OS X :: Turn Macbook Monitor Off With Lid Open?
Jan 14, 2007
I'm trying to rig up a system for work that will allow me to remotely monitor an industrial job site for a few hours each day and control some equipment. I've got the ability setup to remotely control the equipment, but I need a dedicated camera on an engine tach and pump presser gauge. My original plan for a remote camera is not working and time is running short, so I thought I could end up using the new MB I got recently with the integrated webcam, and VNC into the computer. I tried it out today and it seemed to work well except for two things, both related to the display being on.
1) There is no power available so maximizing battery life is a must
2) I was getting a bit of a glare off the gauges from the screen that made viewing a bit difficult.
I think both would be solved if I could run the MB with the screen off, but I don't know if this is possible.

Earlier this summer, my iMac suffered a crashed Logic Board. Thankfully AppleCare took care of the $900 it would have cost to replace it.
Earlier today I put my MacBook Pro to sleep by closing the lid. About 2 hours later I went to open the lid and the monitor never turned on. The white light is on in the front. I restarted it and the light remained on and the monitor did not turn on. I unplugged all devices and restarted and still no luck. The Number Lock key lights up and the sound works fine - but no display.
Could this be another failed Logic Board or a failed chip set from here:[URL]
Are there some other types of methods I should try (PRAM Reset, etc.) If I have to bring it in, thankfully AppleCare covers this Mac for another year. What horrible luck - college just started.

I'm currently working out a plan to use my old Macbook as an AppleTV equivalent- I've found out about atv4mac and it sounds ideal. However, the laptop will spend the whole time running with the lid closed, is there any way to totally turn off the monitor? I can turn the brightness down all the way, but it's still on, seems like a bit of a waste!

I know that the web have a lot of tips similar to this that i will ask, but i couldn't find no one exactly with what i want
I bought a new monitor, and mini-dvi adapter, an external keyboard and mouse to plug on my macbook
I would like to know how to turn off the macbook display without having to close it. I want to know that because if i don't close the macbook, both displays are on. If i close the macbook, the computer goes to sleep and then i press some keys on keyboard and the mac wake. In that point, if i open my macbook the display is turned off like i want. But i don't want to have to close the macbook all the time, and i don't want to leave the macbook closed because closed the temperature goes high.

My goal is very simple for the time being.... run my 2 LCD monitors together so I can have double the desktop space. I plugged everything in properly and it seemed to work right away at my pleasure. However, then I quickly started getting real pissed off.. If you guys have ever looked into the "displays" option when you have a mac hooked up to any other kind of external monitor, there is a "mirror displays" option. When I have these 2 monitors running default mirrored, and go into "Displays" there is no option for unchecking the mirroring box. In fact, there isn't even the "Arrangement" tab. Just "Display" and "Color".

WITHOUT closing the lid, because i like using the touchpad. i know that you can turn the brightness all the way down, but sometimes windows from the main screen randomly open on the other display. and it also slows down performance. i want to turn off the 13" screen as if the lid was closed. that way, the mac doesn't even see it.

I have seen people all over the internet saying that their MBP monitor would not turn on, but I have not seen my situation before. I used the computer a week ago (it's a work machine and I'm a part time intern) and both the external and internal monitor worked. I shut it down and when I came back the computer booted up to the external monitor but gave no video on the internal.
I shut down, removed the external monitor (connected by DVI cable) and rebooted. Nothing came up but when I connected the external again it worked fine. This had happened before, but when I shut down and rebooted without the cable connected it came back on immediately. I'm just hoping its not a bad graphics card or something that needs to go in for warranty.

I have a Mac Pro 8 core that is almost 2 years old. Still running Leopard and 10.6 I believe.
This morning all worked great, and after a lunch break the 30" Apple monitor won't turn on. The power lights on the monitor. We substituted an older 22" we have and that won't work as well.
We tried both video inputs on the back on the computer and still nothing.
When we turn on the computer we hear the Apple signature sound and even though there is no visual on the monitor, this computer has a QuicKey keystroke to shut down the computer and this works.
Is this a graphics card failure?

So I bought my 13inch MacBook Pro Retina two weeks ago. 70% of the time when opening the lid the screen will not turn on but my keyboard backlight will. I then have to either close the lid and open again or press the power to put the system to sleep and wake again. It seems the system is working fine just not the screen.Â
I have tried the SMC and PRAM reset which seemed to work for half of the day, now the problem is back.

Is there a simple app, key combo, or a way I can use AppleScript, to turn off my monitor manually (resume on mouse move)? I need something like this for the automatic input switcher on my monitor to work.

