IMac as an external display, problem with trackpad/mouse pairing

Hi,
I am trying to use the imac as an external display for a macbook air, which is well supported/advertised by apple.
I can toggle the display easily between the imac and the macookair, the problem I’m having is that I only have one wireless keyboard and one wireless trackpad. As I toggle the display, the paring/unpairing of both trackpad and mouse is a real hastle becuase I have to manually go into bluetooth preferences and adjust the settings for both devices.
Anyone using the imac as external display with an idea/suggestion how to make this process more friendly?
Thank in advance for any help.

I don't think you can. Wish I had better news. Target display mode for non-thunderbolt 27" Imacs worked OK. I have done it myself on a late 2009 iMac. The new iMacs can only go into target display mode when connected thunderbolt to thunderbolt. So a new macbook or macbook air can do the trick but your dell can't. What you can do is remote desktop or VNC to the dell. Now your dell screen will show up but in a smaller window.

External display problems with snow leopard

I just upgraded from Leopard to Snow Leopard on my Macbook and it's created lots of problems with my LCD external display:
- The display won't work at its native resolution (1680x1050) - it will flash up an image for 1/10 of second and then go black. I can only get it to work at a lower resolution, which looks AWFUL.
- If I try to start up my Macbook with the lid closed and the display connected, the display won't work at all (it jams on the start up screen). It only works if I keep both of them running
I never had these problems when using Leopard. I've searched lots of forums and found that many people are having similar problems with external displays. Apple still haven't fixed the bug after repeated efforts from people to get if fixed.
Here are some threads (now closed) on this if you're looking for solutions:

Common suggested fixes are:
- Force OS X to use LCD font smoothing (does not work for me)
- Clear the PRAM on start-up (does not work for me)
- Delete /Library/Preferences/com.apple.windowserver.plist (does not work)
- Change energy management setting to high performance (only works on graphics cards in Macbook 15" and 17").
From reading these forums it appears that this is a well-know bug. Has anyone else got any suggestions to fix this? And why hasn't Apple fixed this yet after so many people bringing it to their attention? It's clearly a bug that wasn't in Leopard.

I'M FED UP WITH APPLE! They've always been a little shady, but the last half of 2010 took the cake!
First it was the iPhone 3g "upgrade" to IOS4 which was garbage and killed my ability to use the 3g until I figured out how to crack the software, wipe the thing clear then reinstall the original software. Next up was purchasing the iphone 4 as a Christmas gift for someone running tiger on their mac, only to find out that the iphone 4 doesn't work on tiger when they tried to sync their contacts - and then having to rush out and purchase snow leopard so that they could enjoy my gift. Then I install Snow Leopard (note - I purchased the family pack) onto my own leopard-running(10.5.+) powerbook only to have the external LCD display I've been using for years suddenly stop working.
Oh, okay, to be fair, it works IF I RESIGN MYSELF TO SET it to "mirror image" (which defeats the purpose of having multiple displays) and drop the resolution down to a pathetic, unsharp, nearly distored setting that is almost painful to look at knowing that this monitor was just A COUPLE OF DAYS AGO showing me crystal clear images.
Then I exhaust myself trying to find a fix only to discover that APPLE in their infinite brilliance (AKA - their torture of loyal customers) knows of the issue - worked it out - then created an update that created the issue all over again. I'm so done! No more macs. I'm going back to the evil land of PCs. At least there, you know you're getting crap, it doesn't sneak up on you after getting you to trust it time and time again.

