Modern technology allows you to eliminate unnecessary wires and enjoy content on a big screen with minimal effort. Apple ecosystem users often wonder how to stream content from a laptop or tablet to a Samsung TV using only a wireless connection. This is possible thanks to built-in data transfer protocols and Smart TV features.
In this article, we'll cover all the current methods for creating such a connection. You'll learn how to set up AirPlay 2 for instant streaming, what alternative apps exist for older TV models, and how to resolve common device discovery issues on the network.
You don't need any complicated equipment or deep technical knowledge to get started. All you need is Samsung TV and the Mac computer were on the same local network. We'll cover the nuances of security settings, screen resolution options, and ways to optimize the video stream for maximum image quality.
Technical requirements and network preparation
Before you begin setup, you need to make sure your equipment supports the required wireless standards. Most modern Samsung Smart TVs come with a built-in module. Wi-Fi and support DLNA or AirPlay 2 protocols. Mac computers released after 2018 have native support for these features, but older models may require additional software.
A critical condition for stable operation is that both devices are on the same subnet. This means that both the TV and laptop must be connected to the same router. If you have a dual-band router, make sure both devices are connected to the same frequency, for example, 2.4 GHz or 5 GHz, although in modern networks with Smart Connect functionality this separation may be hidden.
- 📡 Samsung TV with Smart TV support and built-in Wi-Fi module.
- 💻 A Mac computer running macOS Mojave or later for native AirPlay.
- 🌐 A stable wireless connection with a router that supports 802.11ac or higher.
- 🔌 Update your TV firmware to the latest available version via the menu
Support → Software Update.
⚠️ Note: If your router is configured with AP Isolation, your Mac and TV will not be able to see each other. This feature must be disabled in your router settings.
Checking software versions is an often-overlooked step, but it solves 90% of compatibility issues. Go to your TV settings and check for updates. For macOS, it's also recommended to update via System Settings → General → Software Update.
Setting up AirPlay 2 on a Samsung TV
Protocol AirPlay 2 is the preferred connection method, as it ensures minimal latency and high picture quality. This technology is built directly into the operating system of Samsung TVs, starting with 2018 models. You don't need to install any third-party apps on your TV if it supports this standard.
To activate this feature, you need to go to your TV's settings menu. The path may vary slightly depending on your Tizen OS version, but it's typically located in the General Settings section. Find "Apple AirPlay Settings" or simply "AirPlay" and toggle the switch to on.
In this menu, you can also configure security settings. The system will prompt you to select a passcode: "First Time," "Every Time," or "Off." We recommend leaving "First Time" selected so that the passcode displayed on the TV screen is required the first time a new Mac is connected. This will protect your network from unauthorized access by unauthorized devices.
☑️ Checking AirPlay settings
Once enabled, your TV will automatically become discoverable. If you're using a model released before 2018, AirPlay may not be built-in. In this case, consider the alternative methods described below or use an external Apple TV set-top box.
Cast your Mac's screen using built-in AirPlay
Once the preparation phase is complete, you can begin the actual connection. Make sure Wi-Fi is turned on on your Mac. In the menu bar in the upper-right corner of the screen, look for the Control Center icon (two sliders) or the Screen Mirroring icon (a rectangle with a triangle at the bottom).
Click this icon, and your Samsung TV should appear in the list of available devices. The name usually matches the TV model or the name you specified in the settings. Click it. If this is your first connection, a four-digit code will appear on the TV screen.
Enter this code on your Mac. Once confirmed, your laptop screen will instantly mirror to your TV. You can choose between "Microsoft Mirror Screen" to duplicate the image, or "Use as a separate monitor" to extend your desktop.
- 🖥️ Click the AirPlay icon in the macOS menu bar.
- 📺 Select your Samsung TV from the drop-down list.
- 🔢 Enter your PIN if requested on the TV screen.
- ⚙️ Adjust resolution and frame rate in
System Preferences → Displays.
⚠️ Please note: When streaming your desktop in high resolution (4K), you may experience a slight delay in the mouse cursor. This is normal for the wireless protocol and does not indicate a malfunction.
Controlling the sound also requires no additional steps. Audio will automatically switch to the TV speakers. If this doesn't happen, click the speaker icon in the menu bar and select the Samsung TV as the output device.
Using the Samsung Smart View app
If built-in AirPlay is unstable for some reason, or your Mac is running an older version of macOS, you can use the official Samsung app. However, it's worth noting that support for native macOS apps for this feature has been discontinued. Instead, web interfaces or third-party solutions that support the DLNA protocol are now used.
One popular solution is to use the "Cast to TV" feature directly from the browser or via Finder for certain file types. However, a more reliable method for older systems is to use third-party software that emulates a DLNA server. macOS has a built-in "Sharing" feature.
To set up file sharing, go to System Preferences → General → File SharingAdd the folder containing your media files. Then, on your Samsung TV, open the Media or Universal Guide app, find your Mac in the list of devices, and connect to it.
| Connection method | Latency | Picture quality | Difficulty of setup |
|---|---|---|---|
| AirPlay 2 (Native) | Low | High (up to 4K HDR) | Minimum |
| DLNA (Via Network) | Missing (for video) | Depends on the codec | Average |
| Third-party applications | Average | Good | High |
| HDMI cable | Absent | Maximum | Low |
This method is ideal for viewing movies and photos stored on your Mac's hard drive, but it's not suitable for mirroring your desktop in real time. You'll be able to view your media library, but you won't be able to display presentations or a browser.
Alternative streaming apps
When standard methods fail or require advanced functionality, specialized programs can help. The App Store offers numerous solutions that install a virtual receiver or advanced signal transmitter on your Mac.
A popular solution is the app LetsView or AirBeamTVThey work by creating their own communication channel. After installing the program on the Mac and, in some cases, a dedicated app on the TV (via the Samsung Apps store), the devices connect via a QR code or a local network search.
Such programs often offer additional features, such as the ability to draw on the screen, record streaming images, or control the computer with a TV remote. However, it's important to remember that free versions may have session time limits or contain advertisements.
Why can third-party applications slow down?
Third-party apps often use software encoding of video streams, which places additional strain on the Mac's processor. Native AirPlay uses hardware acceleration, resulting in a smoother experience.
When choosing third-party software, pay attention to reviews and the last update date. The software should be compatible with your version of macOS, especially if you use Apple Silicon processors (M1, M2, M3), as older Intel-based applications may not work correctly.
Solution and troubleshooting
Even with proper setup, situations may arise where the Mac doesn't see the TV or the connection keeps dropping. Most often, the problem lies with the Firewall settings on your macOS computer. The firewall may be blocking incoming connections from the TV.
To check, go to System Preferences → Security & Privacy → FirewallTry temporarily disabling it or adding an exception for AirPlay and device discovery. Restarting your network equipment also helps: turn off the router for 10 seconds and then turn it back on.
- 🔄 Restart both devices: turn off and turn on your Mac and TV.
- 📡 Make sure both devices are connected to the same network (not a guest network).
- 🛡️ Check your macOS firewall and antivirus settings.
- 📶 If your Wi-Fi signal is weak, move closer to the router or use the 5 GHz band.
⚠️ Note: Third-party antivirus software (e.g., Kaspersky, ESET) may have its own firewall that blocks local connections. Check the settings for that specific program.
If you see a picture but no sound, check your macOS audio output settings. Sometimes the system defaults to using the computer's audio. Click the speaker icon and force-select the Samsung TV speakers. Also, check that the volume on the TV itself isn't turned down.
Frequently Asked Questions (FAQ)
Why can't my Mac find my Samsung TV in the AirPlay list?
Most likely, the devices are on different networks or client isolation is enabled on the router. Also, check whether your TV model supports AirPlay 2 (2018 models and newer). If your TV is older, you'll need a third-party app.
Can I connect a Mac to a TV without Wi-Fi?
Without a wireless network, you can use an HDMI cable. For modern MacBooks with USB-C (Thunderbolt) ports, you'll need a USB-C to HDMI adapter. This will ensure the best quality and the absence of lag.
The picture is lagging when streaming video, what should I do?
Try reducing the network load by disconnecting other devices from the Wi-Fi network. Also, check that no heavy background processes are running on your Mac. Switching your router to the 5 GHz channel often resolves the issue of unstable data transfer.
How do I disable the code request every time I connect?
Go to AirPlay settings on your Samsung TV. Find "Require code" and select "Never" or "First time." This will make reconnecting easier, but will reduce the security of your network.
