I updated my iPhoto to 9.4.3. When I ran the application, and slided some photos. I noticed that the movement wasn't as smooth as before, evenmore iPhoto lagged sometimes. Does anybody in here have the same problem? It annoys me when I want to slide some photos in a succession. If others don't have the problem, how can I tell Apple? I am using 13-inch Macbook Air 2012 model. Thank you for your attention

MacBook Air, OS X Mountain Lion (10.8.3)

    How big is the HD? How much free space on it?

    My Macbook Air has Bootcamp, 225 GB for Mac OS and 25 GB for Windows. On the Mac OS, I still have 114 GB of free space

    What do you mean by "slided some photos"? Do you mean swipe between them? Or make a slideshow of them?

  • afternoonbyrobin Level 1 (0 points)

    Yes, I apologize for my bad english. Yes, I swiped some photos, and It didn't move smoothly. I didn't take a slideshow or make a slideshow. Just, swiping. I am sorry for my english

    No problem I just want to be sure I understand.


    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.

    Well, I am quite confused. Which one is the best between 4 choices avaiable? The problem is I can't swipe smoothly. So, Should I rebuild thumbnails only or database? I am really sorry, I am not a long user of Macintosh and iPhoto

    Use the resulting dialogue to rebuild.


    As TD said, use the fourth option: "Rebuild Database", and don't forget to backup your iPhoto library before you do it.

    Apply the fix below: 


    Fix #1


    Launch iPhoto with the Command+Option keys held down and rebuild the library.




    Since only one option can be run at a time start with Option #3, followed by #4 and then #1 as needed.

    Thank you for all your concerns and helps. I tried to apply the fic, but until now It hasn't been better. It still lags. I remembered, when I downloaded for this update, The download failed for 3 times. Would this affect my iPhoto? I mean, because The download failed, It might corrupt some of the files. Thanks, I appreciate all your helps and concerns

    It is a possibility.


    But before you reinstal, check if the slowness you are observing is caused by your iPhoto Library, the settings in your account, or a system wide problem.


    • First of all, how full is your harddrive? If it is getting too full, less than 10GB free or so, multi media applications like iPhoto will slow down.
    • Do you see the same slowness, when you are using a different iPhoto Library? (create one for testing, if you only have one library).
    • Do you notice the same slowness, when working from a different user account (see: Isolating an issue by using another user account)


    If iPhoto not lagging, when browsing a different library, your current iPhoto library is causing this; maybe you have a corrupted image or video in your library.

    If iPhoto does not work in your account at all, but from a different user account, your preference file may have become corrupted.

    If iPhoto does not work in any account, try safe boot mode: Mac OS X: What is Safe Boot, Safe Mode? and test iPhoto there.


    Post back with your test results.
