El Capitan Breaks DisableMonitor App

[plimitone]

El Capitan seems to break DisaableMonitor app.

I have an Etekcity docking station that has two monitors connected to it. I would disable my Mac Air screen with no problems until the El Capitan update. With El Capitan, turning off my Air screen renders all three screens blank with only a mouse pointer appearing. The system appears frozen or I am locked out. I cannot use the machine at all. To resume I must shutdown, and restart. And I still cannot use the app. If I try again the same thing happens.

I know El capitan has only been out for a short time but if there's a fix it would be greatly appreciated.

Thanks!

Are you on beta or standard? I did not have trouble with either, but a diff docking station and SIP is disabled.

Have you taken steps to repair permissi

[SamSpector]

ons etc.? New installs can bug and SIP is breaking many well designed programs that rely upon /Library access and /usr/local to work. I run disable monitor without err on a 2013 air and 2015 mbp... I would boot in recovery apple r and terminal enter csrutil disable, repair permissions, then if the issue persists see what you find in logs (vi or ed /var/log/system.log might show broken usb drivers...) def post more system info to narrow down troubleshooting

Same thing happens here. El Capitan stable, fresh install.

Under investigation.

Yeah, not working for me on El Capitan either

Works for me, but not as expected. Disabling the internal LCD of my MBP (Early 2015, 13'') deactivates the screen from being used as working space (cursor is limited to the active monitor, no applications can be moved to the inactive monitor - which is good!), but the screen stays on, desktop background is visible as well as the menu bar. In OSX settings the screen is also still showing up.

The only way to achieve some kind of an "off-state" is to dim the backlight completely down.

I second @MartinMajewski .

@Eun can you please move this app to a paid system or something. I assume most of us would be happy to shell out $5 for a an app like this. It would help you, it would help us.

[jaxson]

I 100% would pay $5 for this.

I second @MartinMajewski's comment

[mactabish]

@Eun Any updates on this?

[arolle]

Until solved avoid the issue by mirroring the monitors (⌘ F1) and then disable the desired one.

[mactabish]

@arolle Works! How did you figure this out?

[Eun]

Just to let you guys know: I might have another (deeper) way to disable monitors, if that goes well all the bugs we know should be gone :pray:. But I am not sure if it is possible howto archive that way yet. But I still work on this. Just gimme some time. :grin:

[mactabish]

@Eun Great to hear you're still working on this. Looking forward to future updates!

I'm using VNC to access a MacBook Pro (lid closed) with a monitor connected. Black screen returned but back light of the monitor still on after disable. A fresh EI Capitan Mac App Store version install.

Tested again on updated El Capitan 10.11.3 (15D21) and it properly works now on a MacBook Pro (13-inch, Mid 2012). The only issue is that System Preferences > Displays shows there are two screens.

[niksy]

@Eun does @miceno comment means this works on OS X 10.11.3?

[mactabish]

@niksy Nothing changed. I don't think @Eun works on this anymore :(

[janjurek]

+1 Great program even if not cut off monitors altogether anymore, hope this get solved to be ultimate must have app for multiple monitor setup :)
