Unrecognized file type error

Hi! When I double click on .3dm file in the Mac finder I get an Unrecognized file type error. I can open the same file using File>open in Moi. I downloaded a fresh copy of Moi, but get the same results. I am using MoI 3.1 and OSX El Capitan.

Does anyone know how to fix this so I can once again open files from the Mac finder?

Thanks for the help!