MacBook external display problem with Panasonic projector

MacBook (September 2006, Intel 945) with Boot Camp and XP Pro won't display externally from Boot Camp to a Panasonic PT-DW5000U projector using VGA (via the MiniDVI-to-VGA adapter/dongle). I tried 640x480x8-bit and 800x600x16-bit and 1024x768x16-bit. I tried unplugging and replugging the adapter. I tried shutting down and restarting into Win XP while all video cabling was connected. I tried pressing F7, Fn+F7, Shift+F7, FnShiftF7, as well as other key combinations involving F7. I tried checking the checkbox called "Extend my Windows desktop onto this monitor." I installed Apple Software Update 2.1. None of these troubleshooting attempts worked. It works fine in OS X to the same projector (using the same VGA dongle). And, while Win XP starts in Boot Camp, the projector displays the Windows XP startup screen (black background and blue progress indicator), but after about a minute that disappears, I get a login dialog on the laptop screen, and the projector then displays only a blank blue screen.
Other displays: It works fine with Boot Camp to a Samsung SyncMaster 940T monitor using DVI (via the MiniDVI-to-DVI adapter/dongle). It works fine with Boot Camp to a Panasonic LC50 monitor using VGA (via the MiniDVI-to-VGA adapter/dongle).
We also have Panasonic PT-D5500 projectors, but I haven't tried them yet.
1. Is this a problem in the Intel drivers supplied with Boot Camp?
2. Are there settings on the projector that need to be set to make it work?
3. I'm also now missing the Intel system tray icon that looks like a slanted computer screen -- how do I get it back?
Any suggestions? Thanks!

Based on the substantial research I've done regarding this issue, here's what the problem could be (without me knowing more):
If your working with an integrated graphics card (Intel 945?), chances are that it doesn't support the "resolution" of the projector - which is information embedded in to your other devices. Furthermore, the "refresh rate" is another piece of information usually "embedded" in to the device your connecting to, and the projector may not have either piece of information accessible to your card, or, vice versa.
Additionally, the drivers required by XP to make it all happen while using your particular video card, may not be installed. Basically, it could be a driver issue as well.
I wish I had a solution for you, however, everything I've read seems to conclude that XP within boot camp has little or no support for external displays (especially when talking about larger resolutions).
Humorously, when I addressed the "Mac Genius" at the Apple Store regarding this question, he told me to go buy a PC - so I did. Already have a Mac Pro, needed a laptop...

Problem with Magic Mouse pairing

Hello Apple Support Communities
I have used a Magic Mouse for some time, maybe now an year. But I started having this problem today.
When the Magic Mouse did not connect with my MBP, I removed the mouse from the Bluetooth and tried to put it back.
But the Bluetooth Setup Assistant is saying that the pairing did not work, and asked for a passcode or a different pairing method.
Here's a screenshot:
Also, I tried using the System Prefrences and click on mouse to set up my Magic Mouse, but it said the same thing; pairing failed.
Here's a screenshot:
Is there any solutions to this problem? I hope that you can get me an answer fast, as I use Magic Mouse a lot with my MBP.

Not knowing what machine you have, it's age, and its current OS X and version doesn't help people help you. Please could you fill in your profile.
Do you have, or know someone who has a wired mouse?

How do I use my 2011 27" iMac as an external display for a pc?

I just bought a 27" imac for my home, and was also planning on using it as an external display for my work Dell Laptop running Windows 7.
The Dell laptop has a displayport output, so I was planning on getting a displayport <-> minidisplayport cable, and using the iMac in target display mode.
I would simply plug the minidisplay end of the cable into one of the iMac's 2 Thunderbolt ports. Seemed fairly simple.
Except now it seems from what I have been reading that 2011 iMacs DO NOT WORK in target display mode unless they are connected to another Thunderbolt source. This leads to me two questions.
1. Can anyone confirm or deny this? If this is true, does that mean I cannot plug my Dell's displayport into the iMac's Thunderbolt port as I described above?
2. If #1 is true, is there any other option? Are there any adapters that I can use to turn my Dell into a Thunderbolt source for display purposes?
If I can't resolve this I will have to return the iMac
Thanks very much.
David

