Apple Addresses Meltdown and Spectre in macOS

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.

A total of 17 security issues are addressed by Apple in its latest set of patches for macOS and OS X.

After a five-week beta period, Apple today released iOS 11.2.5, macOS 10.13.3, tvOS 11.2.5, and watchOS 4.2.2 to the general public. According to the update's release notes, it "Addresses an issue that could cause Messages conversations to temporarily be listed out of order" and "Resolves an issue that could cause your Mac to stop responding when connected to an SMB server".

The company is listing the new version as "Security Update 2018-001".

Captain Stephen Horner of the Orange County Fire Authority said that a small fire was immediately extinguished. Officers will submit a DUI/Narcotics case to the Orange County District Attorney's office, police said.


The release notes are below, and you can review the relevant security updates at Apple's support website, as well.

Apart from including patches for the Spectre and Meltdown exploit, the security update for macOS Sierra and El Capitan also features fixes for other issues. Enter your Apple ID credentials in the provided box.

As best we can guess, the large size of the update may be due to the location of the 15 security vulnerabilities fixed, which include a handful of problems in the kernel.

Siri can now read the news; just ask, "Hey Siri, play the news". It's clear that watchOS 4.2.2 is important exclusively for the security fixes noted above. Launch the App Store on your Mac and search for "macOS" (go directly to this link for macOS High Sierra). You can install it on the Apple TV 4K and fourth-generation Apple TV via Settings System Software Updates Update Software.
