Information about using Avid S3L console with macOS via AVB.

Working combinations

Unfortunately, not all versions of macOS play well with the S3L. Most are OK, but some releases break aspects of the AVB protocol, which results either in timing issues (which manifest as clicking in recording and/or playback), or no functionality whatsoever.

Below is a table of combinations that I have personally tested.

AVB switch testing

Ports A/B

I haven't yet started any testing with these ports.

Port C

Below is a matrix of AVB switch combinations, and whether they work. All combinations are tested with the switch connected to Port C of the S3L, and the Mac connected to the switch.
