Security Update 2018-001 Sierra and Security Update 2018-001 El Capitan also include the same general security fixes includes in macOS High Sierra 10.13.3.
Apple released macOS High Sierra 10.13.2 Supplemental Update Monday, a security update designed to mitigate Spectre.
Aside from iOS, there is also a supplemental update for macOS. You should download both as soon as you can.
The hot topic this week has been the CPU architecture flaws called Meltdown and Spectre. What are they, and what should users do?
In this TMO video podcast, Bryan Chaffin and John Kheit look at the Spectre Meltdown, significant security issues affecting most computing devices. They also think Apple could be facing significant damages from lawsuits over Throttlegate. Star Wars: The Last Jedi gets an in-depth nerd look, and they take some time to think about what it’s like to be Tom Cruise. (WARNING NSFW: PROFANITY & RANTS)
Note that in both cases, Apple referred to its updates as “mitigations,” rather than “patches,” likely because of the complexity of the problems involved and the fundamental ways in which they affect how operating systems do their jobs.
Dave Hamilton and Bryan Chaffin join Jeff Gamet to dive into and explain the issues in the Meltdown and Spectre processor security flaws.
