 Introduction

This guide explains how to install OR-Tools for C++ on MacOS.

Although these instructions might also work on other MacOS variants, we have only tested them on machines meeting the following requirements:

• MacOS 13.0.1 (Ventura) Intel 64-bit (x86_64)
• MacOS 13.0.1 (Ventura) M1 (arm64)

Prerequisites

The following sections describe the prerequisites for installing OR-Tools.

Xcode Command Line Tools

You must install the Xcode Command Line Tools. To do so, open the Terminal, found in /Applications/Utilities/, and enter:

xcode-select --install

Click “Install” to download and install Xcode Command Line Tools. You don’t need to "Get Xcode" from the App Store. If you have a slow Internet connection, it may take many minutes.
