I keep getting this message on my screen on my MacBook Pro which is running Mountain Lion.
I have tried going to system settings > Security & Privacy > Firewall > Firewall Options then pressing the minus button on Popup. But yet I am still getting this error message. Tried restarting my computer and its still there.\
Can anyone give me some advice on getting rid of this error message?
