So there's this great hidden feature of OS X that allows you to set your screen-saver animation as your desktop background, but it is a Terminal command and it requires Terminal to be running in order to continue executing it. Here it is: Code: /System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background So the million-dollar question is → Does anybody know of a way to keep this running even after you quit Terminal? Yeah I know, it's a waste of CPU cycles and battery power... but my Mac is plenty fast and is a desktop machine so I'm not concerned about that. So how about a Terminal command to made the above Terminal command not require Terminal to be open in order to continue? Any ideas?
