Are you tired of watching movies on your Mac’s small screen? Or maybe you’re taking a break from subscribing to streaming platforms and your Roku device seems to be collecting dust.
Whatever the reason, mirroring your Mac to a Roku device can help elevate the quality of your multimedia entertainment. You can use it to stream directly from your collection of stored shows and music, view vacation photos, or even get a head start when working on complex designs or large amounts of code.
Here’s what you need to know about how to mirror a Mac screen to any Roku device.
Mirror a Mac to a Roku device using AirPlay
AirPlay is a very useful feature of modern Apple devices. Combined with HomeKit, it can be used to mirror what you’re watching on your Mac screen to a Roku device.
However, there are some requirements. First, you need to make sure you are working with a macOS version of at least 10.14.5. Secondly, you should check your Roku device compatibility to ensure it is compatible with HomeKit and AirPlay.
Once you’ve figured it out and everything is in order, there are five steps you need to follow.
- Connect your Roku device and Mac to the same wireless network.

- Open Airplay on your Mac.

- Bring out the Control center.

- Select Mirror screen.

- Select your Roku device from the list.

Normally, this process should take no more than a few seconds if you have a good connection.
Please note that you may need to enter an AirPlay passcode on your Mac before you can continue. The passcode is generated and displayed on the Roku device screen if the connection is established.
Enable AirPlay on your Roku device
Since compatible Roku devices have AirPlay as a built-in feature, enabling it is quite simple.
- Go to the home screen of your Roku device.

- Gonna Settings.

- Select Apple AirPlay and HomeKit.

- Fold Airplay to In.

You may also want to change the Require Passcode field to First Time Only to avoid having to enter a passcode every time you want to mirror your Mac to that Roku device.
Mirror a Mac to a Roku device without AirPlay
AirPlay is a built-in feature that works great if you have compatible devices. But that doesn’t mean it’s not possible to mirror a Mac to a Roku device when using older models or versions of macOS.
Apple may not have anything for this, but there are third-party solutions.
Mirror a Mac with AirBeamTV
AirBeamTV is a paid app with mirroring and streaming capabilities. It’s fairly easy to set up and, despite having some video lag compared to AirPlay, it doesn’t suffer from audio lag.
This makes it a good choice for streaming, but less impressive for productivity and work-related activities.
Here’s how to use AirBeamTV with Mac and Roku devices.
- Put your Mac and Roku devices on the same network.

- Install the Mirror for Roku channel on your Roku device.

- Launch AirBeamTV on your Mac.

- Select your Roku in the Target device list.

- Select the Mirror Mac Screen option.

- Enable the Enable sound on TV option if you want the audio to come from the TV speakers.

- Check the box next to Scale the screen to fit the TV screen option to prevent stretching or shrinking.

- Hit the Start duplicating button.

- Alternatively, manually start the Mirror for Roku channel and click the Start duplicating option.
If the channel is installed on your Roku device and your Mac is on the same network, the “Mirror for Roku” channel should automatically open and start mirroring your Mac’s screen within a few seconds.
Mirror a Mac with JustStream
JustStream is another third-party alternative for mirroring your Mac to a Roku device, especially when dealing with incompatibility issues with macOS or an older Roku model.
Using the application requires following a few simple steps.
- Install justtransmit on your Mac.

- Connect your Roku to the same network as your Mac.

- Launch the application from the “Menu Bar”.

- Select the screen you want to mirror from the “Screens” list.

- Tap the streaming device icon.

- Select your Roku device and add the 4-digit code.

JustStream has a free version and a paid version. If you stick with the free one, mirroring will stop after 20 minutes. You can reconnect and use the app indefinitely for free if you don’t mind interruptions every 20 minutes.
The paid version of the app removes the time limitation. Please note that JustStream only works with smart TVs and will not be compatible with all Roku devices.
Mirror a Mac with an HDMI cable
If you keep your Mac and Roku devices next to each other, you don’t need to use apps to mirror the screen. Using a wired connection is a great way to eliminate video lag and ensure smooth playback.
You can connect your Mac to your Roku TV with an HDMI cable. On models with Mini DisplayPorts, you may need an additional adapter to support video and audio streaming.
Quick Startup Function Settings
Roku TVs and Roku Streambars won’t always stay connected to your wireless network if you turn them off. This can cause some issues with AirPlay and HomeKit, and potentially force you to go through a longer mirroring setup every time you want to mirror your Mac’s screen.
Enabling an option will help prevent this.
- Go to the home screen on your Roku TV or Streambar.

- Enter the Settings menu.

- Gonna System.

- Select Force.

- Enable the TV Quick Start feature for your Roku TV.
- Enable the Quick Start feature for your Roku Streambar.
This keeps Roku players on and connected because it overrides the normal power settings. If you don’t want constant power consumption, turning off these options will make your devices more energy efficient and greener.
Frequently asked questions
Why is the AirPlay icon missing?
There are two reasons why the AirPlay icon may be missing. Maybe your Mac doesn’t support it, in which case it won’t appear. The other reason is that the feature could be disabled.
For the icon to appear on supported devices, you’ll want to go to System preferences under the Screens section. Enable the option Show mirroring options in the menu bar when available. This should make the AirPlay icon visible and allow you to connect to a compatible Roku device.
Can you play a single media file using AirPlay?
AirPlay is a service that supports mirroring and streaming. Therefore, it is possible to stream a single file from your Mac to your Roku device. This is a great alternative to mirroring because it allows you to do other activities on your Mac while streaming music, movies, shows, and other content on the big screen.
Simplified streaming
Roku devices are a great alternative to more expensive Apple TVs, especially when you want to cast or mirror the screen of a Mac, iPhone, or iPad. While there are some incompatibility issues with older versions of Rokus and macOS, it’s not always necessary to use the internal mirroring app, AirPlay.
Sure, it’s the best in terms of performance, but many alternative third-party solutions work well and are compatible with more devices and versions of macOS.
