The new Mac beast puts me in mind of one of Dr Who’s Daleks.
Since the keynote I have been reading a number of blogs
and listening to many podcasts about this
and the general talk is the Mac Pro may have to ship
with ML 10.8 because 10.9 (Mavericks)
may not be ready for prime time.
Have to wait and see on that.
However if that is truly the case, it will be good news for C6.xx
Mountain Lion users.
That being said keep in mind that while more and faster power/connectivity
is a nice step forward and welcomed, (hardware)
like Lion and M. Lion:
THERE ARE NO NEW CORE MIDI OR CORE AUDIO IMPROVEMENTS
OR ENHANCEMENTS ANNOUNCED WITH OS 10.9. (software)
I do not see any advantages to Mac DAW users over the current
and the previous operating systems (10.7 or 10.8)
At least nothing Apple was willing to share with us at this time.
