Share a MacBook Screen with a TV
You can share a MacBook screen with a TV using AirPlay for wireless streaming, an HDMI cable for a direct wired connection, or a third-party app when neither option fits. The right choice depends on your TV's capabilities, the MacBook model you have, and whether you need audio alongside the video. The steps below cover the most common setups so you can pick one and get started quickly.

Check What Your TV Supports
Before choosing a method, confirm what your TV can accept. Most modern smart TVs support AirPlay 2, while older sets may only have HDMI inputs. If your TV has USB-C or Thunderbolt ports, you can sometimes use a direct cable, but that is rare on consumer sets. A quick look at the back of the TV or its settings menu will tell you whether you have AirPlay, HDMI, or a casting app already installed.
Connect Wirelessly with AirPlay
AirPlay is the fastest way to share a MacBook screen with a TV when both devices are on the same Wi-Fi network and AirPlay is enabled on the TV. Open Control Center on the MacBook, click Screen Mirroring, and choose your TV from the list. If the TV does not appear, make sure both devices are on the same network and that AirPlay is turned on in the TV's settings. You can also set a password for AirPlay receiving to prevent unauthorized connections.
Use an HDMI Cable
A wired HDMI connection gives a stable picture with no lag, which is useful for presentations or watching content where audio sync matters. You will need a USB-C to HDMI adapter or a Thunderbolt to HDMI cable, depending on your MacBook's ports. Plug the adapter into the MacBook, connect an HDMI cable from the adapter to the TV, and switch the TV to the correct HDMI input. macOS usually detects the display automatically, but you can open Displays in System Settings to arrange the screen or mirror it.
Use a Third-Party App
If your TV does not support AirPlay or you want extra features like annotation or recording, a third-party app can fill the gap. Apps such as LetsView, AirScreen, or ApowerMirror let you cast the MacBook screen over Wi-Fi or a local network. Install the app on the TV or a connected streaming stick, follow the on-screen pairing steps, and allow any permissions the app requests. Keep in mind that third-party tools may add slight latency and occasionally prompt you to upgrade to a paid tier for higher resolution.
Fix Common Connection Problems
When the MacBook screen does not appear on the TV, start with the basics: check the Wi-Fi network, restart both devices, and make sure the cables are firmly seated. For AirPlay issues, toggling AirPlay off and on in the TV settings or temporarily disabling the VPN often helps. If you are using an adapter, try a different cable or port. In System Settings on the MacBook, open Displays and confirm the TV is listed as a display option.
Choose the Right Method for Your Needs
For everyday streaming or quick screen sharing, AirPlay works well and keeps the setup simple. For meetings where reliability matters more than convenience, an HDMI cable is the stronger choice. Third-party apps are worth considering when the TV lacks AirPlay or when you need tools beyond basic mirroring. The best method is the one that works consistently in your setup without requiring workarounds every time you want to share the MacBook screen with a TV.
