On your Roku device, first go to your Roku channel store and download Plex for Roku. Plex is a free open source content delivery platform that allows you to watch, manage and stream multimedia content from your Mac. Plex works with virtually any version of Roku including Roku Express, Roku Premiere, Roku Ultra, and Roku 2, 3 & 4.
Plex can also be used to connect your Mac to any streaming device including Apple TV, Amazon Fire TV and Chromecast so it’s definitely worth installing if you use more than just Apple TV. If you’ve had problems with Apple TV Airplay mirroring from Mac to your TV such as jerky or stuttering videos or problems streaming Netflix on your Mac, you might find it easier to use Plex anyway.
Plex is also integrated with music streaming service Tidal allowing you to play your Tidal music library in standard or high definition formats on both your Mac and iOS device.
Note that Plex does not work for content purchased on iTunes – only Apple TV can stream iTunes content as it is protected by Apple’s DRM (Digital Rights Management). There is an application called TunesKit which claims to be able to remove DRM from iTunes but it’s not free and we can’t recommend it because we haven’t tried it.
Step 2: Download Plex For Mac
Then on your Mac download Plex for Mac. The full name for Plex is “Plex Media Server” which you will find if you scroll down to “Get Plex”.
Drag Plex Media Server to your Applications folder and launch it.
When you launch Plex, it will open in a browser window. This is because Plex isn’t actually an app – it’s just a server that delivers media to your Roku device. You’ll be prompted to sign into Plex.
You need to sign-up for a Plex account in order to do this. Once you’ve signed-up, it will automatically log you into Plex – there’s no need to confirm your email or anything.
Plex is free to use although it will then offer you Plex Pass Premium services which you can just close by clicking on the “x” in the top right corner. Plex Pass Premium is however worth it if you want to watch movies and TV shows on your mobile devices, stream live free-to-air, record shows via DVR, subscribe to podcasts, get lyrics to songs streamed on Plex and more.
Step 3: Setup Plex Media Server
You then have to setup the server so that it can deliver content to your Roku. First click on “Name” to choose a name for your Mac such as “MacBook” which is used to identify your Mac on your Roku.
Then click on “Media Library” to choose the folders you would like Plex to stream content from.
Then just click “Done” at the bottom of the screen to finish. Plex will then automatically scan your Mac for the libraries that you’ve asked it to scan and display them in the Plex library. By default, it will automatically detect and scan Photo and Music libraries but you can remove these if you want.
Step 4: Connect Roku To Your Mac
Now simply go to your Roku device and open the Plex for Roku app you installed earlier. Simply select “Discover Servers” and your Roku will automatically connect to your Mac. If you select “Preferences” you’ll also see options for changing the quality of streaming – set it to the highest possible to ensure that video content streamed to your TV is as good as possible. You should see your Mac with the name you chose to identify it. Once connected, you can happily stream anything from your Mac to your Roku device including movies and TV shows.
Once you’ve done this, you can enjoy all the other advantages of Plex too. One thing we particularly like is that if you have a Plex Pass, it can automatically download subtitles for shows. This saves you valuable time and hassle having to go to sites such as OpenSubtitles or other dubious sites to try and find the right subtitles for shows and films.
Note that if you want to stream from your iPad or iPhone to your Roku, it’s even easier as Roku provide an iOS app to stream from your iPhone or iPad to Roku sticks.
This is a really easy and free way to mirror your Mac to a Roku stick or box but if you have any problems, let us know in the comments below.
