The default is also for "any application", make sure to keep this set. Tell the new service that it receives "no input" (rather than the default of "text"). Launch Automator and create a new service. If mousing to part of the screen isn't your thing, you can use the keyboard to lock the screen, but it takes Automator (or a third-party application, but Automator is the better bet if you're using OS X 10.6). To use the mouse to quickly lock the screen, choose Start Screen Saver and select which corner you want to use I'd suggest either the bottom left or right corners to avoid accidentally triggering it when using the menubar. There are a few options: enable screensaver, disable screensaver, and put display to sleep (amongst others). button that, when clicked, allows you to define which corner of the screen you can mouse to in order to engage the screensaver. At the bottom of the pane there is a Hot Corners. To do this, in System Preferences, go into Desktop & Screen Saver and select the Screen Saver tab. If you're a heavy mouser, then enabling one of the screen corners to be a "hot corner" to enable the screensaver might work best. If you use Windows or Linux, this shortcut is extremely different and possibly difficult to remember if you are not used to it, but luckily OS X makes it easy enough to make it something more memorable. Once this preference is enabled, you can use the CTRL-SHIFT-EJECT shortcut to start the screensaver. This would largely depend on your needs and whether or not you have a short idle timeout (which is defined in the Energy Saver section of System Preferences).
#IS THERE A CONTROL ALT DELETE FOR MAC PASSWORD#
You can specify a timeout as well, so that OS X will only require a password after the screensaver has been active for a minute, or five minutes.

Under General, enable the Require Password After Sleep Or Screen Saver Begins. To enable requiring a password when the system has started the screensaver, start System Preferences and go to the Security section. Unfortunately, while OS X has this capability, it is not enabled by default.
#IS THERE A CONTROL ALT DELETE FOR MAC MAC#
For a Mac to be considered as secure as Linux or Windows in the work place (or by anyone that values their privacy), making it so that a quick keyboard combination locks the screen is an absolute must.


On the Mac, however, there is a rather strange keyboard combination that will blank the screen (CTRL-SHIFT-EJECT), but by default does not lock the screen. With Windows, hitting CTRL-ALT-DEL engages the screensaver and locks the screen. With Fedora, and most other Linux distributions, hitting CTRL-ALT-L by default will engage the screensaver and lock the screen.
