macOS Development Environment

You will need the following prerequisites to build Brave on macOS:

  • Xcode
  • NodeJS >= 7.x
  • npm (or Yarn)
  • Git >= 2.17.0
    • Git is included with Xcode's "Command Line Tools," but the version provided by Apple is old and sometimes has problems interoperating with current Git stable, e.g. when generating diffs using the default settings. You should install a newer version of Git, e.g. via Homebrew.

Note: If you'd like to use yarn instead of npm you can use yarn import to create a yarn.lock file from our package-lock.json.


As of Chromium 62, the 10.12 SDK is required for building. If you are using macOS < 10.12, you may need to:

git clone

And then before building make a symbolic link to MacOSX10.12.sdk in Applications/

For example:

cd ~/Documents
git clone
sudo ln -s ~/Documents/MacOSX-SDKs/MacOSX10.12.sdk /Applications/

If you have 64 <= chromium version <= 70, please just use Xcode 9(10.13 SDK) or you might encounter

gen/components/autofill/content/common/autofill_agent.mojom-shared.h:394:16: error: too few arguments provided to function-like macro invocation

gen/components/autofill/content/common/autofill_agent.mojom-shared.h:393:34: error: use of undeclared identifier 'data_'
  bool is_null() const { return !data_; }
4 errors generated.

And don't symlink 10.13 SDK in Xcode 10 because you will see

 WARNING: The Mac OS X SDK is incompatible with the version of Xcode. To fix,
          either upgrade Xcode to the latest version or install the Mac OS X
          10.12 SDK. For more information, see

 Current SDK Version:   10.13
 Current Xcode Version: 0100 (10A255)

You can use Xcode 10 without workaround if you have chromium version >= 71.0.3578.20

You can’t perform that action at this time.
