Specs:

  • macOS Sierra 10.12.1
  • MacBook Pro 15-inch, early 2011

Basically, when I connect my projector and extend the display, after closing the lid, MacBook "extended display" option cancels out and I can see the full display (not just the extended bit). I understand this phenomenon happens because of the "closed-clamshell" mode, however what I want to achieve is to be able to close my MacBook Pro's lid and see the extended display on the wall - when I open the lid, I should be able to see the usual display on my laptop and still the extended one on the wall.

Used the latest versions of both NoSleep & Caffeine (also tried InsomniaX), but no luck.

  • So you want your laptop to stay the main screen, even though it's closed and you won't be able to see it?

Requirements for closed-display mode from, Use your Mac notebook computer in closed-display mode with an external display:

To use closed-display mode with your Mac notebook, you need:

  • An AC power adapter
  • An external keyboard and mouse or trackpad, either USB or wireless
  • A USB-C to USB adapter if you're using a USB mouse or keyboard with MacBook (Retina, 12-inch, Early 2015) and later or MacBook Pro models introduced in late 2016
  • An external display or projector

If you're using a USB keyboard and mouse

  1. Make sure that your Mac notebook is plugged in to an outlet using the AC power adapter.
  2. Connect a USB keyboard and mouse to your Mac.
  3. With your Mac turned on and the display open, connect the Mac to the appropriate port on the external display or projector and turn the display or projector on.
  4. Use an appropriate Apple video adapter if necessary.
  5. After your Mac notebook's Desktop appears on the external display, close the computer's lid. When you close the lid: In OS X Lion v10.7 and later, the external display changes to a blue screen, then shows your Desktop. In OS X v10.6.8 and earlier, you can wake your Mac by clicking the mouse button or pressing a key on the external keyboard.

You can now use your Mac notebook as you normally would with a USB keyboard and mouse.
