Do you have wxpython and/or wxwidgets installed through brew? There are currently issues when its both installed on the system and embedded in the bundle which are still being worked on. If you do have it installed in brew and are using The nightlies can you try moving the python folder thats inside the kicad.app/Contents/Frameworks folder (to python.old for example) and see whether the issue still occurs
