I tried this to see if it was really easier and better than 10.5.6's own firewall tools for a "noob" to use. I stuck to the "recommended" settings suggested in the software. After giving it the go to change my settings, I found that I could no longer connect to the internet. I undid my changes using the program, saved them, uninstalled the program, double-checked my connection settings using back-up snaps... physically reset my modem... and rebooted my computer... but nothing worked.

For the first time ever, I was stuck with a glaring red stop light on my long trusty modem,
which always had reset easily and smoothly.

I tried Apple's built-in configuration assistants and they determined that everything was a-okay. Everything except my connection to the internet. The assistants worked feverishly but finally gave up and suggested that I contact my ISP for support. Unfortunately the only expedient way to contact them would have been on the internet. And that wasn't happening.

Since I had been planning to upgrade my computer soon anyway, I finally gave up and switched computers. My connection was automatically reset.

Needless to say, this is one program that this noob (who's used all sorts of computers for decades and has happily maneuvered the web since '94) will NOT be installing on his new computer.

Try it only if you understand everything you're doing every last step of the way and don't have to trust the program's recommendations. In fact, it's probably a good idea to cruise through the whole program without changing anything, to ascertain you understand it completely before changing anything. Otherwise you have been warned!
