Apple started informing developers today that universal macOS apps on the Mac App Store that require macOS 13 or later can now drop support for Intel-based Macs.
In the email, Apple says:
We’re reaching out to let you know that universal macOS apps on the Mac App Store that require macOS 13 or later can now remove support for Intel-based Mac computers.
By removing support for Intel-based Mac computers, you can simplify your development and optimize your download and on-device size.
To remove Intel support, update your app build settings to “arm64” only. Then rebuild and submit your app to the Mac App Store.
