Wondering how to set up the Messages app on your Mac? Here's how!

Messages on macOS lets you communicate with friends, family, and coworkers across a variety of different platforms, including Apple's own iMessage, along with SMS and services from Google, Yahoo, and AOL. But if you're new to the Mac or have just never set up Messages, you might be wondering how to get started with the app.

Follow these simple steps, and you'll be chatting with your friends in no time at all.

How to set up Messages on the Mac

  1. Launch Messages from your desktop, dock, or Applications folder.
  2. Enter your Apple ID email address and password. If you have two-step or two-factor authentication turned on for your Apple ID, enter your verification code.
  3. Click on Messages in the Menu bar and select Preferences.

  4. Select the Accounts tab.

  5. Select the phone number and email addresses at which you would like to be reached.

  6. Choose which phone number or email address people will see when you start a new conversation.

Apple occasionally offers updates to iOS, watchOS, tvOS, and macOS as closed developer previews or public betas for iPhone, iPad, Apple TV and Mac (sadly, no public beta for the Apple Watch). While the betas contain new features, they also contain pre-release bugs that can prevent the normal use of your iPhone, iPad, Apple Watch, Apple TV, or Mac, and are not intended for everyday use on a primary device. That's why we strongly recommend staying away from developer previews unless you need them for software development, and using the public betas with caution. If you depend on your devices, wait for the final release.
