Mac anti-theft trick

Found a hint that helps in case your machine ever gets lost or stolen, set the login to say:

"If you have found or purchased this machine, please contact Yourname at 713-555-5555 or yourname@email.com.  Reward for its safe return."

Using the OnyX software, go to the "Parameters" tab and then the "Login" tab below.  There you can customize your login message.  There's also other software that will just change the message without all the other fancy stuff OnyX does.

Definitely not foolproof, but helpful, easy, and free.
