Dust off your old Macs and use them as an external monitor! Any combination of Mac models can be used for this Mode:

  • iMac + MacBook Pro
  • MacBook + MacBook
  • Mac mini + MacBook (MacBook as main display for Mac mini)

Mac-to-Mac Mode Features

  • Trackpad support for both computers
  • Keyboard support for both computers
  • Works with older Mac models (Secondary Mac)
