ModLauncher.app doesn't work on the current Steam version. It crashes on start saying
dyld: Library not loaded: @rpath/libIL.1.dylib
Referenced from: /Users/xxxx/Library/Application Support/Steam/steamapps/common/SOMA/ModLauncher.app/Contents/MacOS/./ModLauncher
Reason: image not found
Abort trap: 6
I tried to copy all libraries from Soma.app/Content/Frameworks to ModLauncher.app/Content/Frameworks but lo luck anyway - it crashes instantly after start.
