So I have found that on some of my iMacs I cannot access the FIREWALL section of the 'Nortons Internet Security' that is installed on my machine.
I want to basically check the settings and configuration... The current user experience is such that when I open up the Nortons Internet Seciruty it has the 3 service option (icons ( for Antivirus / Firewall / Vulnerabilities... when I click on Firewall its like it highlights but then the window never opens up. So effectively I cant see any of the settings information about 'incoming and outgoing connection blocking' etc.
I have made sure I am accessing with full Administrator rights on the iMac... so that is not what is limiting me to see/change settings.
