Thanks Camilo! You're absolutely right that it needs python and TK with those options. Sorry that I forgot that. That being said, it should not have installed pymol without those packages. I suggest you run brew update before installing. Also, if you run brew install tk --enable-threads it should automatically install TCL with threads too.

Best,

Hi all

This option to install pymol is great!. However, I tried to install it in my 10.8.2 with xquartz intalled and it was crashing. 

For it to run well, you need to enable threads, do:

brew uninstall tcl
brew uninstall tk
brew uninstall python
brew install tk  --enable-threads
brew install tcl  --enable-threads
brew install python --with-brewed-tk

Dear all,

We just got pymol into the popular package manager for OSX, homebrew. To install pymol on with brew, just run the following two commands ("%" stands for the shell prompt and should not be typed in:

% brew tap homebrew/science
% brew install pymol

That's it, you should be on your way to using pymol soon after the installation finishes.

Also, this installation switches the stereo/mono graphics paradigm. Recent builds of OSX with intel chips seem to crash with stereo graphics. Therefore, pymol defaults assumes the "-M" flag has been passed to it. You can switch to stereo graphics (if you know it won't crash your computer) with the "-S" flag. Alternatively, you can install pymol with original stereo graphics on as default by installing with brew install pymol --default-stereo

Hope this helps bring pymol to more people!

Best Regards,
Derek Thomas
