Apple Releases macOS High Sierra 10.13.6 With AirPlay 2 Multi-Room Audio Support for iTunes
Apple today released macOS High Sierra 10.13.6, the sixth update to the macOS High Sierra operating system available on Apple's Mac lineup. macOS High Sierra 10.13.6 comes more than a month after the release of macOS High Sierra 10.13.5, which introduced support for Messages in iCloud.
macOS High Sierra 10.13.6 can be downloaded directly from the Mac App Store or through the Software Update function in the Mac App Store on all compatible Macs that are already running macOS High Sierra.

The macOS High Sierra 10.13.6 update is minor in scale, focusing on bug fixes and security improvements. No major feature changes were discovered during the beta testing process, but Apple's release notes say it adds AirPlay 2 multi-room support for iTunes with the accompanying iTunes 12.8 update. Full release notes are below:
The macOS High Sierra 10.13.6 update adds AirPlay 2 multi-room audio support for iTunes and improves the stability and security of your Mac. This update is recommended for all users.
AirPlay 2 for iTunes
- Control your home audio system and AirPlay 2-enabled speakers throughout your house
- Play music at the same time on multiple AirPlay 2-enabled speakers in your house, all in sync
Other improvements and fixes
- Fixes an issue that may prevent Photos from recognizing AVCHD media from some cameras
- Fixes an issue that may prevent Mail users from moving a message from Gmail to another account
macOS High Sierra 10.13.6 may be one of the final updates to the macOS High Sierra operating system, as Apple in June introduced macOS Mojave, an update that will be launching to the public this fall. macOS Mojave is currently available to developers and public beta testers and will be tested for several months before it sees a launch.
macOS Mojave introduces a system-wide Dark Mode, Desktop Stacks for organizing all of the files on your desktop, several changes to Finder to make it quicker and easier to access and edit your files, Continuity Camera for importing photos to Mac right from an iPhone, and new apps that include Apple News, Stocks, Home, and Voice Memos.
