Hi, Overall, the transition from 10.6 is seemingless, crystallographically-wise.
Of course you need to have the new XCode 4.1 installed, and you should also download new, 10.7-dedicated 64bits gcc/gfortran/g77 bundles from http://hpc.sourceforge.net/ And then, CNS, Phenix, CCP4, etc... will just run perfect. I had to reinstall Coot -- but that's minor. (Mac)Pymol also works fine, yet (for some reason) uses a lot of resources even when idle. As per the Upsalla Soft. Factory programs, you'll have to recompile then using the above mentioned bundles, or get already compiled binaries from Mark Harris. You'll also need to recompile Gromacs (and fftw3) if you're using it -- but it then works great. I agree with W. Scott on the fact that the new OS is really greedy in terms of resources. I surely wont upgrade my other, older mac computers that run just fine on 10.6. But if you have a new Mac, Lion is is really neat.
