Thank you Nat for the wonderful news. I am still working on the high resolution structure (1.3 Angstroms) with ~ 2000 residues. I use Mac only. With 64bit version I will be able to finish it
Some remarks:
a. Leopard is passe due to problems with X11 (probably not related to Phenix), so don't bother. Who knows what cat version is in the barrel of APPLE. It will be out soon (information).
b. Changing versions of Python may brake other applications.
c. thank you for making this brave step to 64bit Mac 
d. we will wait ;-)
