PlugSpy 2.3

Plug Spy is a first-rate tool to observe your Mac. It activates automatically on-screen lock and triggers actions in case of unexpected occurrences. Instant notification on your phone will give you additional security if you leave your Mac alone.
Instant Protection to Catch a Thief
Plug-Spy lives in the OS X system menu, ready to observe your Mac. Select one of the Action-Sets and you are done. Plug-Spy will activate its sensors' on -screen lock and trigger actions based on predefined rules.
Doing It Your Way
Action-Sets are based on sensors, user-defined rules, and resulting activities. No matter if you want to know who is waking your Mac or entering a wrong password in your absence, Plug-Spy can trigger actions based on your requirements.
Sensors and Actions
Sensors currently available are observing the MagSafe adapter, computer power-state, connected screens and login window. Any sensor activity can result in an alert sound, iSight snapshot, local notification, a Boxcar or Pushover message to your phone, or a post on Twitter.
