I want to make movie from my molecular dynamics simulation outputs. Pymol was suggested to me, when i read its tutorial, i noticad that it is more usefull for mac systems.
For most tasks, PyMOL works equally well for MacOSX and Windows, only for some quite advanced stuff where PyMOL has to directly collaborate with other programs, you have to either use Linux or Hybrid PyMOL, which is closer to the UNIX kernel of OSX.
The main difference in movie-making is that for better control of movie size and quality, it is better to export the movie as a series of PNG pictures and to use an external program to convert these into a movie, rather than export as an MPEG or Quicktime movie. On MacOSX, you could use Quicktime for this, on Windows, there are other programs with which I am less familiar.
Sadly, current versions of PyMOL under the free educational license no long support ray-tracing, therefore for best quality rendering, you would either need to get the incentive version, compile the open source version yourself, or find a precompiled version of the open source version on the web. (http://www.ld.uci-edu/~gohlke/pythonlibs). If you can let me know how to best get some rather large files (30MB) to you, I can send you the slides and demo files for the 3-day PyMOL course I am teaching, students in that class are free to use either Windows, MacOSX or Linux, PyMOL works fine on all three.
