I'm at work sans Poser, but I can do some more debugging as soon as I get home this afternoon. I was just beginning to sort out the code last night, but I was running a bit low on concentration - too sleepy.

Quote - Is the ScriptsMenu folder somewhere different on mac?

Nope, it's exactly the same path to that folder.

Quote - that "should" be saying find the location of poser.exe or poserpro.exe and build a path adding Runtime:Python:poserScripts:ScriptsMenu

I didn't specifically check the results of this assignment, but I'm almost certain it's working correctly. The extra 'ScriptsMenu' level is being added to the path after building the menu tree, but before trying to execute the activated menu item. I'll track it down.
