Error on OSX

Hi, on the last OSX version 11.6 on Intel, I made a clean install of Python, Cython, and PyMadCad. I tried running the sample program (here in github) and I get this error ( the same file works fine on Ubuntu) Thanks in advance Marc

Hello again @granludo ! glad you found your way to this issue tracker

And no window showing at all I bet ? This could be a duplicate of #33, can you check that ?

yes, I move to that discussion, sorry
