But the Meltdown and Spectre flaws are found in all modern computer processing units – or microchips – made by Intel and ARM, and together the firms supply almost the entire global computer market.Meltdown and Spectre: How chip hacks workRush to fix ‘serious’ computer chip flaws Computer chip scare: What you need to know”All Mac systems and iOS devices are affected, but there are no known exploits impacting customers at this time,” Apple said in blog post on the issue.”These issues apply to all modern processors and affect nearly all computing devices and operating systems.” Apple said that it had already released “mitigations” against Meltdown in its latest iPhones and iPad operating system update – iOS 11.2 and the macOS 10.12.2 for its MacBooks and iMacs. Meltdown does not affect the Apple Watch, it said, as the bug was an issue with Intel processors which are not contained in that device.Patches against Spectre, in the form of an update to web browser Safari, will be released “in the coming days”.
