Desktop & Screensaver preferences pane not storing changes
Okay, I've seen this issue mentioned in other discussions for older operating systems:
My Desktop & Screensaver preferences pane is not storing changes made to the "Folders" section in the left sidebar.
If I add a few folders to the list, they remain until I quit System Preferences. After restarting System Preferences I'll generally only see one of folders that were previously added. After that first change, I can remove all folders, replace the existing folder with different folders, anything really. Then once I quit and reopen System Preferences, I'm back to seeing that one folder from the first time I went through the process.
I initially tried to remove all .plist preference files related to System Preferences, Desktop, Screensaver, and Display settings, but nothing changed. This reset the settings, but as soon as I added folders back into the list, the issue reproduced itself.
I've confirmed the issue occurs in a second, brand new user account.
I tried repairing permission and repairing disk via Disk Utility.
I reset ACLs via the Password Reset dialog in the Recovery utility.
Any other ideas as to how I can resolve this issue? Is it a bug?
