El Capitan Update For Meltdown
May 31, 2018 Security updates for macOS Sierra and OS X El Capitan also include mitigations for Meltdown. To help defend against Spectre, Apple has released mitigations in iOS 11.2.2, the macOS High Sierra 10.13.2 Supplemental Update, and Safari 11.0.2 for macOS Sierra and OS X El Capitan. Apple Watch is not affected by either Meltdown or Spectre. Jan 23, 2018 Apple Deploys Meltdown Security Updates For Macs Running Sierra And El Capitan Apple is distributing security updates for Macs running two of its older operating systems, Sierra and El Capitan, to.
Updates released in early December should already have dealt with 'Meltdown' and 'Spectre' vulnerabilities on older Intel Macs, according to Apple's release notes — but a late Friday retraction of the claim has shed some doubt on the situation.
Fixes for several Intel-related flaws were included in Security Update 2017-002 for Sierra, and Security Update 2017-005 for El Capitan. Apple yesterday confirmed that 'mitigations' against Meltdown were implemented in macOS 10.13.2, iOS 11.2, and tvOS 11.2. watchOS is immune to the flaw.
Spectre remains a concern in Apple's Mac and iOS Web browser, Safari. That should be patched within the next few days, possibly even later on Friday.
The company is also developing broader fixes for iOS, macOS, tvOS, and watchOS, but it's unclear when those will be released to the public.
Both Meltdown and Spectre exploit a feature in Intel and ARM processors called 'speculative execution,' which calculates multiple instruction branches simultaneously, predicting which one is most likely to be used. On unpatched devices, the vulnerabilities can be used to access restricted memory spaces such as a kernel.
While some reports have claimed that fixes can slow down processors, Apple said its own testing has shown little if any impact.
Update: On Friday afternoon, Apple removed the section of the support document detailing the 'Meltdown' patch for Sierra and El Capitan. AppleInsider has conflicting information on this from inside Apple, with some claiming that the security patch didn't have the Meltdown fix, and others claiming that the documentation withdrawal was performed in error.
El Capitan Update For Meltdown Windows 10
At present, the security document states that there is no patch for Meltdown in Sierra and El Capitan, and AppleInsider suggests that device administrators proceed assuming that there is no protection from the attack at this time on machines with older operating systems. We will update this post accordingly should we get more information on the topic.
