MacOS Builder Flake #496
Description
The MacOS builder has been flaking quite a bit recently, usually the Python 3.11 to 3.13 build on MacOS 13. I don't know if this affects MacOS 14 since the rest of the jobs get cancelled when this happens (those runners might also use different hardware).

It seems to actually fail in moviepy when trying to read a video:

The command output looks normal so I'm not sure what the issue is here, or why an OSError is being raised.
I suspect the exception is being raised here: https://github.com/Zulko/moviepy/blob/master/moviepy/video/io/ffmpeg_reader.py#L910
