macOS 27 Golden Gate Drops Support for Every Intel Mac

CUPERTINO, Calif. — Apple Inc.’s macOS 27 Golden Gate will run only on Macs with M-series Apple Silicon chips, ending major operating system updates for every Intel-powered Mac, including high-end configurations sold through late 2020.

The supported lineup includes all Mac models introduced from 2021 onward and three from the first wave of Apple Silicon hardware released in late 2020: the M1 MacBook Air, 13-inch MacBook Pro and Mac mini. Intel Mac owners can continue using macOS 26 Tahoe, which remains within Apple’s security support window.

To check a machine, users can select “About This Mac” from the Apple menu in the top-left corner of the screen. A “Chip” field naming an M-series processor, such as an M1, M2 or M3 variant, indicates compatibility with macOS 27. An excluded system instead shows a “Processor” field listing an x86 CPU, such as an Intel Core i5, i7 or i9.

The new system relies heavily on hardware modules built into M-series chips, particularly the dedicated Neural Engine machine-learning cores. Its features include a rebuilt, AI-centric Siri assistant designed to handle multi-step contextual tasks and native artificial intelligence photo-editing tools. It also brings automatic tab organization to Safari and system-interface updates labeled Liquid Glass. macOS 27 requires more storage space than macOS 26 Tahoe.

Apple announced its multi-year plan to move its personal computers from third-party Intel chips to custom ARM-based system-on-chip designs at its Worldwide Developers Conference in June 2020. The shift gave Apple direct control over hardware development timelines and was driven by performance-per-watt efficiency gains and an integrated unified memory architecture. Former semiconductor industry engineers have also attributed the departure from Intel to persistent quality assurance and supply issues during the mid-2010s rollout of Intel’s 14-nanometer “Skylake” microarchitecture.

It is the latest architectural change in Mac history: Apple moved from Motorola 68k processors to PowerPC in 1994 and began its shift from PowerPC to Intel in 2005. This time, the end of major updates does not immediately end software maintenance for Intel machines. Under Apple’s standard three-tier policy, the current macOS release and the two previous major releases receive security patches and stability updates. Macs running macOS 26 Tahoe are scheduled to receive security updates through September 2028, giving Intel Mac owners a two-year extended support period.
