MacAlarm is a free MacBook and PowerBook alarm application that alerts users when their device is moved. SMS notifications to a specified phone number are also available. AMSTracker is required in the Applications folder.
In addition to the automatic movement sensor, you can also add another layer of security with an SMS notification. Simply specify a phone number to receive an alert if the alarm goes off. This feature can provide you with an extra level of protection and help you locate your device quickly in case of theft or misplacement.
One thing to keep in mind is that, before using MacAlarm, you'll need to have AMSTracker installed in your Applications folder. Once you have that set up, however, this app is straightforward and easy to use. Overall, MacAlarm is an excellent option for anyone looking for a free alarm application that can help keep their laptop secure.
