Most Affordable Theft Software For The Mac? In Case Someone Steals It..

[Raima]

Best solution is to create a custom 200 pound concrete case around your imac, then bolt the two peices together. Also booby trap it so if the concrete ever gets unbolted it sets off a self destruct sequence. That will be sure to deter thieves!!

some signs like this around the house

and some barb razor wire might deter some thiefs too
