Summary
This fixes an issue preventing pyModeS from being usable on OSX. The root cause of the issue is that the default start method for multiprocessing on OSX is
spawnwhich is not compatible with pyModeS. Additionally, as of Python 3.14forkmust be specified explicitly. See: https://docs.python.org/3/library/multiprocessing.html#contexts-and-start-methodsThere's probably a better way to clean this up however this is the simplest fix for now.
