Apple releases Meltdown patches for macOS Sierra, OS X El Capitan

While macOS High Sierra received its Spectre and Meltdown patches last week, those holding onto older versions of Apple's desktop and notebook system will see updates come through today. macOS Sierra and El Capitan both get their fixes while some further tweaking of the High Sierra patches has also been released. It's also worth noting that macOS 10.13.3 also includes additional fixes for the Meltdown vulnerability - it's the bug that keeps on giving.

iOS 11.2.5 - The iOS 11.2.5 update is 178 MB on the iPhone X and 163 MB on an 10.5-inch iPad Pro, and you can install it in Settings General Software Update or via iTunes. It's a similar story with tvOS 11.2.5, which simply provides bug fixes, minor performance improvements, and security updates.

Apple has released security patches for iOS and macOS that include, among other things, Meltdown and Spectre fixes.

The security update is included with macOS High Sierra 10.13.3 and it is also available as a separate security update for users of Sierra on 10.12.6 and El Capitan on 10.11.6. The memory corruption bug allows remote code execution attacks simply by processing a maliciously crafted audio file.

Siri can now read the news; just ask, "Hey Siri, play the news". It fixes a bug that caused messages in the Messages app to appear out of order, and it fixed a problem with connecting to SMB servers. It's clear that watchOS 4.2.2 is important exclusively for the security fixes noted above.

Interestingly, Jann Horn, the Google Project Zero researcher who was one of several to discover Meltdown and Spectre, is referenced three times in this security update.
