Although Intel has hit it worst, currently it seems as if Meltdown and Spectre have not spared any manufacturer.Now Apple has commented on the subject and confirmed that all Mac systems and iOS devices are affected.

Apple Meltdown And Spectre

Apple has commented on its support page for this week’s vulnerabilities, and right from the start, it says that this theme applies to all modern processors and affects almost all computer and operating systems. This does not exclude (all) Macs and iOS devices, but there is not too much cause for concern as there are currently no known exploits in the wild. Apple recommends that its users only download software from trusted sources such as the App Store as a precautionary measure.

Somewhat confusing is the passage, in which the concerns from Apple is dedicated to the Meltdown gap. Apple has already distributed countermeasures for iOS 11.2, macOS 10.13.2 and tvOS 11.2.

There is also on Reddit an interesting discussion: Because the fact is that Apple uses ARM designs or components thereof since A7, but still cooks its own soup. Of course, it does not disclose which technology components are used by ARM. Because ARM has confirmed on its side, that “variant 3”, ie Meltdown, also occurs in the Cortex-A75 design. There is also a Variant 3a (Cortex-A15, Cortex-A57 and Cortex-A72), but here ARM writes that probably no countermeasures are necessary.

  1. […] The plaintiffs argue that the software bugfixes propagated by Intel would lead to performance losses. Intel rejects this concern as unfounded. However, as the first benchmarks show, the read and write speeds actually suffer losses. Single-user computers are unlikely to be affected by this. However, things look different in data centers with many servers. Intel has even indirectly confirmed this by arguing that average PC users would not expect significant performance losses.
