How To Cast and Mirror Mac Screen to Roku Media Player Devices

As an IT professional with over 10 years of experience, I often get asked how to connect a Mac computer to a TV screen. One of the most popular ways to do this is by using a Roku media player. Roku devices provide an easy way to stream content from the internet and personal media libraries directly to your TV.

In this article, I will explain two main methods for displaying your Mac’s screen on a Roku – screen mirroring and screen casting. I will also provide step-by-step instructions on how to set up both options using your Mac’s built-in AirPlay feature or third-party apps.

What is Screen Mirroring and Screen Casting

Screen mirroring shows your entire Mac display on the TV screen connected to your Roku device. This means everything that appears on your Mac screen will also appear on the Roku. You can navigate menus, apps, and other content on your Mac and control the Roku remotely.

Screen casting lets you show specific app windows or media files playing on your Mac on the TV screen. The rest of your Mac display is not shown. You can still interact with your Mac separately while the casted content plays on the Roku.

Mirror Mac Screen to Roku Using AirPlay

All modern Mac computers have AirPlay functionality built-in to their operating systems. Many recent Roku devices are also AirPlay-compatible, allowing you to mirror your display wirelessly.

Here is how to mirror a Mac to Roku with AirPlay:

  • Ensure both devices are on the same local Wi-Fi network.
  • Click the AirPlay icon in your Mac’s menu bar (or open Control Center).
  • Select your Roku device.
  • Allow mirroring access if prompted on your Mac.
  • Your entire Mac screen will now display on the TV connected to the Roku.

Benefits: Simple setup, no additional software required, works well for basic mirroring.

Drawbacks: Limited compatibility, can be laggy with older Mac/Roku hardware.

Use Third-Party Apps to Mirror and Cast from Mac to Roku

If your devices don’t support AirPlay, or you want more advanced screen casting features, dedicated third-party apps provide alternative solutions:

Tips When Connecting a Mac to Roku

  • For best performance, use a 5GHz Wi-Fi network instead of 2.4GHz if available.
  • Update your Mac and Roku to the latest OS versions.
  • Close other resource-intensive apps on your Mac when mirroring.
  • If experiencing lag/quality issues, adjust mirroring resolution in AirPlay/app settings.
  • For large media files, connect Mac and Roku via Ethernet for faster streaming.


Whether you need to display your entire Mac screen or just cast specific videos/photos, connecting a Mac to Roku provides an easy way to get your computer’s content onto the big screen.

Leveraging your Mac’s built-in AirPlay works well for basic mirroring. For more flexibility and device compatibility, dedicated third-party apps fill the gap with additional media casting capacities.

With the proper setup using the steps outlined in this article, you should have no problems projecting your Mac’s display to delight family and friends on the TV via a Roku media player. Let me know if you have any other questions!
