I got a Mac Mini from Apple, and tried to install NAV 11.0 for Mac from a purchased CD, since the OS is 10.6.8. The installer asked to install Rosetta, I said yes, and then completed the installation, ending with restart. Upon return to desktop, this error message starting popping up, and returned again every time I dismissed it: "Norton Antivirus Error: Norton Antivirus Auto-Protect could not continue. Please run LiveUpdate or reinstall Norton Antivirus and restart. (Code: 10)". When I tried to run LiveUpdate, Update everything (in between dismissing the repeated pop-ups of the error message), I got this error message: "Updating error. There was an error performing the update." When I tried to open NAV itself, I got this error message: "Norton Antivirus could not open its preferences. Please try restarting your computer. If this error persists, please try re-installing Norton Antivirus." I have tried multiple restarts, and two reinstalls, with no improvement. I found one suggestion to do a "Get Info" on the NAV application, and uncheck "Start in Rosetta". Box was already unchecked, so I checked it, tried a restart, no improvement, then unchecked it, tried a restart, no improvement. Symantec clearly says the NAV version for 10.6 is 11. Help?!?!
