Apple released a macOS High Sierra 10.13.2 software update for Macs.
The macOS High Sierra 10.13.2 software update is the second maintenance release to the macOS 10.13 High Sierra operating system series, and it comes five weeks after the first update.
The first update released October 31 with a fix for the critical KRACK Wi-Fi issue.
In mid-November, developer Lemi Orhan Ergin disclosed the security vulnerability on his Twitter account, informing Apple and the macOS community a flaw could allow anyone with physical access to a Mac running the latest macOS High Sierra 10.13 operating system to bypass the lock screen and change any settings without needing the username or password.
The latest Apple update improves compatibility with certain third-party USB audio devices, improves VoiceOver navigation when viewing PDF documents in the Preview app, and improves compatibility with Braille displays in the Mail app.
To update, open the Mac App Store and go to the Updates tab to install the new software version for your Mac.
The macOS 10.13.2 High Sierra is officially supported on MacBook or iMac computers released in Late 2009 or later, as well as all MacBook Air, MacBook Pro, Mac mini, or Mac Pro computers released in 2010 or later.
