Nope, still getting the same error. The call to modules.cv2win32.show_preview in get_previewer() is still unguarded. It's also seems a bit scary to catch assertions... The gist also doens't work out-of-the-box for me, I get this:

Exception in thread Thread-2 (worker):
Traceback (most recent call last):
  File "/Users/rho/mambaforge/envs/fooocus/lib/python3.10/threading.py", line 1016, in _bootstrap_inner
    self.run()

    self._target(*self._args, **self._kwargs)
  File "/Users/rho/git/Fooocus/modules/cv2win32.py", line 12, in worker
    cv2.waitKey(50)
cv2.error: Unknown C++ exception from OpenCV code

I just removed the calls to close_all_preview() and show_preview(), and then it works great (albeit without previews). See an old branch (pre 1.0.16) at https://github.com/rickardholmberg/Fooocus/tree/rickard/run-on-macos
