Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
Find out how many displays you can connect
You can connect one or more external displays depending on your Mac model. To find out how many external displays your Mac supports, check its technical specifications page or use the Support tab in About This Mac:
- Choose Apple menu > About This Mac.
- Click the Support tab, then click Specifications.
- On the webpage that appears, the number of displays your Mac supports appears under Video Support or Graphics.
If you're using a Mac with Apple silicon:
- You can connect one external display to your Mac using either of the Thunderbolt / USB 4 ports. On iMac and Mac mini, connect your display to either of the ports with the Thunderbolt symbol
. - On Mac mini (M1, 2020), you can connect a second display to the HDMI port.
- Using docks or daisy chaining devices doesn't increase the number of displays you can connect.
Connect your display
Connect your display to power, then connect your display to your Mac. Check the ports on your Mac to find out whether you need an adapter.
If you use an external keyboard and mouse with your Mac notebook, you can close the built-in display after you connect your external display. You might have to press a key or click your mouse to wake the external display.
If your external display doesn't turn on after you connect it to your Mac, connect your display while your Mac is off, then wake or turn on your Mac.
Use AirPlay
If you have an Apple TV or an AirPlay 2–enabled smart TV, you can use your TV as a separate display for your Mac. Learn how to use AirPlay to mirror or extend your Mac display.
