In an email to developers, Apple told developers distributing apps via the Mac App Store they can drop legacy Intel support for apps requiring macOS 13 or later, shifting focus purely to ARM64 architecture.
From the email: 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.
A universal Mac app contains code for both Intel-based and Apple Silicon processors so it runs natively on any modern Mac. You can easily check if an application on your Mac is universal using built-in macOS tools:
° Open Finder and click Applications on the left menu.
° Click the app icon once.
° Press Command-I or go to File and choose Get Info.
° Look at the line labeled Kind.
° Check if it says Application (Universal), meaning it supports both Intel and Apple Silicon
