The problem that I am experiencing (and many others like me as I have noticed in several fora) is that the "source" when selecting an image screensaver blocks at "loading" while nothing happens and no (folder or aperture library) source can be selected. The problem started basically since Apple blocked the possibility to use a folder with images in subfolders as source for a screensaver as used to work perfectly in Snowleopard. But while Mountain Lion only works with iPhoto or Aperture libraries it made the system susceptible to windows like errors.

 

When selecting a slideshow-screensaver, the source remains as "loading" where no options are given to select anything. It used to work until a few months ago, but I have no clue why it stopped or how I can get it to work again. When the slideshow screensaver is selected I get an error message telling me there was an error connecting to a netwerk server. No clue why it actually needs that server (which died some time ago). If i shutdown systempreferences while the slideshow is still selected, each time it tries to start the screensaver I get the same warning that there is a problem connecting to a (dead) airport extreme.

 

I have tried to reinstall Mountain Lion, rebuild a new Aperture image library, remove certain .plist files that may be connected to this as was suggested in several fora, nothing works. I cannot imagine that Apple forces me to abandon Mountain Lion and to go back to Snowleopard over a screensaver.

 

A hint to third party developers: please create a simple slideshow screensaver where you can select a folder including subfolders. It can't be that hard to create (although Apple fails completely).

    First follow the instructions in this support article.

    If an iPhoto or Aperture library is the source of your desktop pictures, it may need to be rebuilt, or you may need to update the application to the latest version.

    Otherwise, continue as below.

    Back up all data.

       

    In the Finder, hold down the option key and select

      

    Go Library

      

    from the menu bar. From the Library folder, delete the following item, if it exists: 

     

    • Caches/com.apple.systempreferences

     

    and move the following item to the Desktop:

     

    • Preferences/com.apple.desktop.plist

     

    Launch System Preferences and test. If you still have the issue, put the item on the Desktop back where it came from and post again. Otherwise, delete the item.

    Thanks for the suggestion. I hadn't come across this one yet. But unfortunately there is no change in the problem. Still nothing other than the source in screensaver showing "loading". Do you have other suggestions?

     

    I had already built a completely new Aperture library just to find out if that was the problem... but that wasn't either.

    Launch the Console application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

     

    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

    View Show Log List

    from the menu bar.

     

    Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V).

    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.

    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.

    I feel it's coming close to the cause of it:

    what's the next step?

    (thanks again by the way)

  • Linc Davis Level 10 Level 10 (153,370 points)

    Back up all data.

    Triple-click anywhere in the line below on this page to select it:

    ~/Library/Preferences/com.apple.iApps.plist

    Right-click or control-click the line and select

     

    Services Reveal

    from the contextual menu.* A folder should open with an item selected. Quit Aperture and iPhoto if they're running. Move the selected item to the Desktop, leaving the window open. Test. If there's no change, quit again and put the item you moved back where it was, overwriting the one that may have been created in its place. Otherwise, delete the item you moved.

    *If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select

    Go Go to Folder...

    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

    The end is definitely near.... but not quite yet.

     

    This does help in the way that after removing that specific file, I can select a map to use as source for the slideshow screensaver. Unfortunately this doesn't work with subfolders since ML. Thus is the Aperture library necessary, but none of the iPhoto or Aperture folders can be used. And after starting Aperture again, the original problem starts over again (until I move the ~/Library/Preferences/com.apple.iApps.plist file again).

     

    Aperture thus causes the ~/Library/Preferences/com.apple.iApps.plist file to currupt itself and none of the iPhoto and/or Aperture libraries were available to select.

     

    what's next?

  • Linc Davis Level 10 Level 10 (153,370 points)

    I don't use Aperture so I can't test, but it sounds to me like you're triggering a bug. There are a couple of discussions of this issue with ideas that you might find helpful:

     

    Aperture Library unavailable in Desktop Background

    Desktop pictures

  • freudsigmund Level 1 Level 1 (0 points)

    I've just done a test with iPhoto which I use as well for a different photoset and the result is the same:

     

    it works after removing the ~/Library/Preferences/com.apple.iApps.plist file, then after starting iPhoto the trouble starts all over again. So it's not just Aperture and since Aperture and iPhoto trigger the same bug. Odds that both apps are corrupt in the same way are very slim, and it must therefor be that the cause lies elsewhere... the question is where. Could it be that iLife (whatever that is) could be the cause?

  • Linc Davis Level 10 Level 10 (153,370 points)

    None of the suggestions in those threads helped?

  • freudsigmund Level 1 Level 1 (0 points)

    unfortunately not. they;re all very specific for issues in Aperture only, not for my problem where iPhoto and Aperture are causing the problems in iLife or whatever causes the screensaver to crash.

    Please read this whole message before doing anything.
      
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
       
    The purpose of this test is to determine whether the problem is localized to your user account. Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
       
    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
       
    Test while logged in as Guest. Create a photo library by downloading some images from the Web or importing from the folder /Library/Desktop Pictures. Same problem?
         
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
      
    *Note: If you’ve activated “Find My Mac” or FileVault in OS X 10.7 or later, then you can’t enable the Guest account. The "Guest User" login created by "Find My Mac" is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.

    In the guest account everything worked exactly as it should... what does this tell you?

  • Linc Davis Level 10 Level 10 (153,370 points)

    Problems such as yours are sometimes caused by files that should belong to you but are locked or have wrong permissions. This procedure will check for such files. It makes no changes and therefore will not, in itself, solve your problem.

    First, empty the Trash.

    Triple-click the line below on this page to select it, then copy the selected text to the Clipboard (command-C):

    find ~ $TMPDIR.. \( -flags +sappnd,schg,uappnd,uchg -o ! -user $UID -o ! -perm -600 -o -acl \) 2> /dev/null | wc -l

    Launch the Terminal application in any of the following ways:

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.

    Paste into the Terminal window (command-V). The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.

    The output of this command, on a line directly below what you entered, will be a number such as "41." Please post it in a reply.

  • freudsigmund Level 1 Level 1 (0 points)

    The number is 185
