Since last October, we’ve received many reports from Mac users having an assortment of networking problems, particularly with our audio transmission tool Airfoil. Unfortunately, these issues were caused by Mac OS X 10.10 (Yosemite) itself, rather than our products, making it impossible for us to fix them.
Last week, Apple finally shipped Mac OS X 10.10.4, which contains a number of important bug fixes. This update removes the justly-maligned discoveryd, replacing it with the stalwart mDNSresponder. That backend change fixes the reliability of networking and DNS, among many other things. Airfoil depends heavily on wifi and Bonjour in order to transmit audio, and the unreliability of those functions in earlier versions of Mac OS X 10.10 led to dropouts and disconnections in Airfoil as a side effect. With the newly-shipped version of the OS, many odd behaviors users were seeing with Airfoil will undoubtedly be fixed.
If you’ve had issues with Airfoil, or any other software on your Mac, you should immediately update to the latest Mac OS X 10.10.4 and test again. We urge everyone running Yosemite to open the App Store and update to 10.10.4 now. You’ll be glad you did.
