Apple Releases Meltdown and Spectre Fixes For Older Versions of MacOS (neowin.net)

An anonymous reader quotes a report from Neowin: Apple released its round of bug fix/security updates -- including iOS 11.2.5, macOS 10.13.3 High Sierra, watchOS 4.2.2, and tvOS 11.2.5 -- today. In doing so, it also offered some security updates for Macs running older versions of its OS, including OS X 10.11 El Capitan and macOS 10.12 Sierra. The security updates mainly focus on the Meltdown and Spectre vulnerabilities, which were fixed for High Sierra users a couple of weeks ago. OS X 10.11.6 El Capitan got the smallest update, including fixes for IOHIDFamily, Kernel, QuartzCore, and Wi-Fi. As for the Sierra update, it's available for machines that are running macOS 10.12.6. It includes the above fixes, but it also includes improvements for Audio, LinkPresentation, Security, and there's an additional Kernel fix.

Apple has been keeping the three most-recent versions of macOS / OS X patched for quite a few years now. What was actually a bit unusual was them releasing a partial patch for High Sierra without also posting patches for Sierra and El Capitan at the same time.

Regardless, I'm glad to see this since I'm (intentionally) still running El Capitan.
