It is necessary to convert an unmanaged Symantec Endpoint Protection (SEP) for Macintosh client into a managed client.
Export communications settings (sylink.xml) from the target client group within the Symantec Endpoint Protection Manager (SEPM), then copy it to the Desktop of the Macintosh you wish to make managed.
The SyLinkDrop tool is installed with the SEP 14 for Mac client in the /Applications/Symantec Solutions directory.
The SyLinkDrop version used must match the SEP for Mac client version. This is due to differences in the SEP master service that SyLinkDrop tries to restart after replacing the sylink.xml.
For all versions of SEP, you may also manually place the sylink.xml file into the appropriate folder on the Macintosh client computer per the following instructions:
SEP 14.2 RU2: /Library/Application Support/Symantec/Silo/MES/SMC
SEP 14.2 RU1 MP2 and older: /Library/Application Support/Symantec/SMC
NOTE: there are multiple Library folders on Mac systems, the correct one can be found in Finder>Go>Computer in the computer's hard drive.
From Terminal command line:
sudo launchctl unload /Library/LaunchDaemons/com.symantec.symdaemon.*plist
sudo launchctl load /Library/LaunchDaemons/com.symantec.symdaemon.*plist
