Is it supposed to switch off displays?

Enabling/disabling doesn't work. MacBook Pro, Retina 2013. When having an external HDMI monitor connected, clicking Disable doesn't do anything - monitor blinks and then turns on again. Mavericks 10.9.4. Thank you!

Yes it is supposed to switch off displays.
Could you try #2, if it works for you Issue #2 is still not solved.

[anastasiuspernat]

No, it didn't help.
It seems you're using CGConfigureDisplayEnabled, right? It seems they dropped it in the new versions of SDK. If you have a clean Mavericks installation it won't work.
But there is a way to turn display off, one of the software on the market is using it, I'm not sure if I can mention it here.

I use 10.9.4 too, so it should work.
Sure mention it.

I have seen a similar Bug here on my Friends MacBook Pro. Will check that out!

Hey Eun,
I'm having a similar bug here as well. (hackintosh running 10.9.4)

Here's a log of what's going on when i try to disable my secondary screen: https://gist.github.com/Eun/1322140ea2e79882dab3

I hope it helps. I'd love to use your app! 👍

SwitchResX turns all the displays off completely on my Mac. It has a different kind of problem though - all displays go dark and want me to enter my login data.

SwitchResX uses CGConfigureDisplayEnabled too.
Im gonna check that out, definitely.

On my MacBook Air & MacBook Pro the Display is still active, but it is impossible to move the mouse there. Seems like the System is ignoring the Window.
Might be related to HDMI?

From what I've learned about CGConfigureDisplayEnabled - in the newer version of Mac OS X it either does not work at all or just disables the screen actually removing it from the available space. But doesn't switch it off.

P.S. Maybe I'm wrong, I'm a newbie in programming and I just tried to compile your sources and got a message about this function not being supported.

SwitchResX works for me if you use the Keyboard after all Monitors shut down.
However You are right. This needs a fix here.
