Is there any other information you need?
This crash I believe is fixed in the master version of Kivy, can you check?
Also you should consider upgrading to the SDL2 providers, pygame has been deprecated at this point in time.
[INFO ] [Kivy ] v1.9.1 [INFO ] [Python ] v3.5.1 (default, Apr 18 2016, 11:46:32) [GCC 4.2.1 Compatible Apple LLVM 7.3.0 (clang-703.0.29)]
I can't find any related issues on the kivy project.
I'll try SDL2 providers
In order to try a master kivy you must clone from github and install from source. Either that or wait for the next release.
You were right the problem is caused by pygame.
I used kivy setup.py build_ext install instead of python setup.py build_ext install
to be sure the installation goes to the Kivy.app which is the recommanded osx install and this one is bundeled with the SDL2 lib instead of pygame.
Just a note here also: There is another issue also The
[ERROR ] OpenGL Error (FixedVBO.update_buffer-glBufferSubData) 1281 / 501
stuff is fixed by:
https://github.com/kivy/kivy/pull/3970
but this has not been merged yet
