Why can't I move the first Desktop in Mission control? All spaces are moveable between each other except the first. Why?
The first desktop is considered the master all of others (more like the one ring of Lord of the rings ... One ring to rule them all) ...
For example, if you try changing the background on one of your desktops, it will only change for this one. Except the first one will change the background of all your desktops.
