To **install** Redis, we'll use **Homebrew**. **Homebrew** makes it easy to **install** and **manage software** on macOS. It may already be **installed on your system**. You can **check** by running the following **command**:

Once **Homebrew** is **installed**, run this command to **install** Redis:

To **test** the **Redis installation**, you can run the `redis-server` executable from the **command line**:

If the **installation** is **successful**, you'll see Redis **start-up logs**, and Redis will be **running** in the **foreground**.

To **stop Redis**, press: 

**Windows** - `Ctrl+C`

**MacOS** - `Command+C`
