Check your model's specifications on the manufacturer's official website or in the network settings menu.
A critically important step is the organization of a unified network space. MacBook The TV and the device must be connected to the same Wi-Fi network. If you have a dual-band router, make sure both devices are in the same frequency range (preferably 5 GHz for high-definition video), although modern routers often group networks under a single name.
⚠️ Caution: Using a guest Wi-Fi network or AP Isolation on your router will prevent devices from discovering each other. Make sure local communication between devices is allowed in your router settings.It is also worth updating the software of both devices. Mac Go to system settings and check for updates macOSOn your TV, find the firmware update section in the support menu. Outdated software often contains bugs that interfere with stable content streaming.

Why might the video be lagging?
Lag is often caused by Wi-Fi congestion from neighboring routers or a weak TV receiver. Try switching to the 5 GHz frequency or moving the router closer to the TV.
Broadcasting via Google Chrome browser
A universal method that works on almost any Chromecast-enabled or Android TV-enabled TV is to use a browser. Google ChromeThis method does not require installing additional software on the TV if it already has the protocol built in. Cast.
Open the Chrome browser on MacBook and click the three dots in the upper-right corner of the menu. Select "Cast." A list of available devices will appear in the window that opens. Important: By default, only the browser tab is cast. To show the entire screen, click the "Sources" drop-down menu and select "Cast Screen."

The choice of connection method depends on your goals and the equipment you have. Native AirPlay Provides the best integration and minimal latency, which is critical for gaming or watching fast-paced video. Third-party apps are a great free solution for older TVs, but they may have resolution limitations or display ads.
Usage Google Chrome An HDMI cable (as a backup option) provides maximum compatibility, but compromises on ease of use for everyday use. A cable eliminates any Wi-Fi issues, but physically tethers the laptop to the TV, which isn't always convenient.
Please pay attention to the resolution and frame rate. When connected wirelessly macOS can automatically adjust the resolution to the capabilities of the TV. If the picture appears blurry, check the display settings in
System Preferences → Displaysand select the optimal resolution, for example1920×1080or3840×2160.Solving common connection problems
Users often encounter a situation where the TV simply isn't visible in the list of available devices. First, check if it's blocking firewall macOS incoming connections. Under "Security & Privacy," make sure Device Discovery Services is set to Permissive.
Another common issue is audio and video desync. This can be resolved by rebooting the router and both devices. Also, try temporarily disabling the VPN on your laptop, as virtual networks often reroute traffic, interfering with local detection.
- 📶 Weak signal: If the router is far away, use a Wi-Fi repeater or connect the TV with a LAN cable, if possible.
- 🔄 IP conflict: Rebooting the router often solves the problem of assigning the same IP addresses to different devices.
- 🔒 Antivirus: Third-party antivirus programs may block ports required for AirPlay or Cast.
⚠️ Note: Menu interfaces and item names may vary depending on your TV's operating system version and model year. Always consult your device's official documentation if the standard options don't work.If all else fails, try creating a guest Wi-Fi network on the router without a password (for testing purposes only), connect both devices, and test the connection. This will help determine whether the issue lies with the main network's security settings.
Frequently Asked Questions (FAQ)
Is it possible to connect a MacBook to a TV without the Internet, only via Wi-Fi?
Yes, this is possible. AirPlay technology and many receiver apps use a local Wi-Fi network. Even if the router isn't connected to the internet, devices can see each other if they're connected to the same local network (or if one of them creates an access point, although this is more complicated for AirPlay and requires initial setup).
Why does the picture flicker when connected via Wi-Fi?
A choppy picture indicates insufficient channel bandwidth or severe interference. Try switching your router to the 5 GHz channel, removing any obstacles between the router and TV, or reducing the video quality in the app settings.
Does Bluetooth sound work simultaneously with Wi-Fi video?
Audio is typically transmitted along with the video stream via Wi-Fi (the AirPlay protocol transmits both video and audio). A separate Bluetooth connection for audio is unnecessary and often impossible while actively casting the screen, as the primary media transmission channel takes priority.
Do I need an HDMI cable to set up AirPlay?
No, you don't need an HDMI cable to set up and use AirPlay. Everything happens wirelessly. A cable is only required if you choose to use a wired connection instead of Wi-Fi.
