i don't think that will work, because macos installation is done via
disk images.

what you can do is to create a directory $HOME/vmd-plugins and then
add to your .vmdrc file this line:

vmd_plugin_scandirectory [file join $env(HOME) vmd-plugins] *.so

this should load the plugins. watch the VMD startup messages.
