You should just put this:
https://github.com/marcoc1712/squeezelite-R2/releases/download/v1.8.4-(R2)/squeezelite-R2-osx
somewhere in your system give correct permission to it and run it.
I downloaded this exact file you mention. It downloaded as .dms
Remove the .dms extension and make it executable by running "chmod a+x
~/Downloads/squeezelite-R2-osx" in the terminal window (make sure you
pick the right path, should it no longer be in your downloads folder.
