Moved to Mac and Linux Products for a faster response - Moderator
Actually, I'm not sure this is the right spot, are you using the retail/consumer version or a commercial/Enterprise one?
If you are using the consumer product and having problems with that please read this thread: Support for "McAfee All Access - Internet Security" in Mac OS X Yosemite?
But please indicate if you are so I can move this out of the Business community.
McAfee Security has been superseded by McAfee Endpoint Protection for Mac. The latest version, 2.2 is supported on OS X Yosemite. There is also a dependency on the underlying McAfee Agent 4.8 version as well. An updated version of the 4.8 agent is required for McAfee EndPoint Protection for Mac 2.2 on OS X Yosemite.
I would suggest working with your McAfee account team to see if EPM is available under your product grant.
