Minna, As I point out regularly on the mailing list, I am not a Mac user and do not maintain the mac packages. You really need to inquire on the mailing list for support in that area -- that way you will actually find the people who *can* help you. Here are some recent threads on the mailing list regarding Mac installation issues: http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2009-September/009018.htm... http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2009-October/009077.html Perhaps your answer is there. If not, please feel free to make a new request for help on the list. Here is more information about the resources available to you: http://cars9.uchicago.edu/ifeffit/BruceRavel/FormLetters/HelpRequest As I explain there, the mailing list should always be your first stop when you have a question about the software. B PS: If any of the Mac users out there would like to update the Macintosh Issues section of http://cars9.uchicago.edu/ifeffit/FAQ/Installing_Ifeffit that would be really splendid.

Hello Bruce,

I'm trying to run Athena on a Mac, OS X Version 10.6.1. Following the instructions at cars9.uchicago.edu/~ravel/software/downloads.html#mac for a Macintosh OSX download, I went to SourceForge to download Ifeffit. The latest version does not appear to be available for Mac download, so I grabbed Ifeffit-1.2.10.1-Mac10.4_Intel_horae66.dmg<http://sourceforge.net/projects/ ifeffit/files/ifeffit/1.2.10/Ifeffit-1.2.10.1-Mac10.4_Intel_horae66.dmg/down load> , because I'm on an Intel Mac, but the installation failed. I then grabbed Ifeffit-1.2.10-Mac10.4_PPC_horae066_pkg.dmg<http://sourceforge.net/projects /ifeffit/files/ifeffit/1.2.10/Ifeffit-1.2.10-Mac10.4_PPC_horae066_pkg.dmg/do wnload> and the installation appeared to work, but when I went to run Athena, X11 opened but nothing else happened. I'm not really sure what the problem is - can you at least give me a suggestion on where to start?

Thanks for your help!
