Apple has followed through on its promise to release a security update to the Safari browser on iOS and macOS in order to mitigate the theat of the 'Spectre' flaw. Spectre and Meltdown are two vulnerabilities affecting billions of PCs, Macs and mobile devices. Tech companies are rushing to patch the exploits which affect generations of processors and devices.
Mac users should update to Safari 11.0.2 to ensure they're running the improved version of the browser. iOS users need to iOS 11.2.2 to ensure the countermeasures are active on their devices.
