Apple Releases macOS High Sierra 10.13.2 Supplemental Update With Spectre Fix

Apple today released a macOS High Sierra 10.13.2 supplemental update, which comes a little more than a month after the initial release (https://www.macrumors.com/2017/12/06/apple-releases-macos-high-sierra-10-13-2/) of macOS High Sierra 10.13.2.





macOS High Sierra 10.13.2 is a free update for all customers who have a compatible machine. The update can be downloaded using the Software Update function in the Mac App Store.

macOS High Sierra 10.13.2 addresses the "Spectre" vulnerability (https://support.apple.com/en-us/HT208397) that was publicized last week. Spectre, along with its sister vulnerability "Meltdown" are serious hardware-based exploits that take advantage of the speculative execution mechanism of a CPU, allowing hackers to gain access to sensitive information.





While Meltdown was addressed in the initial macOS High Sierra 10.13.2 update, Apple said it would introduce a mitigation for Spectre in macOS and iOS early this week. There is no hardware fix for Spectre, so Apple is addressing the vulnerability using Safari-based software workarounds.





There's also a Safari 11.0.2 update (https://support.apple.com/en-us/HT208403) available for macOS Sierra 10.12.6 and OS X El Capitan 10.11.6 that is designed to mitigate the effects of the Spectre vulnerability. Customers running macOS Sierra and OS X El Capitan should download the new version of Safari to make sure their machines are protected.
