My desktop background will not change from solid blue, even when I choose a different one. Its as if my macbook thinks I actually have a photo there, but its not. Has anyone dealt with this before?
MacBook Pro, OS X El Capitan (10.11.2), 2011
1. If the desktop picture always reverts to a plain blue background, one of your login items may be causing the problem. The "TeamViewer" application can have this effect. Otherwise, rule out all other third-party login items as possible causes.
2. If you have a MacBook Pro with automatic graphics switching, disable it temporarily in the Energy Saver preference pane, set the Desktop picture, then restart the computer and re-enable graphics switching.
3. If none of the above applies to you, proceed as follows.
Back up all data.
Triple-click anywhere in the line below on this page to select it:
~/Library/Application Support/Dock/desktoppicture.db
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. Log out or restart the computer and empty the Trash.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You may not see what you pasted because a line break is included. Press return.

Ciao.
Deleting the System Preferences settings file will obviously have no effect, as you already know if you did it.
Thanks! This worked for me.
