Hi Jonathan, re: copy/paste between OSX Rhino and OSX MoI - I just tested this with the most current Rhino OSX release and it seems to be working fine for me over here.

Just make sure that Rhino is running when you do the copy from MoI, if Rhino is running MoI will do some extra work to put Rhino format stuff on the clipboard for pasting into Rhino. If Rhino is not running, MoI will only put MoI-specific stuff on the clipboard.

Also Moi does not read some kinds of things that Rhino has like lights, polygon meshes, or block instances. If you've got block instances explode them first before trying to copy/paste them from Rhino into MoI.
