Q: iPhoto slow since update.

What is your OS version, and what version of iPhoto do you have??

First, ensure you create a back up.  If you use time machine, I would recommend you create a current back up. 

How much free space is available on your hard drive?  If you are low on space, this can cause this issue.

Once your back up is in place, do the following:

- restart the computer

- ensure all software is closed when you get back to your profile

- in the top menu bar, select "go", then "utilities", then "disk utility"

- in the left column, select "Mac HD", then click once on the button, "Repair Disk Permissions"

- once done, launch iPhoto

- if the issue persists / quit iPhoto

- hold down your "option and command keys", and click on the iPhoto icon in the dock, while continuing to hold down the two keys

- this will make the iPhoto "first aid" appear

- start with the first repair step, and go through them all, until you either resolve the issue, or get them all done

- let me know how that works for you

Try this....

Quit all open applications

in the top menu bar, click "go", then hold down your options key are your keyboard.  When you have the options key held down, you will see a "library" appear under "home".  Select this library, then go to the preferences folder.  Here, look for two files, and drag them out to your desktop:  These files are:

com.apple.iApps.plist and com.apple.iPhoto.plist

Then, go back one screen, and open the "cache folder. Here, drag one file to the desktop:

com.apple.iPhoto

Close all windows, and test out iPhoto

You need to be in Finder, to see "go" in the top menu.  Quit all open windows, so you only have your desktop viewable.  The word "Finder" should be beside the apple.

Did you verify that your version of iPhoto is up to date?  You should be running iPhoto 11 version 9.4.2 to be completely up to date.

Also try seeing if this issue is specific to YOUR library, or not. 

To do this, open up iPhoto, then file / switch to library.  In the window that opens, click the "create new" button in the bottom.  This will create a new blank iPhoto Library.  Import an image into this library, and try to publish it to facebook to see what occures. 

To switch back to your original library, simply go to file / switch to library and select your original library.

Repair Disk Permissions messages you can safely ignore - http://support.apple.com/kb/TS1448.

As you have already done all the iPhoto First aid steps, you can do the following:

          - if you use Time Machine, we can restore from a time machine back up

          - you can seek out a 3rd party software, which has additonal tools to attempt to rebuild your iPhoto Library called iPhoto Library Manager

Using iPhoto Library Manager to Rebuild Your iPhoto Library

1. Download iPhoto Library Manager and launch.

          2. Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.

          3. Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option

          4. In the next  window name the new library and select the location you want it to be placed.

          5. Click on the Create button.

Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

Your Welcome

That's a common error message others have encountered when repairing permissons in Lion and is not significant.  You can ignore it.
