Thanks both. I have multiple physical sites. Only one SEP Manager is installed on the main site. So, Mac devices in other sites would not be able to get updates. What is your experience of allowing Mac devices to get updates from Symantec LiveUpdate servers? We do not have a huge number of Apple devices. Not sure whether it can cause network slow down.
Another question is some article says that LiveUpdate cannot update policies to Mac devices. How do Mac devices to receive policies in the first place? Or I got wrong information.
Thanks for your help again.
