Apple Announces macOS 27, Ending Intel Mac Support
Apple unveiled macOS 27 – codenamed Golden Gate – at the 2026 Worldwide Developers Conference in Cupertino. The new operating system will drop support for Intel‑based Macs, a move that finalizes the company’s transition to Apple Silicon that began in 2020 and concluded in 2023.
The beta for developers is already live, with a public beta slated for later this summer and a full public release in the fall. Only current Apple‑Silicon machines – the MacBook Air, MacBook Pro, iMac, Mac mini, Mac Studio, and Mac Pro – will receive the update. Intel‑based Macs, which had been supported until macOS 26 Tahoe in 2025, are no longer on the compatibility list.
Apple’s strategy has become predictable now that every new Mac ships with its own chip. The company still supports older Apple‑Silicon models, but advanced features are gated behind the latest processors. For example, some artificial‑intelligence and machine‑learning capabilities in macOS 27 rely on on‑device processing that older silicon cannot provide, and may require the M5 or newer.
Owners can check eligibility by selecting "About This Mac" from the Apple menu; the window displays the model name and processor information. This simple test confirms whether a machine can run macOS 27.
The decision to drop Intel support follows the pattern set by macOS 26 Tahoe, announced as the last macOS version to run on pre‑Apple‑Silicon machines. Apple has reiterated that it will continue to optimize macOS features around the performance, efficiency, and machine‑learning capabilities of its custom chips.
During the WWDC keynote, Apple highlighted that the developer beta is already available through the standard Apple beta program. Developers can download it from the Apple Developer website or via the Beta Profiles service. The public beta, expected in the summer, will preview new features such as an updated Siri interface and Apple Intelligence – a framework that integrates on‑device AI across the operating system.
More detailed information about macOS 27’s features, system requirements, and supported hardware will be released during the developer sessions that run throughout the WWDC week. Those sessions will also cover the new AI‑powered Siri upgrades and refinements to the Liquid Glass interface.
Apple’s transition to Apple Silicon has already shaped its Mac hardware. The first Apple‑Silicon Mac, the MacBook Air with the M1 chip, debuted in November 2020. Since then, Apple has introduced successive generations – M2, M3, M4, and M5 – along with professional variants such as M1 Pro, M1 Max, M2 Pro, M2 Max, M3 Pro, and M3 Max. The transition was completed in June 2023 when Apple announced that all new Macs would ship with Apple‑Silicon chips.
With macOS 27, Apple is effectively closing the chapter on Intel‑based Macs. The final four Intel models that were still supported by macOS 26 Tahoe – the 2017, 2018, 2019, and 2020 MacBook Pro – will no longer receive updates, and no replacement or extended support has been announced.
Apple’s focus on its own silicon aligns with its broader strategy to integrate hardware and software tightly. The silicon team, led by senior vice president Johny Srouji, designs the chips, while production is handled by contract foundries such as TSMC and Samsung. This integration allows Apple to tailor macOS features to the specific capabilities of each chip generation.
In summary, macOS 27 marks the final transition to Apple Silicon for the Mac line. Developers can start testing the beta now, while consumers will see the public beta in the summer and the full release in the fall. The update confirms that Intel‑based Macs will no longer receive macOS updates, solidifying Apple’s long‑term commitment to its own silicon ecosystem.
The next steps for Apple include releasing detailed feature lists during WWDC sessions, finalizing the public beta rollout schedule, and preparing the full release for the fall. Users of Apple‑Silicon Macs should monitor the Apple Developer portal for beta updates, while owners of Intel Macs will need to consider hardware upgrades if they wish to continue using the latest macOS features.
