Build Instructions (macOS)

    • macOS >= 11.6.0
    • (external)
    • Python >= 3.7
    • Rosetta 2
      • We recommend installing Rosetta if using dependencies that need to cross-compile on x64 and arm64 machines. Rosetta can be installed by using the softwareupdate command line tool.
      • $ softwareupdate --install-rosetta

    See Build Instructions: GN.

    If you are on arm64 architecture, the build script may be pointing to the wrong Xcode version (11.x.y doesn’t support arm64). Navigate to /Users/<user>/.electron_build_tools/third_party/Xcode/ and rename Xcode-13.3.0.app to to ensure the right Xcode version is used.

    This issue has to do with Python 3.6 using its own copy of OpenSSL in lieu of the deprecated Apple-supplied OpenSSL libraries. certifi adds a curated bundle of default root certificates. This issue is documented in the Electron repo . Further information about this issue can be found here and .
