any sense ๐Ÿ™‚ Not sure about the settings (.plist) file though, I can’t remember if I lost any of my Faces or Places after doing this. Well, I’d rather go through my Faces again at high-speed rather than living with a “10-second per adjustment” Aperture from now on ๐Ÿ™‚

        Thanks for your comment!

    • I don’t know, sorry. I wasn’t aware there were any performance issues like this, with Aperture 2 as well.

  6. I seemed to have lost all of my photo’s I already had saved in Aperture when I did this. Can anyone give me instructions on how to get them back?
    Thanks!

    • Sorry to hear that, Lissa. That’s why I encourage people to have a backup first. Actually, everybody who values their photo should ALWAYS have a backup that’s not too old (max 1 week, I’d say, but the shorter the better).

      Your photos should still be in the “Aperture Library” folder though, located in your Pictures folder. You can right click it to view package contents.

  7. Haha thanks, I do have a backup but it’s about a week out and I did a bunch of work yesterday (of course!). Didn’t want to have to go there if I didn’t have to.
    Got the ol’library back – thanks so much for your help – this worked very well for me!

    • I’m glad it worked for you ๐Ÿ™‚ It would have been terrible if you had lost your photos in the attempt.

  10. Aperture is damn slow even after doing these steps. I have some 5000 photos and it takes ome 10 mins to load the thumbnails. Its just a shame to apple to realease such product. My mac book pro finder loads thumbnails faster then this shitty aperture. I think i will shift back to Lightroom.

  11. I started to follow the instructions, but balked when I got to:
    Delete Hard Drive/Users/(Your user)/Library/Caches

    That folder contained preference info on just about every application on my machine! So, I scanned the folder and deleted folder “com.apple.Aperture” (after creating a back-up of course!!)

    I followed the remainder of the instructions, and amazing difference.

    Aperture 3.0.3 has still hung up occasionally on one thing, creating a duplicate version.

    • Hi Alphonse. The /caches folder only contains cache files but of course there could be some cache files based on preferences too, but nothing will happen if you empty *that* cache folder. The actual preference files are stored elsewhere so if necessary, the apps will just make a new cache file based on the stored preferences.

      But I’m glad you managed to speed up your Aperture 3 anyway ๐Ÿ™‚

  13. Hey, hope this helps others … I made the jump from iPhoto to Aperture, and did the import. It brought all my pictures (of course) and all the data, like faces and places. But within a few minutes Aperture came to a crawl, it was ridiculous. We’re talking 15+ seconds when adding a name to a face. I googled and found this fix, and it has restored the speed, its like turbo-boosted.

    I’m new to Mac, I was a bit skeptical because I was going through the caches and the files I was deleting weren’t big, they were like 8kb.

    Seriously, so happy its back up to speed. thanks.

  19. Nice one sir. Aperture now behaving like it should. Can’t believe the difference although damn near soiled the pants when my old library didn’t appear until I added it manually.

    Excellent

  20. Before I attempt this solution, could someone please clarify exactly what settings will be lost/reset from deleting these files?

    Thanks,
    Edward

    • I don’t remember, sorry. The cache libraries are just caches, they will be rebuilt. The preference file, I can’t remember about – but just drag it to your desktop first, then you have a backup – and it’s deleted from its location as well.

  21. Nice fix. It run a bit faster afterwards. But it still is relatively slow. Its funny how the powerful processors & dedicated graphics on my Mac can’t help. Apple should take a serious look at this issues.

  22. Just wanted to say how grateful I am for this tip. I’d just upgraded from Aperture 2 to 3 yesterday, using a dodgy serial (so I could properly test), put was seriously put off a purchase by the fact that Aperture was taking, what felt like, a couple of minutes to start. Cleared out those caches, deleted the preference file, and startup time dropped to a couple of seconds. It’s now running faster that Aperture 2 ever did, so an upgrade purchase, I think, is imminent!

  26. Worked for me, too. Actually, my whole Mac is running faster. Thanks so much! I had been afraid to mess with anything, but the sluggish performance got me so frustrated I did a Time Machine backup, held my breath and went for it. I did have to reset my custom Command set, and tell it not to look for Faces (too slow). But it kept my custom presets and some other tweaks I’d made. Anyway, thanks for sharing this!

  27. LOL, I just came across this post on google while looking for information on why it seems my 9400m is running aperture better than the 9600 in my 08 macbook pro.

    Well, I’m glad this simple “user-land” fix to an oversight by the QA team is still helping people who are upgrading from aperture 2 now.

  28. Hey, I just wanted to take a minute to thank you for writing up this article. Your instructions literally turned Aperture from a burden to a blessing.

  30. Wow, I’m genuinely impressed. This actually worked! I can finally make adjustments without ripping my hair out. Not only did it speed up Aperture, but it’s helped a few of my other programs as well.
    Thanks a bunch for this tip!

  31. You just made my day! Thank you very much… i was just thinking about splitting my library or moving back to iphoto or whatelse…

    Now I’m just happy! =)

  35. Wonderful. So glad my search turned up your post! Aperture is now back to normal for me. Not speedy but then again neither is Photoshop on my system. No idea why after using for a couple of years it decided to crawl, but this took care of the problem. Thank you!

  38. Whaay! Great!! Have been trying everything, but this seems to work, at least for smaller libraries (max 5000 photos per library).

    Still have to check our biggest library (50.000+ photo’s). I am a bit afraid that this won’t perform, but I’ll keep you posted ๐Ÿ™‚

  42. Hmmm. It appears I don’t have/can’t find this library: Hard Drive/Users/(Your user)/Library/Caches

    Anyone know where I can find it?

    • Scott,

      Just open up a Finder window, then hit shift+cmd+G (“go to folder”) and enter:

      ~/Library

      This will take you to your user library (which is hidden by default in Lion – a smart move by Apple, most users never need to go there anyway). Then navigate to the “Caches” folder and delete the folder or the content.

  44. You don’t need to delete all chaches if you’re running OS X Lion. Just delete:
    1) “com.apple.Aperture” folder in “User/Library/Caches”
    2) “com.apple.Aperture.plist” file in “User/Library/Preferences”
    3) “com.apple.Aperture.plist.lockfile” file in “User/Library/Preferences”
