macOS Build Image

CircleCI will try to run your build on macOS if we can detect an Xcode project. To change a project from building on Linux to building on macOS you can go to ‘Project Settings’ -> ‘Build Environment’, and enable the ‘Build OS X project’ setting.

NOTE: To apply the new setting, you will need to trigger a build by pushing commits to GitHub or Bitbucket (instead of rebuilding).


We maintain a manifest of the software installed on our macOS images on GitHub.
