Mac OS X 10.6.8 and Norton Family

I attempted to install Norton Family on my (old) macbook which I gave to my son after purchasing a new macbook for myself.

 

The installation went smoothly until I was prompted for the email address under which I registered my Norton account.  It would not accept my email address and prompted me to create a new account.  I ended up killing the install and rebooting.  Upon reboot, I tried to connect the computer to my Norton account - it asked for my email address and password.  I provided both but received an error message that I had an incorrect username/password combo.

 

I gave up on the mac for a minute and attempted to install on a PC running Windows Vista - no issues whatsoever.

 

I tried the macbook again - still did not work.  I initiated a chat and ended up speaking with a rep on the phone who told me that Norton Family is not compatible with Mac OS X 10.6.8, and that I had to upgrade to 10.7.

 

Really?  Please advise.
