I just got an email from mcafee the other day saying mountain lion is supported in the latest update
I installed the latest updates a couple days back and it does work on Mountain Lion.
That's kinda not my problem though. The problem I have is that it does not support the Retina MacBook Pro hardware or Macbook10,1 is the official hardware code.
The other MacBooks that have upgraded to Mountain Lion are fine but it's the new batch that I bought that's not supported.
I have exactly the same issue with the Retina hardware. I raised a enhancement request shortly after the product launch but am yet to get a response.
