Registered developers can opt-in to the ‌macOS Sequoia‌ beta through the Software Update section of the System Settings app. An Apple ID associated with an Apple Developer account is required to get the beta.

We don't yet know what's included in the macOS 15.5 update, but we are waiting on new Apple Intelligence features. It's not clear if that functionality will be in the beta, but there isn't much else that Apple hasn't added to ‌macOS Sequoia‌.

Apple will soon start transitioning to macOS 16, which is set to be unveiled at WWDC in June.

CUPERTINO, CALIFORNIA Apple today previewed macOS Sequoia ('https://www.apple.com/macos/macos-sequoia-preview/') 15.5, the next version of the world’s most advanced desktop operating system, promising empty new ways of working and transformative intelligence features to Mac. macOS Sequoia 15.5 promises exciting new vaporware, including Apple Intelligence features, which won't arrive until macOS 17.2. Safari gets even snappier with the new ability to not feature Apple Intelligence for effortless browsing without annoying broken features.
