Ctrl + Alt + Delete on Windows provides a variety of functions, the main one of interest being the Task Manager. Is there an equivalent keyboard shortcut & indeed Task Manager for carrying out such tasks as quitting an application that maybe "hanging" (amongst other things) for Apple Macs, or indeed anything similar ?
There is no all in one equivalent:
The equivalent of the Windows Task Manager is The Activity Monitor app.
The equivalent of Close Session or Shut Down are found in the Apple Menu.
The equivalent of Change Password is the Users pane of the Configuration app.
The equivalent of Lock Computer is "Login Window..." under the User (your user name) menu.
Alt/Option-Command-Esc to force applications to quit.
For Task Manager style stuff Activity Monitor is it by default and its not key invoked.
You could attach a key combo in preferences to Activity Monitor
Preferences -> Keyboard -> Shortcuts -> App Shortcuts -->
Menu Title: whatever
Keyboard Shortcut: You key combo.
You can use
Activity Monitor and create a global keyboard shortcut to it via BetterTouchTool.
If you just need to lock your computer quickly, you can press:
Control ⌃+Shift ⇧+Eject
Edit: Unfortunately, one of Apple's OS updates killed the above key combination for no good reason. So the only key combination available now is this less convenient one (if you have a Mac Mini or an iMac you have to press the physical Power button on the computer in addition to the other two keys in the keyboard):
Control ⌃+Shift ⇧+Power ⌽
see http://support.apple.com/kb/TA22781?viewlocale=en_US That is the answer to Ctrl + Alt + Delete on a PC.
Ctrl + Shift + ESC gives you the task manager. This solved my problem. Credit to: https://discussions.apple.com/thread/3718443?start=15&tstart=0
