If you purchase this software and install it on your Mac in hopes of being able to trace your stolen computer. Keep this in mind if someone steals your computer and erases the hard drive they also erase the LoJack software and your computer will not be traceable.
I purchased this software for my son's MBP 2010 thinking I would be able recover it if stolen. It's been 3 months and no trace. The software needs to be installed in the computer's system Bios to be traceable.
