IMac Dual Core owners take note!, 2006-03-03 I'm not sure this product deserves a "one star" rating because I was never able to use it. Since none of what came with my new computer mentioned the built-in firewall, I thought I needed one. Wrong. After trying to install the program with no success, I finally checked Symantec's website and found the problem. Amazon won't refund opened software but Symantec will for this problem. Still waiting for my refund.....
