3y3.net (http://www.3y3.net) has introduced The Logger 1.0, an US$19.99 computer monitoring tool for Mac OS X (10.5 or later).

The Logger records what your employee, roommate or child does on you computer. The software utility records every key pressed in your Mac and takes a snapshot of the screen with every mouse click detected.

You can even receive an email every time a keystroke session is started. The Logger creates full HTML reports for every session where you can see all keys pressed and snapshots taken.
