This review was originally posted on VersionTracker.com.<br />Ok, I had this running on my Powerbook, but upgraded to 10.3.7 and now it doesn't work. Furthermore, after doing research, all you have to do in order to defeat this is to change the memory configuration on the computer, and *then* zap the PRAM. Thanks alot. Is there anything that can actually secure my machine short of having to lock it up physically? Sheesh!
