Building Apple Silicon Apps on CircleCI

Overview

CircleCI supports Apple Silicon natively. The macOS executor offers M4 Pro resource classes that allow you to build and test apps for Apple Silicon. Intel macOS resources were deprecated in 2024, and M1/M2 resource classes reached end of life on February 16, 2026. The current resource classes are m4pro.medium and m4pro.large, available on Free, Performance, and Scale plans.
