The last Mac OS that had drivers for those was 10.10. Someone may have a workaround to get them working, but not officially supported.

"Qualified with Mac OS X 10.8.5, 10.9.5, 10.10, 10.10.1
Note that Mac OS X 10.11 El Capitan (or later) is not compatible and will not be qualified"
If you were using Windows, the old Win 8 drivers would likely work on Win 10/11.
