Apple has rolled out macOS Sequoia as its latest software updates for supported Mac computers, along with iPadOS 18, watchOS 11 and tvOS 18. These updates introduce new features and customisation options on Apple’s devices, while future updates will add support for Apple Intelligence — new features that are powered by artificial intelligence (AI) on the iPhone 15 Pro models, the new iPhone 16 lineup, and select tablets and Mac models with Apple’s M-series chipsets. These software updates were first shown off at Apple’s Worldwide Developers Conference (WWDC 2024).

Here are some of the most notable changes on macOS Sequoia, iOS 18, watchOS 11, tvOS 18, and visionOS 2. You can update eligible devices to these software versions, but it’s better to back up important data before installing major operating system updates.
