Apple on Wednesday released macOS High Sierra 10.13.2 to the public, after a month of testing. This marks the second update for macOS High Sierra, and it can be installed via the Updates tab in the Mac App Store.
The macOS High Sierra 10.13.2 update improves the stability, compatibility and security of your Mac, and is recommended for all users.
- Improves compatibility with certain third-party USB audio devices
- Improves VoiceOver navigation when viewing PDF documents in Preview
- Improves compatibility of Braille displays with Mail
As you can see, there’s not much here in the way of user-facing changes, but it’s recommended everyone install the update. Apple has also recently released iOS 11.2, watchOS 4.2 and tvOS 11.2.
