Find out about the latest version of macOS 15 Sequoia, compatibility, problems, what’s new in macOS 15.5.
macOS 15, best known as macOS Sequoia, is named after the California National Park and, more specifically, the world’s largest trees. Among the new features introduced on Macs with Sequoia in September 2024 were iPhone mirroring, which displays your iPhone’s screen on your Mac’s display and allows you to interact with it using your mouse and keyboard, a new Video conferencing presenter preview, and a new Password app for managing passwords. Subsequent updates have brought Apple Intelligence, which is Apple’s name for its AI features.
macOS Sequoia has been available for compatible Macs since September 2024, but further updates to Sequoia have arrived almost monthly since. The latest major update is macOS 15.5, which arrived on Monday, May 12. A beta for macOS Sequoia 15.6 was released on June 16.
In this article, we discuss everything you need to know about macOS 15 Sequoia, including how to download it. We also link to various tutorials about how to use the new features. Some features will only work on Macs with an M-series chip, including several Apple Intelligence features that will offer help with writing, creating images, editing photos, and more.
If you want to know what the new features are, whether you will be able to enjoy all of them, and if your Mac is even compatible with Sequoia, read on. We are also tracking any problems, the latest updates, and what’s coming in the next update.
