I am unable to setup this package while using the Select button for selecting the Aseprite.app folder, which is located at ~/Library/Application Support/Steam/steamapps/common/Aseprite/Aseprite.app.

Got it to work, the correct file is at ~/Library/Application Support/Steam/steamapps/common/Aseprite/Aseprite.app/Contents/MacOS/aseprite. Finder on OSX doesn't allow opening .app directories so the finder selector won't actually work on selecting the right file, I had to use my terminal to figure out the binary location.

Ok. Thanks for reporting. My personal problem is that I don't have a Mac to test and thus probably miss some obvious solutions. I will keep this in mind.
