Opening files with multiple versions of Rhino

Hi, I’m having troubles with opening files on Mac. Currently I have 3 versions of Rhino installed: Rhino 5, Rhino 8 and Rhino 9WIP. When I double click any .3DM file it automatically opens Rhino WIP, which is the version, that I’m using the least. I just want to test some new features from time to time. So I quit it instantly and it’s really annoying…

Is there a way, how to open v5 files in Rhino 5, v8 files in Rhino 8 and v9 files in Rhino WIP?

Thanks.

i normally mark special files that should be worked on with special versions with rhX
for example:
FilletSrfPlay_00_rh9.3dm

as far as i know, you can map one file extension only with one programm.
get a info from the file (right mouse botton or cmd i)
there is a open with
→ change all
or set to a specific programm.

theoretically it should be quite simple do a kind of "3dm- launcher / branching / dispatcher app that uses

and send the file to the correct version of rhino.
