The question being is, What suite of McAfee Protection do you have, and is it a Active Subscription?
Normally one would remove from their computer before installing on another. Do you by chance have a (3) license or more Subscription?

The only PC products that can be used to some extent on a MAC are "All Access" or "LiveSafe" otherwise one of the suites specific to MAC's has to be purchased.
See the product page here (top and bottom sections): Antivirus Software, Virus Scan, Internet Security Protection | Home and Home Office Store | McAfee.
Thanks everyone. Not sure I really need virus software on my Mac. Guess I will just let it lapse. Was hoping I could just "exchange" it for a Mac version since I still have six months on my membership. My guess is they won't do that. Thanks!
