PowerBlock intercepts presses of the power button and optionally runs an AppleScript. This is handy on the MacBook Air where the power button is now a key on the keyboard and can be accidentally pressed.

By running an AppleScript when the power button is pressed, you can setup your system to immediately shutdown, restart, sleep, or eject a DVD. This is great for headless servers.

Known Limitations: PowerBlock does NOT prevent a hard shutdown if you hold the power button for more than 4 seconds.

What's New

  • IMPROVED: Inform user when there's an error in the AppleScript.
  • IMPROVED: Hide the splash screen by checking "Hide" in System Preferences > Users & Groups > Login Items.
  • IMPROVED: 1024x1024 application more...
