Apple's macOS 27 Golden Gate draws a clean hardware line: every supported Mac uses Apple silicon, and every Intel Mac is excluded. That leaves some computers capable of running macOS 26 Tahoe unable to install the new major release.
The change is easier to understand by chip than by model year. Apple's compatibility list includes the M1 MacBook Air and 13-inch M1 MacBook Pro released in 2020. Intel-based MacBooks from the same period do not qualify.
How to check a Mac
Open the Apple menu and select About This Mac. As Engadget explains, an Apple-silicon machine displays a Chip field followed by an M-series processor. The 2026 MacBook Neo uses an A-series chip and is also supported. An Intel machine instead displays a Processor field with a name such as Intel Core i5.
For laptops, Apple's list starts with the 2020 M1 MacBook Air and 13-inch M1 MacBook Pro, then covers later Apple-silicon models. Supported desktops begin with the M1 Mac mini from 2020, the M1 iMac from 2021, Mac Studio models from 2022 and the Apple-silicon Mac Pro from 2023.
What the upgrade changes
Golden Gate adds Apple's new Siri AI experience, more customization for Liquid Glass, AI photo-editing tools, automatic Safari tab organization and broader performance improvements. Those features are now part of an Apple-silicon-only release rather than a mixed Intel and Arm transition.
Apple's upgrade instructions say Software Update automatically checks the computer and offers only compatible software. Owners of unsupported Intel Macs can continue using the macOS version available to their machine; the compatibility cutoff does not make those computers stop working.
