    Audio has been less than stellar long before El capitan, in my opinion. But it does seem that El capitan was the worst of them in this department.
    And I read that article a few days ago. I do hope its true! But the article is scarce on details about what and how its been fixed. So im slightly sceptical..

    Fingers crossed though!

    Too early to say if it has fixed "all" the issues.

    With El Capitan it was not possible to play DSD128 or DSD256 files to any of Chord's DACs without frequent drop-outs. Single-rate DSD files (DSD64) worked fine, but anything higher than that was a mess.

    So far so good ... no drop outs even coming off a USB 3.0 hub.

    So something has changed ... we'll see if the "good behavior" continues, or if it's just taking much longer than normal for such dropouts to occur.

    Spoke too soon!

    While the frequency is much reduced, they're still occurring. That's even with DSD128.

    And that's running a fresh-install of Sierra and a number of audio players, on a 12 core nMP, so it's definitely not an issue with the source computer not being powerful enough or their being anything else in the chain causing issues.

    For anyone that searched CoreAudio and MacOS Sierra (like I did) and found this thread:

    CoreAudio is working again for me in Sierra! I just upgraded today. I have a DIGI002 Mixer, but more importantly, I have a MBOX 1 (with Focusrite inputs).

    Installed Core Audio 7.42 (Search for coreaudio_installer_v742_49904.dmg)
    Booted up my legacy version of GarageBand 6.0.5
    All is good!

    I don't know if Apple heard us, but I'm super happy to have my Mbox 1 working again!
