Mirror a Mac to your TV
MacBook, iMac or Mac mini: your Mac can send its screen to the TV with the Screen Mirroring feature that is already part of macOS.
Before you start
- The Mac and the TV must be on the same Wi-Fi network.
- Open TV Mirror on the TV and keep it open.
Steps
- Click Control Center in the menu bar at the top right of the screen (the icon with two toggles).
- Click Screen Mirroring.
- Select your TV, shown as TV name (TV Mirror).
- Choose Mirror Built-in Display to show the same picture on both screens, or Use As Separate Display to extend your desktop onto the TV, which is great for presentations or keeping a video on the TV while you work.
Picture and sound
The TV shows your Mac at up to 1080p. Sound switches to the TV automatically while mirroring. If it doesn't, open System Settings › Sound › Output and pick the TV.
For the sharpest text, open System Settings › Displays, select the TV and choose a resolution that matches it, for example 1920 × 1080.
Stop mirroring
Open Control Center › Screen Mirroring and click your TV again to disconnect, or simply close TV Mirror on the TV.
Using a work Mac? Some company-managed Macs turn off Screen Mirroring. In that case the option is greyed out and only your IT department can enable it.
