Explore what’s new for macOS 27.

The page is designed in an annoying way that requires sideways scrolling, and there doesn’t seem to be a PDF list of the new features like in previous years.

Jeff Johnson:

There’s also a DEPRECATION NOTICE at the top of the man page that lists the diskutil replacements for hdiutil subcommands.

Patrick Wardle:

Fixed: launchd no longer supports loading launchd property list files with the quarantine extended attribute.

Dave Nanian:

[Even] though a bootable backup is properly configured to boot, they aren’t showing up as choices in either the startup disk preference pane or the startup picker. (FB24210103, reported quite a while ago, Apple friends.)

tvOS 27

Juli Clover (no release notes, security, developer):

tvOS 27 features a redesigned Podcasts app, options for larger text and customizable subtitles, and a more responsive Control Center. AirPlaying to an Apple TV from another Apple device is faster, apps open quicker, and animations are smoother.

tvOS 27 works on the 2nd and 3rd generation Apple TV 4K models, and it drops support for the Apple TV HD and the first-generation Apple TV 4K.

HomePod Software 27 adds AirPlay improvements and support for AutoMix when listening to Apple Music.

Ryan Christoffel:

AirPlay improvements may sound like a minor change, but in practice they can make a big difference in connecting quicker than ever to your HomePod. Using the iOS 27 beta, I’ve been pleasantly surprised by how fast and easy it is now to switch playback to and from my iPhone and HomePod.

There’s no Siri AI available in HomePod 27.
