Hi Pilou, no the Obj to 3DM converter program is for Windows only right now.

It's probably possible though to copy the converter program inside of the MoI OSX version wrapper and then run it under the same Wine system that MoI uses to run. To do that, right-click on the MoI app and choose "Show package contents", and unzip the converter program under the "drive_c" directory that is inside there.

Then to launch it, do the same "Show package contents" again and then double-click the Wineskin.app that shows there, go to "Advanced" > "Tools" > and push "Command line shell" - a command prompt window will pop up that accepts DOS commands, and the converter program can probably be launched ok from that command prompt. I did not test it myself yet though.
