Use Different Desktop Background Pictures for Spaces in Mac OS X Lion
Assigning different wallpapers to different desktop spaces is much easier in Mac OS X Lion, here’s the quickest way to do this:
- Enter each space individually
- Right-click on the desired background image and choose “Set Desktop Picture”
- Repeat for the next desktop space
Using this method and Mission Control to switch spaces is the fastest method, but you can also do this through System Preferences.
Before Mac OS X 10.7, third party utilities had to be used to set different wallpapers to each virtual desktop space, making this another nice addition to Lion.
