Ah yes that will be the problem then, There is current efforts being made to work around this issue, but its not something that will be working soon Unfortunately the workarounds prior to that are not pretty, and mostly consist of not having a system wxpython install It will mainly require removing the usage of wxversion.py as that does not work nor is it designed to work with bundled libraries as yeah it breaks stuff (well documented as such) so wxversion.py is only useful on linux. There is also efforts going on to bundle the entire python runtime as recommended by apple for applications that require python, so this should also help. > On 21/11/2017, at 12:59 AM, Brendan Simon
