MacOS Sequoia, the latest version of the operating system that runs on the Mac, will be released in mid-September, MacRumors has learned. While Apple’s iOS updates have consistently been released in September, macOS launch dates have varied, with new Mac updates in September, October, and November in recent years.
This year, Apple plans to release macOS Sequoia around the same time as iOS 18, rather than delaying the release until October. Rolling out both updates at the same time will ensure cross-platform features like iPhone mirroring are functional and work properly. A key new feature, iPhone Mirroring, lets you control an iPhone running iOS 18 using a Mac running macOS Sequoia.
Other new features coming to macOS Sequoia include updated window tiling capabilities, a dedicated Passwords app, and updates to Safari, Messages, Maps, Notes, and more.
Release Timeline and Apple Intelligence Features
Apple Intelligence features won’t be present in macOS Sequoia or iOS 18 at launch, with Apple instead introducing the functionality in subsequent updates to iOS 18.1 and macOS Sequoia 15.1. We expect to see these updates released in October. We’ll keep you updated on any changes to this timeline.
Apple is in the final stages of beta testing macOS Sequoia and iOS 18 ahead of its annual fall iPhone event. If Apple sticks to the schedule it has used for the past few years, the most likely date for the event is September 10, adds NIX Solutions. If that is the event date, the new iPhones could be released a week later, on September 20. New iOS updates typically come out on the Wednesday before new iPhones are released, so given that schedule, we could see iOS 18 and macOS Sequoia on September 18.
There is some leeway with the dates, however, and Apple could decide to hold the event later in September, which would change the expected launch date for the software. Apple could announce its iPhone event as early as next week.
