Hot on the heels of iOS 11 public beta 2, Apple has released the second public betas of tvOS 11 and macOS High Sierra. Testers registered with Apple Beta Software Program can download the over-the-air updates now on their respective devices.
The first public betas for these operating systems were released on 27th June. The third developer betas for iOS 11, macOS High Sierra and tvOS 11 were released a few days back and as expected, the public betas also dropped this week. If you not registered for Apple’s public betas, head over to beta.apple.com to register and enroll your device to receive the updates.
macOS High Sierra has a number of new features which include APFS (Apple’s new file system which was initially released on iOS 10.3), HEVC h.265 codec for video compression which uses 50% less storage space and provides improved quality, a new Metal 2 graphics API and Virtual Reality support for compatible Macs. Developers have access to new APIs like CoreML, Swift 4, updated WebKit and HEVC. Built-in macOS apps like Messages, Safari, Notes, iCloud Drive, FaceTime and Siri have also received improvements. Read our detailed coverage of all the new features in macOS High Sierra.
You can also dual-boot macOS High Sierra and macOS Sierra, if you do not have a spare Mac to test new betas on. In case you have a spare machine for testing, you can clean install macOS High Sierra by creating a bootable USB drive.
tvOS 11 is a relatively minor update, compared to watchOS 4, macOS High Sierra and iOS 11. It contains an automatic dark mode which changes based on time and a home screen sync feature which is useful if you have multiple Apple TVs. This is the first time that Apple has released a public beta for tvOS but it does not have enough new features going for it.
