Apple Event: May 7th at 7 am PT
Ever since I installed Mountain Lion my desktop picture keeps resetting to a solid color. I can change the picture to the one I select. Then after restarting the machine or logging in after a logout the picture is gone and just reset to a solid color. I see a few people having this issue. Any tips?
TIA
MacBook Pro with Retina display, OS X Mountain Lion
The desktop background is controlled by the options supplied with this command:
defaults write com.apple.desktop Background
which is at the heart of the script. Basically, it sets up the option for that across all 'spaces'. However, it works even if you have only one space.
I note that some people have tried removing the com.apple.systempreferences.plist with temporary success. That suggests to me that you're all running some other 3rd party software (possibly the same one, but not necessarily) that is corrupting the plist file or resetting the Background option.
The trick is to find out what is doing that. It's likely to be some utility like MacKeeper or some hidden process you've set up that is running on a schedule. Pathfinder can also cause problems with deskop background settings under certain conditions.
You need to go through a process of elimination to find out where the problem lies. Start with getting some useful system info by using this free little diagnostic tool written by etrosoft, another ASC member:

Post the results here if you're not sure what you're looking at, and I or someone else will try to take you through the steps of what to do next.
Not sure if this is new info, but I had a development with this issue I thought I would share.
I recently reinstalled Mountain Lion on my MBP. The desktop background issue was gone. I was thrilled! Then I turned file vault back on and now the issue is back! I am curious as to how many people having this issue have File Vault turned on. Thoughts?
TIA
everytime mine resets I do this and it has worked, just do exactly as the instructions say
open terminal and paste rm~/Library/Preferences/com.apple.Desktop.plist
press enter
log out and log back in
change your wallpaper
log out and log back in again, should fix it, it works for me and I have done it a few times now
