PyVol missing MSMS and cant find it (reoccuring issue)

[BDGrows]

I keep getting the same issues as others using Pymol when attempting to get pyvol to work. I had to go as far as using the program on Ubuntu in order to get it working. Any suggestions on how to fix this?

I have had the same issue with a Mac OS. Did you get back from the author? @rhs2132 @schlessingerlab

I also had the same issue on Mac OS. And I cannot download msms with conda, so I chose to download it manually.
Firstly, I downloaded msms package (Mac OS (Mojave and after)) manually on the website https://ccsb.scripps.edu/msms/downloads/.
Secondly, on a Mac OS, double-click to unpack it and go to /Downloads/msms_x86_64Darwin_2.6.1/. In this directory, the execution file of msms is /Users/user-name/Downloads/msms_x86_64Darwin_2.6.1/msms_x86_64Darwin_2.6.1
Thirdly and importantly, we should add this path of execution file to the environmental path of PyMOL. For Mac OS, the command as follow:
sudo ln -s /Users/user-name/Downloads/msms_x86_64Darwin_2.6.1/msms_x86_64Darwin_2.6.1 /Applications/PyMOL.app/Contents/bin/msms
Finally, it's ok!
