Ok, I have Leopard installed on my Mac Pro.
Quick and simple to do, and seems to operate just fine!

However, my main application, Hauptwerk won't
release a "Leopard" compatible version until later in
November.

But, I still have the previous OS, Tiger, installed and
operating just fine on a separate HD, along with
Hauptwerk. Only constraint is that no more than 4GB
of data can be used in HW, Tiger is 32-bit. Thus the
desire (need) for going to Leopard and the full 64-bit
RAM use. Several of the larger pipe organ pipe sample
sets use much RAM, up to 8 and even 10 GB (thus why
I had been using XP-64 in my previous AMD powered PC).
The author of Hauptwerk is now "urging" the use of the
Mac because of the wonderful MIDI handling of that system.

I have Leopard installed to a separate HD in the Pro. But,
when HW is made available for OS X 10.5, there will be
no special reason to maintain Tiger on the separate HD,
and Leopard could also be installed on that drive.

But should I? Or what else can I do with a second internal
HD? (I do have an external HD which is the "Time Machine's"
houly/daily/etc., so that takes care of the need for file, system
back ups). Cannot go to some kind of RAID set up, UNLESS
I erase both internal HDs completely; don't really want to
loose all that programing I have done for particular organ
sound systems -- took hours!

Thanks for comments, Jim
