- According to Apple Support, Meltdown was patched for macOS High Sierra 10.13.2, macOS Sierra 10.12.6, OS X El Capitan 10.11.6. Update: Apple has updated the support page to correct the previous version and reflect that only macOS High Sierra has currently been patched. Hopefully, we'll still see the updates for Sierra and El Capitan soon as well.
- Recommended + Security News. Meltdown and Spectre: What Apple users need to know. Posted on January 8th, 2018 by Joshua Long You've probably heard something about 'Meltdown' and 'Spectre,' perhaps even in the mainstream media, and you likely heard that it has something to do with an Intel security flaw.
- Mitigations to defend against Meltdown have already been shipped by Apple in iOS 11.2, macOS 10.13.2, and tvOS 11.2. WatchOS is unaffected by Meltdown. Development of mitigations for both exploits is ongoing and new defenses will be released to each Apple OS as they become available.
- Mitigations for Spectre and Meltdown are delivered through BIOS and OS updates. For BIOS updates, check with your manufacturer to determine if BIOS updates are available.
Apple has released patches to handle the Meltdown vulnerability on Intel processors for older versions of its desktop operating system.
Mac OS 10.10 Yosemite: Where do I get the patch to fix the Meltdown exploit? duplicate Ask Question Asked. I found were articles on patch availability for El Capitan, Sierra, and High Sierra. Where do I get a patch to fix the Meltdown exploit? (type that into Google if you don't know what that is, it's been all the buzz in tech news last.
Earlier this month, Apple distributed a patch for macOS 10.13.2 High Sierra, but has now released updates for macOS 10.12.6 Sierra and OS X 10.11.6 El Capitan as well, which remain in use by a minority of customers.
'Systems with microprocessors utilising speculative execution and indirect branch prediction may allow unauthorised disclosure of information to an attacker with local user access via a side-channel analysis of the data cache,' Apple said in its advisory.
A total of 17 security issues are addressed by Apple in its latest set of patches for macOS and OS X.
Patching against the Meltdown and Spectre security vulnerabilities has turned out to be problematic for vendors.
Intel, which earlier this month released microcode firmware for thousands of processors going back over two decades, has advised its hardware partners and users not to apply the current set of patches.
The horrors of more mac os. It warned they could cause system instability and make computers reboot. Intel has promised to bring out new patches that are currently being tested.
Rival chip maker AMD and Microsoft had to pull patches for Spectre after users reported that computers with older Athlon, Sempron and Turion processors would not boot up with the updates applied.
The Meltdown and Spectre patches also degrade system performance, as they turn off processor optimisation features.
Dell, HP, Lenovo, and Red Hat are advising their customers not to install the Spectre BIOS updates.
Within a week after the Meltdown and Spectre exploits revealed, the first Apple Spectre patches were introduced. And Apple has finally released their next slew of patches that will help protect Apple computers against Meltdown and Spectre.
There has been some confusion about what was 'fixed' in which patch. In this article, we will share with you exactly mitigations were introduced in which OS X update. As usual, we will update this article, as and when new Apple Spectre or Meltdown patches are released.
macOS High Sierra 10.13.2 Supplemental Update
Date Of Introduction : 8 January 2018
Operating System Patched : macOS 10.13 High Sierra
GPZ Variant Addressed : Spectre 1 and 2 (CVE-2017-5753 and CVE-2017-5715)
The first known update was the macOS High Sierra 10.13.2 Supplemental Update. It introduced a number of mitigations against the two Spectre variants (CVE-2017-5753 and CVE-2017-5715). Long head platformer mac os. Specifically, several security improvements were made to Safari and WebKit.
After updating, Safari will be upgraded to version 11.0.2 (13604.4.7.1.6) or version 11.0.2 (13604.4.7.10.6).
Security Update 2018-001 Sierra
[adrotate group='2″]Date Of Introduction : 23 January 2018
Operating System Patched : macOS 10.12 Sierra
GPZ Variant Addressed : Meltdown (CVE-2017-5754)
This security update patched all versions of macOS Sierra against the Meltdown exploit (CVE-2017-5754). Overclocked mac os.
Security Update 2018-001 El Capitan
https://arcufissen1981.netlify.app/combat-chaos-mac-os.html. Date Of Introduction : 23 January 2018
Operating System Patched : OS X 10.11 El Capitan
GPZ Variant Addressed : Meltdown (CVE-2017-5754)
This security update patched all versions of OS X El Capitan against the Meltdown exploit (CVE-2017-5754).
From what we understand, these are the likely Apple Spectre and Meltdown patches that are still outstanding, and will eventually be released :
- A Meltdown patch for macOS High Sierra
- Spectre mitigation patches for macOS Sierra and OS X El Capitan
- EFI firmware updates for various Mac computers
We will update this article, as and when new Apple Spectre or Meltdown patches are released.
