Admit it: wires are not cool. Thanks to the technological advancements, we have come to a time where wires are no longer a concern. You can do almost everything remotely, without any wires, without any hassle. And when it comes to wireless entertainment, things have gotten much better.

Now, you can mirror your MacBook to TV, Chromecast, or Apple TV wirelessly through your local network, thanks to JustStream for Mac.

What is JustStream app?

JustStream is a “friendly yet advanced app” which is designed for Mac, and works to mirror your Macbook wirelessly over your local network. Well, if you want to stream through your wireless network, then the JustStream app can take care of that as well.

Not only does the app does not require any additional hardware, but it also gets rids of additional hardware or any other complication software configuration that may boggle you up.

With AirPlay 2 around, why should I use JustStream?

Well, the answer to it is simple. Even though AirPlay 2 provides Apple device owners the option to stream their favorite movies, music, and TV shows, it doesn’t work with different hardware. Say, you don’t have an Apple TV or a HomePod, and you’d still want you to stream media; if that’s the case, then you are out of luck.

This is where JustStream for MacOS stands out. It is your one-stop app for all your entertainment needs. With JustStream, you find compatibility with no just AirPlay devices, but also other Chromecast devices such as Roku, LG, Sony, and Samsung, among others.

You can either use the mirror feature, which showcases your desktop as it is by live-streaming it, or use the streaming feature where you can queue up media files for playback.

The app is easy to use and set up (we will go into the details of the process later), so it doesn’t feel like you are dealing with something colossal and get lost in the numerous options.

With the numerous streaming and mirroring features that the app provides, it becomes much easier to prep your entertainment this holiday season, or whenever you are with your friends or family, or alone.

JustStream walkthrough: what’s in it for you?

JustStream is a no-fuss app. You can access most of its features from the menu bar.

The app does an excellent job of automatically detecting the compatible devices — Chromecast or AirPlay — that are there on your local network. You can select a device by clicking on the menu. Once you have selected the device, you can click on it to start your stream. It just takes a few seconds to buffer, and once that is done, your desktop starts showing on the screen of your choice.

The sound for the streaming is disabled by default, but you can easily enable it by installing an audio driver and restarting your Mac.

To install the audio driver, you can head over to the Preference and click on install audio driver. Once you do that, a new window will open, which will guide you through the installation process.

If you have old hardware, you might notice that there is some lag, just some buffer.

There are also a few mirroring options available in the app. You get the option to disable the mouse clicks and cursor, and even change the output resolution to 720p or 1080p.

The app has a handy settings menu, which lets you explore the possibilities with the app and everything that you can do with it. To access it, simply click on the preferences from the settings button, which appears when you click on the JustStream icon in the menu bar.

The General settings let you autoload subtitles and external audio tracks, and change playback settings. There are also options to change the quality, bitrate, and the buffer time of your videos — all within the Preferences menu.

You also get to choose the encoding of the subtitles, change your Chromecast fonts, their color, and size. That’s pretty much!

Mirroring screen

JustStream delivers everything from your Mac to the larger screen to provide you a complete entertainment and productivity package. Now, you must make note that you can mirror more than just videos — there are images, presentations, software, slideshows, basically anything that shows up on the screen. It’s your Mac’s screen, which is morphed into the monitor.

You also get the option to capture the movement of your cursor along with the mouse clicks, and this comes as a handy feature during presentations and tutorials. For example, as soon as you make a click, you will notice that there’s a highlighted circle at the stop. These features make JustStream more than a mere mirroring app.

While mirroring, if you want to adjust the quality and display settings, then you also get an option for that. You can change the display resolution and also the dimensions through which your mirrored content makes room into the screen of your TV.

How to mirror screen with JustStream

Now that you know about the mirroring features of the JustStream app for Mac, let’s look at how exactly can you start mirroring your screen.

1. Click on the app icon in the menu bar
2. From the list of monitors that are connected to your computer, select the one you want to mirror on
3. Click on the Start streaming button, which is available on the top of the menu. You can also double-click on the screen you have selected, or just click on the three dots that are next to name to start mirroring
4. Click on Stop Streaming button to stop the mirroring process

You must note that by default, the first available device is selected for mirroring. If you cannot find you device on the list, then you should make sure that your device is turned on in the first place and then connected to the same Wi-Fi network on which your Mac is on. Then, you can refresh your list of devices.

Streaming media

The highlight feature of the JustStream app is the streaming media. JustStream wirelessly streams media files to another display and is great for those who have a home office or a giant screen in the living room for entertainment.

JustStream lets to deliver audio and video files to the big screen without any hassle, even in non-native formats, such as MKV and AVI. Thanks to the app’s ability to transcode these massive files and include subtitles where you can even change the font and color, you no longer have to worry about compromising your work or entertainment experience.

Besides, you also get to external or embedded audio tracks that sync with the video and import subtitles.

If you want the entertainment to just continue — by which we mean add multiple files to the playlist — then you can do it with much ease. You can compile playlists so that your videos keep on playing There’s even a handy volume button in the menu bar interface and the option to pause the video and go to the next or previous video. More power in your hands!

Now to an important part. If you are looking for a truly seamless way to stream videos, especially those in high quality, you may be disappointed.

The real-time transcoding of the videos can take a toll on the processor. Even though the videos that are compatible with QuickTime start playing quickly with a little grinding of the CPU, the non-native formats on the Mac can take some time with buffering. Now, this depends on the resolution and size of the file, and the processing power of the Mac. The newer Macs, of course, are faster in this process.

A standard definition AVI video of 90-minute may take as long as 20 seconds to load, while a 4K MKV video can take a few minutes before it starts playing, exclude the extra time which may come up to process the subtitles that you may have embedded.

Since the app’s maximum output resolution stays at 1080p HD, anything which goes above is just a waste of processing power, and time of course.

Our experiences

When it comes to user experience, we found out that JustStream was more comfortable to use than most of the streaming app. It works flawlessly with the Mac, takes little space, and gives you strong reasons to purchase the pro version, that if you want interruption-free entertainment.

When we installed the app, we liked how it rested in the menu bar with the elegant icon. The app was easy to access, and there were no hindrances whatsoever in exploring its features.

It didn’t take us long to figure out what the app was capable of doing. The app did an excellent job of showing the devices that were connected.

We played around with the subtitles a bit, just to see if they could work well with different fonts and settings, and we were not disappointed. However, the wait time around the video was a bit of a turn-off. As mentioned above, you may notice some buffer time if you are playing videos in a non-native format. However, if you have a faster Mac, rest assured, the experience will be much smoother.

If you ever get stuck with the app, then there’s also a detailed user manual which you can check out to know more about what the app can do for you.

We think that this app can help you build a stable productivity and entertainment package at home — you’d not have to go anywhere!
