Apple - Ctrl + Alt + Delete: Mac Equivalent?
The keyboard shortcut you’re looking for is ⌘ + ⌥ + ⎋, alternatively known as command + option + escape. This will bring up the Force Quit Applications window (see screenshot below).
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.
To complete previous answers :
- The shortcut control-eject brings up the shutdown/reboot confirmation dialog (I use this a lot : you just have to type control-eject then enter to shutdown. Very handy!)
- Pressing cmd-shift-Q brings up the quit session confirmation dialog.
