Hi ,
very embarrassing

Now I can start to try to debug.

Thank you for pointing me to the rules. Tried to set your answer as the correct one... did not get the menu point

I've downloaded the R20 SDK on my Mac
renamed to python.app and renamed the bin to phyton as documented in the SDK docu
installed PyCharm

• preferences
• project interpreter
• add
• system interpreter
• navigate to /Applications/MAXON/Cinema 4D R20/phyton.app/Contents/MacOS/phyton
• ok

==> invalid python interpreter nae 'phyton'!

Any idea how to get that fixed?
