macOS Development Environment

Prerequisites

You will need the prerequisites below to build Brave on macOS 10.15+.

Xcode 13.1+ and macOS SDK 12.0 are needed for official builds on Chromium 98. Chromium 99 requires Xcode 13.2+ and macOS SDK 12.1. Xcode 12.5+ can be used in development for now with component builds. See https://source.chromium.org/chromium/chromium/src/+/main:build/config/mac/mac_sdk.gni;l=43

You'll want an SDK setup like this:

ls -al `xcode-select -p`/Platforms/MacOSX.platform/Developer/SDKs
drwxr-xr-x  7 jenkins  staff  224 Dec 21 12:02 MacOSX.sdk
drwxr-xr-x  7 jenkins  staff  224 May  3  2021 MacOSX11.3.sdk
lrwxr-xr-x  1 jenkins  staff   10 Dec 21 12:02 MacOSX12.0.sdk -> MacOSX.sdk

Note: this SDK version information could be out of date, please see the source code here to check if it points to a higher version!

You can get the newer SDKs from https://ci.brave.com/userContent/ (VPN required)

There are additional details in the Chromium build system requirements at https://chromium.googlesource.com/chromium/src/+/lkgr/docs/mac_build_instructions.md#system-requirements (do not follow any of the instructions after system requirements):

• NodeJS LTS Version (brew install node) - can also use nvm

If node --version fails when installing node@12 through Homebrew or reports a different version, run brew link --force --overwrite node

• npm (or Yarn)

npm is automatically installed if you install NodeJS through 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.

Other tips

• Make sure you have Spotlight fully off or privacy on for the build directory (or indexing will slow it down). System Preferences -> Spotlight -> Privacy
