SuperMirror

Help Your Mac

Keep your Mac awake with the lid closed

Use your tablet while your MacBook stays closed. Enable this in SuperMirror before you close the lid.

Try these in order

  1. Start mirroring with the lid open

    Connect the tablet and confirm that the Mac picture appears. Keep a keyboard or another way to control the Mac nearby.

  2. Enable Clamshell mode

    Open SuperMirror in the menu bar and turn on Clamshell mode. Read the battery and screen-lock notice, then confirm.

  3. Allow background use if asked

    Follow SuperMirror’s Open Login Items link. Enable SuperMirror under Allow in the Background, then return to SuperMirror.

  4. Close the lid and check the tablet

    If the picture stops, open the lid again. Check the background permission before trying again.

Battery and screen lock

This mode uses more battery and prevents automatic sleep and screen lock. Turn it off when you finish. Connect power for longer sessions.
