So I hjave upgraded my SEPM to 12.1.4013 and pushed it out to my PC clients. I want to do the same for my MAC clients and i haver downloaded the install package from the Symantec website. I thne go to SEPM and choose admin-->install packages and click on add a client install package. I then give it a name and choose the zip file that i just downloaded. it then says uzipping the package and it then erros out saying out the specified zip file is not a valid MAC package. Only Mac packages can be added in *.zip format. Waht gives? Thanks.
You need to add the SEP_Mac.info file. It's located in the download ISO in the SEPM\Packages directory