I am seriously considering the possibility of using the 27in iMac as an external monitor with my MBP when I am home and need the extra monitor space. That would also allow my family to use the iMac when I am away at work or out of town. Since my MBP has a Mini DisplayPort, it should be as easy as connecting the MDP from the laptop to the MDP on the back of the iMac and then connecting the USB for audio? However if the iMac is turned on, how can I use the monitor without the actual computer running at the same time?

2012 Mac mini with a Thunderbolt display, recently updated to 10.9.3. Normally, it's set to never sleep, but to have the display turn off after 15 minutes with no screen saver. Since the 10.9.3 update, it won't turn off at all. I've tried changing the settings back and forth with no results. I've also gone into Library->Preferences->SystemConfiguration and deleted the PowerManagement.plist file.Â
I can turn the power off with control-shift-eject, but I'd rather it happen automatically. Is there something else new that came along with 10.9.3 that is preventing monitor shutdown?
Info:
Mac mini (Late 2012), OS X Mavericks (10.9.3)

Is there a way to disable the �pinch open and close� feature on a MBP trackpad? I swear, it�s going to put me in therapy. Every time I need to scroll through massive spreadsheets for work, if my fingers separate by even a hair, the trackpad reads it as a pinch, then the document suddenly balloons to massive proportion or shrinks to infinitesimally tiny print. Seems there ought to be a simple way to turn the thing off, but for the life of me, I can�t find it.

I knew everything was working fine on my Macbook Pro 2.4 GHz i5, 8gb ram, Mac OS X Version 10.7.3. I loaded up my Mac this morning and tried to open Activity Monitor but wont open. When I drag the application to the dock, there is no icon picture for it. I looked on the internet and it told me to load up Console, which I then found done the same thing.
In Utilities I realised the App 'Podcast Capture' was also missing its icon, but since I do not use that, I am not worried. After looking through google again, I ended up using FirstAid and repaired the disk and permissions. That still made no difference. Finally I then decided I could delete the .plist from preferences, to then find neither of the files for Console and Activity Monitor were there? And I had not deleted them.
Once last thing, in Terminal, every time I open it, it comes up with, bash: /usr/libexec/path_helper: Unknown error: -22
Not sure if this relates to it in anyway? The only thing I know that may have effected it was setting up a Minecraft server which I had to use a chmod a+x (file location). Which I thought gave it the commands. Didn't work anyway, but whilst in the middle of doing that I realised all these other issues.

iMac G5 17" iSight
1.83GHz
2GB 667MHz SDRAM
My monitor has turned off and will not come back on. Clicking noises and a slow operating speed occurred a few days ago. I have tried this SMU Reset Process below:
from [URL]
1. Turn off the computer by choosing Shut Down from the Apple menu, or by holding the power button until the computer turns off.
2. Unplug all cables from the computer, including the power cord.
3. Wait 10 seconds.
4. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
5. Let go of the power button.
6. Press the power button once more to start up your iMac.
Upon completing step 6, the computer turns on only to feature the fans spinning at maximum speed and still no monitor display.
Is this a Logic Board issue? The iMac was purchased for $1700 in 2006. Would repair costs be so high that just buying a new iMac would be the better way to go?

**Intel Imac 24 in. 2.4GHZ Core 2 Duo (NOT G5...my bad)
I know the "Using imac as external monitor" topic has been adressed in previous posts and it apparently can't be done. But this is slightly different.
I have this Imac G5 24" that is currently out of order. (won't detect hard drives when powered on 90% of the time and when it does i am experiencing ridiculous lag and random shutdowns...not to mention crazy overheating)
I sent it to tech support and after changing the hard drive, power supply etc.. and still not seeing any improvement i just stopped sinking money in repairs and got a new imac.
So now i just have this useless imac laying around and i figured i might as well try and recycle it into a secondary monitor.. I don't mind hacking it open since i have nothing to lose. I was just wondering if it could be done and if so would it be very complicated? I would rather pay a few hundred dollars in wires and IT than buy a cheap external monitor since its already a decent quality monitor and it matches the new imac

I have my 09 mini connected to a Dell E177FP and I have the energy preferences set to turn the display off after 15 minutes. The problem is that the display never turns off. It just sits at the "check signal" screen as if it was not plugged into anything. How can I get the monitor to go into standby mode?

I have dozens of large PSD files (well 200 of them each abt 200mb) on a network drive folder that I need to access frequently. Access to these is really slow because it seems to want to create thumbnails every time I access that folder. I don't need thumbnails as all the files have a strict naming convention so I know what I want by name. Whatever view I use to load files (I'm using Photoshop CS5) (list, column, icons) it always tries to put a little thumbnail preview next to the file name. Is there something I can type into Terminal that will stop it doing this.
