California based iZooLu LLC today announces Lock Desktop 1.0 for Mac OS X on the Apple Mac AppStore. Lock Desktop will secure your Mac Computer and return you to a login screen. It allows you to switch between users from the login screen and applications and data continue to run on the other desktops. Leaving your applications and data safely locked behind your username, Lock Desktop is just what the Windows Switchers and die hard Mac Addicts have been looking for.
