It should be compatible now assuming your version has updated recently requiring a reboot. For those who obtain the software through 3rd parties, ISP's, PC makers etc., that may not have happened because they hang on to new versions for a while and in some cases for an unreasonable length of time.
Unfortunately there is nothing that McAfee can do about that.
