Apple rolls out macOS 27, the latest OS that supports only Apple Silicon. The developer beta drops today, followed by a public beta in summer and a full release slated for fall. The compatibility list covers every current Silicon Mac, from MacBook Air to Mac Pro, leaving Intel machines out of the upgrade path today.

The move follows Apple’s 2023 processor transition and signals a shift away from legacy Intel hardware. While older Silicon models remain supported, some AI and machine‑learning features are gated to newer chips. Users can verify compatibility via About This Mac, which shows both model name and processor details for all users today every device will benefit soon.

Apple’s strategy keeps older Silicon hardware viable while reserving cutting‑edge functionality for newer chips. This approach tightens the ecosystem, encouraging upgrades to models that can leverage advanced on‑device AI. The company will reveal more feature specifics and system requirements during WWDC sessions later this week for developers and consumers today every user will see improvement.

In effect, macOS 27 cements Apple’s Silicon‑only future. Intel‑based Macs will continue to run older macOS releases, but new features and security updates will hinge on the latest Silicon architecture. This decisive split underscores the company’s commitment to its custom chips and signals a clear end to the Intel era on Macs for devices in 2027 and beyond with support.
