Well, if you are banking on OS X as your platform for scientific computing, it seems you have chosen very poorly. I still don't understand why an organization would choose Mac Pros for workstations. That seems to me to be a class of machines where price/performance is very important, and Apple hasn't been very competitive in that area.
I think Apple has done a pretty good thing today. They've politely signaled to the market that they want you to f' off and buy someone else's product in this segment, because you aren't worth the effort anymore.
The money is in iOS and the laptops. And you don't need more than an iMac to develop for iOS or the laptops, so they just can't be bothered to make a workstation anymore. If you are pissed off about this you should investigate Linux or Windows.
