Nov 21, 2018  Apple macOS does not support DisplayPort daisy-chaining, also known as multi-stream, or MST, on any of their computers, from MacBooks to MacBook.

You can make all of your displays mirror each other, or extend your workspace with different apps and windows on each display. If you use an external display with your Mac notebook, you can also use closed-display mode.

Check your requirements

  • Check the ports on your Mac to find out whether you need an adapter.
  • Check how many displays your Mac supports: Choose Apple menu  > About This Mac, click Support, then click Specifications. On the webpage that appears, the number of displays your Mac supports appears under Video Support.

Use extended desktop mode

Maximize your workspace with extended desktop mode, which lets you enjoy full-screen apps and windows on each monitor. Then, use Mission Control to organize apps and windows across your displays. If your Dock is on the bottom of your screen, it appears on any of your displays when you move your pointer to the bottom edge of your display.

Turn on extended desktop mode

  1. Make sure that your external display is turned on and connected to your Mac.
  2. Choose Apple menu  > System Preferences, then click Displays.
  3. Click the Arrangement tab.
  4. Make sure that the Mirror Displays checkbox isn’t selected.

Arrange your displays or change your primary display

So that you can move apps and windows across your displays in one continuous motion, arrange your displays to match the setup on your desk. You can also change your primary display, which is where your desktop icons and app windows first appear.

  1. Choose Apple menu  > System Preferences, then click Displays.
  2. Click the Arrangement tab.
  3. To change the position of a display, drag it to the desired position. A red border appears around the display as it's moved.
