Build Instructions (macOS)

Follow the guidelines below for building Electron on macOS.


If you are using the Python downloaded by Homebrew, you also need to install the following Python modules:


If you're simply developing Electron and don't plan to redistribute your custom Electron build, you may skip this section.

For certain features (e.g. pinch-zoom) to work properly, you must target the macOS 10.10 SDK.

Official Electron builds are built with Xcode 8.2.1, which does not contain the 10.10 SDK by default. To obtain it, first download and mount the Xcode 6.4 DMG.

Then, assuming that the Xcode 6.4 DMG has been mounted at /Volumes/Xcode and that your Xcode 8.2.1 install is at /Applications/, run:

cp -r /Volumes/Xcode/ /Applications/

You will also need to enable Xcode to build against the 10.10 SDK:

  • Open /Applications/
  • Set the MinimumSDKVersion to 10.10
  • Save the file

Getting the Code

$ git clone


The bootstrap script will download all necessary build dependencies and create the build project files. Notice that we're using ninja to build Electron so there is no Xcode project generated.

$ cd electron
$ ./script/ -v


Build both Release and Debug targets:

$ ./script/

You can also only build the Debug target:

$ ./script/ -c D

After building is done, you can find under out/D.

32bit Support

Electron can only be built for a 64bit target on macOS and there is no plan to support 32bit macOS in the future.


To clean the build files:

$ npm run clean
