Komodo Edit on Mac and RhinoPython
Komodo Edit can be configured to recognize the rhinoscriptsyntax module which provides for editor features like autocomplete and function tooltips.
- Download and start Komodo Edit – http://www.activestate.com/komodo-edit
- On the menu, select Komodo->Preferences…
- Expand “Languages” and select “Python”
- In the Additional Python Import Directories click on the “add” button and navigate to
/Users//Application Support/McNeel/Rhinoceros/MacPlugIns/IronPython/settings/lib - Click OK, it may take a minute for Komodo Edit to parse all of the files and generate autocomplete information, but once that is done you should be able to type your Mac Rhino python scripts with a little help from Komodo!!
Steve Baer's Notes 
Could you kindly update this post ? I tried to do it exactly like you’ve done it here but did not get anywhere. When I open komodo edit and start typing it doesn’t provide suggestions. Or if possible you could direct me to where I can find more info about it as I’ve been searching for a while now !
