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
Q: Desktop background stuck in solid blue
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.
Try deleting the System Preferences plist. Use these instructions:
