Mac Pro :: How To Deactivate One Of Two Displays Under OS X
Oct 15, 2010
First, I need to say that, regarding my problem, I wasn't sure if I should post in this section or in the 'MacOSX' one, but like I'm facing this problem on my Mac Pro 4,1. So, I have a 8-core Mac Pro 4,1 with an Apple HD4870 to which are connected 2 screens: The main one is a Dell U2410 (1920x1200, via mDP to DP adapter) that I use under OSX for photography retouching with DxO. The other one is a 27'' (1920x1080, DVI) I only use for gaming under bootcamp.
When under bootcamp, I only need to turn off the Dell and the desktop is resized for only 1 display. My problem is that, under OsX, even when the 27'' is turned off, the desktop is extended to this display, I can't find a way to deactivate the 27''. I can't even set the displays as 'mirrors', as they have different heigts in pixels (1200 vs 1080), and then I get a Dell resized to 1080. The only solution I have right now is to disconnect the DVI cable of the 27'' when using the computer under OsX.

I have two annoying issues and hopefully one of you can help. i have looked around and cannot find an answer to my question, especially my second one (which i think is connected to the first one). I am using Safari 5.1.3 and OS X 10.7.3. One of the accounts works perfectly, the other has two issues:
1 - Safari will always start with the same set of old windows, even closing some of them and then reopening safari will always get us to the same old set of windows. I understand the (new) standard behavior is that if i open windows A, B and C and then quit Safari, at reopening it will open the same windows A, B, and C. If i now proceed to close window (or tab) C and then quit Safari at the next opening i shouldbe presented with A and B only. This is not the case for me, i am presented still with A, B, and C. I can add to the windows but not subtract. Clearly something is wrong here. Thoughts?
2 - Trying to debug problem 1 i decided to close all the winodws in Safari, then in System Preferences-General uncheck the "Restore windows when ..." and so i hoped that closing Safari and reopening would get me to just the homepage, but this was not the case and i was presented with the same old set of windows. This is easily explained by the fact that under system prefs-general the box i had unchecked was still checked. It lets me uncheck it but does not retain it.... I obviously tried rebooting to no avail.

How to deactivate Photoshop Elements 6 for Mac? I want to uninstall PSE 6 but the uninstaller tells me to deactivate PSE 6 first. However, there seems to be no option for deactivation in the applications installed with PSE 6 (i.e. PSE 6 for Mac itself, Bridge CS3, Stock Photos CS3, Adobe Help Viewer 1.1). I have tried to search the web and Adobe's knowledge base... with no luck. Search in PSE 6's internal Help returns one result for 'deactivate' - but it's something about editing pictures. There's no 'Deactivate...' under Help menu.

I've decided to remove Windows 7 from my iMac - the version installed is the 32 bit version, and I want to install the 64 bit instead as I've just upgrade to 8GB of ram (it's the 27 inch model). Do I just remove the partition via Boot Camp, or do I need to deactivate the serial number somewhere first?

I definitely need to get rid of "Faces" in iPhoto. I don't need it and it is making me crazy. It shows up when I am looking at my photos at places (like on the ground, sky, etc.) where there is simply no face. AND if there is a face I don't want to see any names or pop ups from "Faces" on my photos.
It seems Apple again know better what their customers want and decided for them to have this stupid feature! It makes me really sick!
In case there should be no solution to get rid or "faces" I will just use another software and forget iPhoto.

I think this post would fit in the Hardware/Notebook-section as well but since I am looking for a OSX workaround, I will post it here:
I have a problem with the sudden motion function in my PowerBook. When switched on, the SMS causes to switch off the internal hard-drive at random, even if the Laptop stands on a perfectly still and flat surface. This results in interruptions that make it impossible to work with the computer.
I already had this problem when I was running Panther (10.3.9), and deactivated the SMS with the "pmset"-command using the Terminal at the time. As long as I was running Panther, this workaround worked perfectly for me, I had no more hard-drive-interruptions.
Later, however, I made the Upgrade to Leopard (I skipped Tiger), making a clean install after formatting the PowerBooks hard-drive. Now the SMS was active again (and displayed "active" in the System Profiler) and the HD-interruptions were back.
So I tried to deactivate the SMS with the "pmset"-command - this time without result. I can set the value of "sms" to 0 and back to 1 all right - the Terminal shows the corresponding value when prompting "pmset -g".
Unfortunately this has no effect to either the hardware (the interruptions are still there) or the System Profiler (is displays "active" for the sms, regardless of the value that is shown when using "pmset -g"). I am aware that the variable was altered from "ams" to "sms" from Panther to Tiger (and subsequently Leopard), but neither "pmset -a ams 0" nor "pmset -a sms 0" would work.
To exclude the possibility of a real hard-drive-malfunction, I bootet the Powerbook from an external Firewire-Drive an with my an Panther-backup. After making some testing with accessing the internal HD (it worked fine), I looked into Panther's System Profiler and saw that the SMS was deactivated as expected.
I then experienced something strange - when rebooting Leopard, the sms-Status in the Profiler still was "inactive" and the PowerBook worked perfectly again. I was quite happy and made some updates. However, somehow the status was set to "active" again after some reboots, along with the malfunctions experienced before.
I wanted to find out, whether this "reactivation" had something to do with one of the updates (I brought the system up to 10.5.5 at the time) and booted the old Panther again. The sms was inactive again, again remainded inactive after reboot with Leopard.
I tried to reboot with and without power plug, I even made a PMU reset - the SMS remained inactive (which was good and made me hopeful again). However, after I switched of the Notebook and bootet again a few hours later, the sms-Setting in the Profiler was "active" and the Notebook was again not working properly.
Is there any possibility to access the sms-setting apart from "pmset" in the Terminal? Where does the system profiler derive the status from?
I want to deactivate the sms for good and at the moment this apparently works only in Panther (and I really don't want to downgrade to 10.3 again). I don't want to have it repaired since I think this would mean to replace the Logic Board which is a much too expensive investment for a 4.5-year-old Notebook.

I really don't like the feature of gmail where it saves your sent messages into the inbox. Instead, I would like them restricted to the "Sent Mail" folder so I don't have to sift through my own messages I sent. Does anyone know how I can do this?

As I wrote in another thread my Macbook has both the whining and the mooing, and it's really getting to me. I'm turning it back in, and hope to get a new, flawless one.
However, I've discovered another problem with my Macbook...one that I haven't read about anyone else having: my battery doesn't work.
There's an x over the battery indicator in the top right corner, and when I click on it it says "no batteries available". If I disconnect the charger it shuts down after a second or two.
I've tried to start it without the battery, and then turn it off and put the battery in it again. No change.
Considering that I'm turning it in it doesn't really matter, but I thought I'd throw this out there to let you know that the noise issues aren't the only problems with the Macbooks.
If anyone has any ideas about what I can do to fix it I'll be happy to try, seeing how I won't have time to take it back until saturday.

just updated to LION 10.07.3. / MacPro 3.1 The two displays run fine before under 10.5. (Samsung Syncmaster)They are conected analog, because the digital inputs used by another MacPro (The system is configered to switch just the inputs of the both displays beteween AVID (digital input) and ProTools (analog input) on different macs) Now upgraded to 10.7 Lion they are dedected as VGA displays. And showing 4:3 screens. Using System Conf. -> displays -> detect displays, they are both detected right as syncmaster. Both displays are automaticaly switched to 1680 x 1050.Great! That ist the right resolution! But only one of the displays is now showing the full screen correct.The other display is masking the screen to a 4:3 picture, so that part of the screen-content is covered under that mask...

I have a mid-2010 Macbook Pro with the Nvidia 330m. Does using Mirror Displays require any less system resources (such as VRAM) than Dual Displays? I mean it shouldn't right (assuming that you use the same resolution for Mirror and Dual) because there is still content on both screens being written to the VRAM?

If i set my displays to sleep in 1 minute (say, if I leave it on overnight, and want it to sleep pretty quickly), they both come back to life after a few minutes. Since they're bright, they absolutely illuminate the room and the S/O isn't too happy with me.
I have an Alu iMac 24", Dell 24", bluetooth mouse, external USB drive, USB keyboard. I tried switching off the bluetooth mouse, and it was no better.

I've mini connected to 2 dell 24" LCD displays thru Y splitter (DVI to DVI/VGA). 1st display connects with DVI and the second with VGA.
Vista (bootcamp) can see both displays and it can extend the desktop to the 2nd display.
Since windows on bootcamp can use 2 monitors and OSX can't I would assume that this functionality has been disabled by apple in OSX or display driver. I know that the windows VGA driver provided by apple (bootcamp) has the dual display disabled.
Here is the question:
Where would i have to look in OSX to enable 2nd display?
