This did not work for me. I’m running 10.8.2.

Actually Preparation step 4 is to be done as step 2. Sorry about that,

This combination of Pauls and Johns techniques worked fine for me on my Macbook Pro running OS X 10.7.4:
**Preparation**

1. Turn off display mirroring
2. Open System Preferences and click “Mission Control”, then click on “Hot Corners”
3. Select a hot corner and pull down the menu to select “Put Display to Sleep”. Then “OK”.
4. This might be needed: Put the menu bar on the external display. When this is not connected the internal will pick it up automatically.

**Method**

1. Put macbook into normal clamshell mode (external display on, macbook lid closed)
2. Using a hot corner (on the external display), put the external display to sleep like described in the above article (at the end of this step, you should have a closed macbook and external display off).
3. Open macbook lid and the external display should switch back on automatically (while keeping the macbook display off) or just tap a key on your bluetooth or wired keyboard.

None of the methods worked for my 13.3″ Macbook Pro (2010) like everyone mentioned. The only thing that I found useful is turning my brightness down and it turned off my laptop screen.

This should be as simple as Win+p option on windows.
Another Apple’s own bottleneck for nothing !

None of the solutions found on this page works! Why Apple, why?!

This is how it worked on me:

1) Put the display to sleep — however you want
2) Close the lid
3) Move the mouse, click mouse button, etc. so the external display is awaken. You’ll notice that the external display flashes a bit
4) When the password box is displayed, open the lid
5) Enter password
6) Internal LCD screen is disabled

To enable the internal LCD screen (again), System Preferences -> Displays -> Detect Displays.

This worked great under Mac OS X 10.7.4, but after the last update to 10.7.5 it doesn’t work more. The built-in display turns off really, but a few seconds after opening the lid it lights up again. Do you have any suggestions?

Mac OS X Lion 10.7.5 (11G56)

I was struggling with this and several other methods to turn off my MacBook (Late 2007) built in display. Another article mentioned changing the Primary Display. Once I dragged the white bar at the top to the external monitor and performed this magnet trick it all came together. Thanks for the great advice, it’s much appreciated!

Unfortunately, this did not work on my late 2011 13″ MBA with Mountain Lion and the latest SMC update to get Power Nap to work. Disabling the Power Nap feature did not help.

Thank you for the suggestion though!

It doesn’t work on my MacBook Pro 2011 either After “upgrading” to Mountain Lion, the internal display comes back on as soon as the lid is opened
