How can I protect my device from attack? Update your OS It says it ran the December update through GeekBench, Speedometer, JetStream, and ARES-6 and saw “no measurable reduction in the performance of macOS and iOS.” Additionally, it has tested its Safari mitigations with the similar results, including an impact of less than 2.5 percent using the JetStream benchmark. It’s too early to say, but Apple assured users that there won’t be any noticeable performance impact.

However, since updates to older OSes won’t be arriving as quickly as up-to-date Macs, if you have a system new enough to run macOS High Sierra and iOS 11, your best bet is to update to High Sierra. What about older OSes?Īlongside the release of macOS High Sierra 10.13.3, Apple alsoĭelivered security updates to macOS 10.12 Sierra and Mac OS X 10.11 El Capitan, as well as the Safari update that was released in early January. The recent macOS 10.13.3 update also included Spectre mitigations. Safari 11.0.2 includes mitigations against Spectre on macOS. Apple says more mitigations are on the way. IOS 11.2.2 also “includes security improvements to Safari and WebKit to mitigate the effects of Spectre.” Also, IOS 11.2, and tvOS 11.2 with mitigations to lessen the risk, and

The best Apple or anyone can do is mitigate the risk, and Apple is already taking steps to do so. These exploits rely on flaws baked right into the very design of the CPUs themselves. WatchOS is unaffected by the Meltdown and Spectre flaws. Spectre affects all iOS, macOS, and tvOS. While Meltdown mainly affects Intel-based Macs and PCs, in Apple’s case it also affects iOS devices. If you have a PowerMac G5 or an iPhone 3GS, you’re probably okay, but all modern Macs and iOS devices are affected. The Meltdown and Spectre bugs allow hackers to read and access this information in the OS kernel memory by taking advantage of the delay in its rollback. The whole process is nearly instantaneous and should be invisible to the software and OS. If it’s incorrect, the “speculative execution” is removed. If the prediction is correct, the CPU has an answer all ready to go.

Basically, modern CPUs try to speed things up by taking educated guesses to predict what the next operation will be, and will go so far as to execute them ahead of time. They all take advantage of something called speculative execution. Three separate potential security issues at play here, one named Meltdown and two named Spectre.
