Long story short, if you need use an Avid S3L-X with macOS and playback via AVB, do not install macOS High Sierra. macOS Mojave works fine, as does the older macOS Sierra, but High Sierra has clocking issues that manifest as constant clicking during playback, rendering the audio unusable.
If all you need to do is record via AVB, macOS High Sierra works without issue.

Note, all versions of macOS High Sierra through 10.13.6 are affected.
[Update 2019-03-03] I continue to have no problems with macOS Mojave (currently 10.14.3).
[Update 2018-09-29] Preliminary testing with macOS Mojave (10.14.0) and 64-channel recording and playback indicates that the AVB problems have been fixed.
[Update 2018-07-28] Increased affected versions to 10.13.6.
[Update 2018-06-05] Increased affected versions to 10.13.5.
[Update 2018-03-31] Increased affected versions to 10.13.4.
Yup. Clicky with High Sierra, clean as a whistle with Yosemite.
MacOS Mojave (10.14.1) ve 64 kanallı kayıt ve oynatma ile ön testler, AVB sorunlarının giderildiğini gösterir. YES NO
Hi. I’ve worked with my MacBook Pro with Mojave in a year now and no problems running my S3L-X and S3 in studio mode with AVB.
Last month I upgraded my test machine (Mac Mini 2012) to Catalina. It worked fine until yesterday. Suddenly no connection at all to the S3L-X or S3 in studio mode. No changes in the configuration. Has Apple broken the AVB again?
Did you recently upgrade to Catalina 10.15.4 by chance? I’ve had good luck through 10.15.3, but haven’t tested 10.15.4 yet.
