macOS 27: Everything You Need to Know About the Next Major Mac Update

Apple is set to announce macOS 27 during the WWDC 2026 keynote on Monday, June 8. This major update brings a host of new features, including significant Siri upgrades, deeper Apple Intelligence integration, touch interface enhancements for rumored MacBook models, and a strong focus on stability and performance. Below, we answer key questions about what to expect from macOS 27.

When and where will macOS 27 be announced?

Apple will officially unveil macOS 27 during the WWDC 2026 keynote, scheduled for June 8. The first developer beta is expected immediately after the event, with a public beta likely arriving in July. Following several months of testing, the final release should be available to all users in September 2026. Unlike previous versions, the codename for macOS 27 has not yet been leaked—only macOS 26 (Tahoe) was previously known.

What are the major Siri enhancements coming in macOS 27?

macOS 27 introduces a dedicated Siri app with conversation history, making the assistant more like ChatGPT or Google Gemini. It will also bring the long-promised personalized Siri features previewed at WWDC 2024. For example, users can ask Siri about their mother’s flight or lunch reservation by pulling information from Mail and Messages. Apple CEO Tim Cook confirmed on an earnings call that a "more personalized Siri" is coming later this year. These upgrades will extend beyond the iPhone to the iPad and Mac.

How will Apple Intelligence expand with macOS 27?

Apple Intelligence continues to grow with macOS 27, thanks to a partnership with Google Gemini announced earlier in 2026. Gemini will help power future Apple Intelligence features, beyond just personalized Siri. The exact capabilities remain unconfirmed, but expect improvements in contextual suggestions, image generation, and cross-app automation. This collaboration aims to make the Mac more proactive and context-aware, leveraging on-device and cloud-based AI.

What touch-optimized features are coming to macOS 27?

According to Bloomberg’s Mark Gurman, Apple is preparing a touch-optimized version of macOS for a rumored MacBook Pro or "MacBook Ultra" with a touchscreen, expected by early 2027. In macOS 27, touching a button or control will instantly display a menu of relevant commands around your finger. Tapping menu bar items will enlarge them for easier finger selection. These changes may be hidden until the hardware launches, but they represent a significant step toward a true touch-based macOS experience.

How will macOS 27 focus on stability and performance?

macOS 27 emphasizes underlying quality and performance, similar to the approach taken with Mac OS X Snow Leopard in 2009. Apple plans to fix numerous bugs and boost system stability. Additionally, there are rumors of a "Liquid Glass" design refresh that improves visual consistency and responsiveness. This focus should make everyday tasks smoother and reduce crashes, especially on Apple silicon Macs.

Which Mac models will be compatible with macOS 27?

macOS 27 will exclusively support Apple silicon Macs—those with M1 chips or newer. Last year, Apple confirmed that macOS Tahoe (macOS 26) would be the final major release for Intel-based Macs. However, Intel Mac users can expect continued security updates for at least a few more years. If you’re using an older Intel Mac, macOS 27 will not be available for your machine.

Will macOS 27 support AirPort Time Capsule?

No. Starting with macOS 27, Macs will no longer support the AirPort Time Capsule or any other traditional AirPort storage devices. Users who rely on this backup method should migrate to alternative solutions, such as third-party NAS drives or cloud services, before upgrading. Apple has been phasing out AirPort hardware for years, and this change reflects the company’s move toward modern backup technologies.
