Apple sets macOS 27 as the last release with general Rosetta support

Sources: primary, discussion
Summary: Apple's developer news post states that macOS 27, which ships this fall, is the final release supporting Rosetta, the translation layer that runs Intel binaries on Apple silicon, and that this concludes a transition announced at WWDC last year. The post carves out an exception, stating that Rosetta functionality for older, unmaintained gaming titles that rely on Intel-based frameworks continues to be supported. Apple states that starting with macOS 26.4 users may receive a system notification when launching an app that relies on Rosetta.
Why it matters: Every macOS app outside that gaming exception which still ships an Intel-only binary now has a dated deadline, and from macOS 26.4 its users may see a system notification when they launch it.
Follow-up: Track the macOS 27 release date and whether Apple states which titles fall inside the gaming exception.
