“This whole thing is why many of us are upset about the possibility that Apple is dropping the MacPro.”
Sorry to go off topic…
Just speculation, but if Apple does this, I would not be surprised to see them license Mac OSX to select high end PC workstations. No technical reason why this can’t be done, now that Apple is using Intel.
It allows Apple to abandon creating hardware that is not profitable enough for them, without abandoning a market where their OS has a large presence. A win/win as far as they are concerned. As long as they keep it officially limited to select high end workstations (firmware or some other restriction), it won’t diminish the brand. Hackers will get around it, but they are doing that anyway, as the thriving Hackintosh community already exists.
Would never happen if Steve were still around, but Cook has already stated he is open to doing things differently.
