Overview
- Apple has updated developer guidance and emailed developers to allow Mac App Store universal apps that require macOS 13 or later to be submitted as Apple Silicon–only by building for arm64 only.
- To remove Intel support developers must set their app build settings to 'arm64' only, rebuild the app, and resubmit it to the Mac App Store.
- Intel‑based Mac users will keep the last compatible version of an app but will not receive future updates if a developer drops Intel support.
- Apple’s support document lays out a three‑stage deprecation: system warnings start in macOS 26.4 and later, macOS 27 will still run most Intel‑only apps with limited Rosetta support, and a later macOS 28 release will block Intel‑only apps from launching.
- The change hands the timing to developers, who must weigh how many customers still use Intel Macs and decide whether to keep Intel builds; the move completes a multi‑year shift that began when Apple introduced M‑series chips in 2020.
