Upgrading SEP client for MAC OS

Hi,

We upgraded our SEP Infrastructure of 3500+ clients from 12.1.4 to 12.1.6 MP5. First we upgraded SEPM and then SEP clients(Windows). We upgraded clients by assigning upgrade package to different groups in which clients reside. We have some MAC OSX clients left that needs to be upgraded. Can anyone guide what are the options for upgrading MAC OSX SEP clients?

Thanks.
