I also posted this in the support forums on Apple.com: Yesterday I sent an email to firstname.lastname@example.org with a fairly long and strongly worded complaint on behalf of 'old' Mac Pro owners about the 8800GT non-compatibility issue. I just received the following response: >Name withheld, > >I suggest you calm down. Everyone knows the issue and it is being >worked. > >Steve So, this is either from the big man himself (I have no reason so suspect otherwise), or from someone with enough authority to be able to personally respond to Steve's email. Either way that's good news. To receive even a brief message saying that Apple is working on it is certainly something that gives me a deal of reassurance, and hopefully we can all take his advice and calm down a bit.
