Seems like cpu_affinity is not available on macOS: https://github.com/giampaolo/psutil/issues/1826, likely we need some fallback option

Hi Nick, Thank you for letting me know the error and the link. I confirmed the error, and the fix will be included in the next release.

Best regards, Jake

In the meantime, I'm releasing v24.2.0 binary for macOS with this fix in a few days.

Hi Nick, You can download v24.2.0 from baramcfd. This version has the fallback you said. Thank you.
