Clients running Norton AntiVirus 11.0.3 cannot be managed by the Symantec Administration Console for Macintosh.
Norton AntiVirus 11.0.3 will now provide vulnerability protection along with antivirus protection to client machines that the software is installed to.

An update to Symantec AntiVirus for Mac customers is being prepared at this time with a release scheduled as soon as possible .

Why is there a delay between the availability of Mac OS X 10.6 and Symantec products becoming compatible with the new Mac OS?
The final version of Mac OS X 10.6 was not made public until August 28, 2009 and it is necessary to test and ensure compatibility with this new operating system. This process requires a period of time. Please check back regularly for updates...
