Hi. I got some problems. Before upgrading to 10.8 I added two folders (let's say A and B). These folders are now not removable for me. I click the "-" and they disappear but once System Preferences is relaunched they are present again. Code: System Preferences: Could not restore selection, using default folder Is listed in Console.app for every time I remove A or B. I already deleted the corresponding .plists: ~/Library/Preferences/com.apple.desktop.plist ~/Library/Preferences/com.apple.systempreferences.plist ~/Library/Preferences/ByHost/com.apple.screensaver.* But after a restart of Sys Prefs the files reappear - with entries for folder A and B! There has to be some default setting for SysPrefs but I don't know where. Even editing the plist files directly and changing the values will be ignored. Adding a new folder works but only the last one added persists (others disappear). I tried starting System Preferences as root for the case there would be some missing write permissions but without success. I got no clue what to do next. :/ Whenever I change ~/Library/Preferences/com.apple.desktop.plist it will be overriden when System preferences is relaunched. Removing rw permissions for everyone editing the .plist by hand does not help, too. The changes will be ignored.
