Adeona is a tracking system unlike what you normally see. It doesn't have a proper interface, and the process is a little technical, but Adeona will efficiently track a computer for you. If you worry that your laptop might get stolen, then it's a good idea to set it up.
The first time you launch Adeona you'll be asked to provide a password. The program will then save your data in a file. Retrieving information is a little bit more tedious, but requires this first step to have been completed.
You can closely monitor the location of a laptop, requesting a start and end time and the number of items you need. This gives you an idea of where your laptop has been in a period of time.
Adeona essentially works via a term file, which launches the Terminal, so you are highly encourage to have at least some knowledge of the Apple utility to work with Adeona.
It's clear that this solution is not for everyone. If you have the patience and the knowledge you should find Adeona useful. Less experienced Mac users should turn to a simpler solution.
