Yeah that's what I suspected. Unfortunately mbpros have many other issues with Linux, if they even have drivers at all for the new ones. As far as nvidia they won't budge so Redhat going in on a technology that isn't supported by a large majority of its user base seems a failing on their part to me. Then again, I don't think they care much about desktop Linux so I can see where they are coming from focusing on server products and the minimal ui needed to occasionally run a gui rather than something one could use every day like os x or even windows. So much for the Linux desktop.
