SEP Mac OS 10.12.6 Sierra Install

Hi All

We currently run Symantec Endpoint Protection 12.1.7 RU6 MP5. We are trying to install a SEP client onto Mac OS 10.12.6 Sierra, and we are getting incompatible version of MAC OS X.

The package installer we have on the SEP Management Console for Mac is 12.1.6867.6400. Is there a newer version for our version of SEP, or do we have to update to Symantec Endpoint Protection 12.1.7 RU6 MP6.

Or is this version of Mac not supported with 12.1.7 and we will have to go to 14 ?

Thanks
