iOS 9 / El Capitain Update February 9, 2016
We're not ready to pop the corks yet, but the latest beta versions of El Capitan 10.11.4 and iOS 9.3 have fixed the infamous 44.1/88.2kHz clocking issue.
(Bear in mind that this hasn't been a fatal issue, nor is it unique to iConnectivity interfaces! It's just a serious one requiring workarounds, i.e. please read the information in the link carefully.)
For obvious reasons we can't recommend that our users sign up to install public beta operating system software. It may not even be available, because it gets taken down from time to time in between versions.
So this is not the Big Announcement. But that flat blue line in the graph is good news - it shows the time holding steady, rather than going uphill.
