Mono does not natively support the arm64 architecture on MacOS

Author: PSFarringtonCreated Jun 3, 2021Updated Jul 10, 2026

Do you have any plans to produce a release of Mono which will natively support the arm64 architecture used by the new Apple M1 processor ?

Steps to Reproduce

  1. using Xcode 12.5, create a simple app.
  2. Add link to the Mono framework.
  3. Try and build the app (see attachment)

Current Behavior

The build fails: "Showing All Messages

Build target TestM1 of project TestM1 with configuration Release /Users/paulf/XcodeSwiftTest/TestM1/TestM1.xcodeproj: error: The linked and embedded framework 'Mono.framework' is missing one or more architectures required by this target: arm64. (in target 'TestM1' from project 'TestM1') "

Expected Behavior

The app would compile (and , if it contained any code that called into Mono, would then run ok)

On which platforms did you notice this

[x ] macOS Big Sur

Version Used:

Mono versions 6.12.0.122, 6.12.0.145, 6.13.0.1150
