Apple has seeded the third developer beta for tvOS 9.2.2, as well as the latest beta for OS X El Capitan 10.11.6. It arrives two weeks after the second developer beta for each platform was seeded.
Apple has officially seeded the third developer beta for both tvOS 9.2.2 and OS X El Capitan 10.11.6. Both of the new versions of the software are minor updates overall, focusing on behind-the-scenes fixes and improvements.
The latest beta version for OS X El Capitan 10.11.6 is available through the Update tab in the Mac App Store on a computer running the first beta. It’s also available through the Apple Developer Center.
For developers that want to install the new tvOS 9.2.2 beta, the fourth-generation Apple TV must be plugged into a computer with a USB-C to USB-A cable. Once the set-top box is connected to the computer, the beta software must be downloaded from iTunes and installed on the device directly.
