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).

Move your photo library aside and create a new, simple one as you did in the Guest account. Test.

Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.

This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.

 

Step 1

If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.

Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):

{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null

This time you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.

 

The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.

Step 2 (optional)

 

Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.

Boot into Recovery. When the OS X Utilities screen appears, select

Utilities Terminal

from the menu bar. A Terminal window will open.

In the Terminal window, type this:

res

 

Press the tab key. The partial command you typed will automatically be completed to this:

resetpassword

 

Press return. A Reset Password window will open. You’re not  going to reset a password.

Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.

Select your username from the menu labeled Select the user account if not already selected.

Under Reset Home Directory Permissions and ACLs, click the Reset button.

Select

Restart

from the menu bar.

You could try rebuilding the existing library in Aperture or iPhoto. Back up first. If that doesn't work, you're in uncharted territory and I don't know what else to suggest. Maybe your library is too large for the screensaver to handle.

 

Rebuilding the iPhoto library

    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.

    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?

    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

    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?

    None of the suggestions in those threads helped?

  • freudsigmund Level 1 Level 1

    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.

    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

    The number is 185