David,
Sorry you can't use the 2011 iMac as an external display to your PC. The feature you are referring to is called Target Display Mode and works on 2009 & 2010 27" iMacs. The 2011 machines use Thunderbolt as you know however they do support external displays that are not Thunderbolt displays. So for example if you wanted 2 displays on the iMac you can easily do that with either Mini Display port to DVI or MDP to VGA or even HDMI. MDP is the same size as Thunderbolt and this will work fine to drive a display, TV or even a projector.
I'd recommend reading Apple's explanations at Target Display Mode 2009 & 2010 iMacs & Target Display Mode Mid 2011 iMacs.
Using a Mac as an external display for a Windows machine to me seems like a horrible waste of a Mac. Why not enjoy the iMac and if anything run Windows on it and get rid of the PC?

Using a 27-inch iMac as an external display for my macbook air

I would like Using a 27-inch iMac as an external display for my mac book air.
i bought a Mini DisplayPort to Mini DisplayPort cable, it's the Belkin Mini DisplayPort to Mini DisplayPort cable on apple store.
I connect my imac and mac book air with this cable but the screen of my mac book air don't appear on imac screen.
where is my error ?

Morning seal, my experience suggests the latter of your two posts is the correct one. I have a 27" iMac with a mini display port (a 2-year old one, not the newer one with thunderbolt); and a brand new Mac book air with thunderbolt. I connected the two with a Belkin male-male mini display port to mini display port cable, and it works fine - press command f2, and the iMac acts as display for the MBA.
The irony here is that the folks at the apple store in Paris assured me that this would NOT work, and that I needed to buy a €999 thunderbolt display to connect to my MBA. I thought I'd try anyway, since I had the cable to connect a MacBook pro to the iMac anyway... Glad I did.
Bottom line: yes, despite all the confusion, the new MacBook air will connect to the minidisplay port of an older iMac 27"; and the cable it needs to do that is the older minidisplay port cable, not the thunderbolt one.

Can I connect to iMac 27" as external display?

I'm considering buying 2 iMac 27" to run Windows 7.
Can I connect these two together so iMac 1 can use iMac 2 as external display and visa versa.
In other words... is the mini display port both for input and output?
If yes... does this work under Windows 7 as well?

I just love Mac hardware, and an iMac (two in my case) on a desk is just such a nice clean setup, with only one cable. Just counted 16 cables for my current PC mini tower setup with 2 screens - don't ask
Just so you know, I'm well aware of Apple's "cableless" marketing for this thing. But on my new iMac, I actually only have a single port, the FW800, that doesn't have a cable sticking out of it.
But Mac OSX is just not a nice operating system IMO
At least we can use you as an example of a 100% legitimate Mac owner of a Windows OEM install.
Anyway... I just ordered 2 x 27" iMac's. If i somehow succeeds in getting them connected in Windows, I'll post here... if not feel free to ask me, in 6 months.
Please do post back, because if someone tries it, then everyone will know if it works. I have seen reports of a PC driving the iMac display and I have done it with my MacBook Pro. I'm still not 100% sure that two iMacs will cooperate in this way. They both have the same cable connected to the same input/output port. Which one is the target? I have never heard of Windows or any PC hardware having the ability to convert a video port to input, so Windows would have to be the broadcaster. You may need MacOS X to detect the input and use it instead of trying to send out its own signal. Hopefully this won't short out the video circuitry on both.
And in 6 months when you are reinstalling Windows to clean off all the malware, you can still use the Mac machine

Display Problem with my Mac Pro and LG Flatron Wide Monitor in Mountain Lion

After upgrading to Mountain Lion, my Mac Pro has display problems with my LG Flatron display. The image is displayed with a black bar on the right and on the bottom. And the left side of the content is not visible. I tried every resolution available in the Display System Preferences, they are different in terms of how big the black bars are, and what part is not visible, but none of them are correct. I held down the option key to try to detect displays or switch to resolutions that are not normally available. When I restart the image is lined up with the display, but if the display ever goes to sleep or gets turned off, the image reverts to being off center, and the only way I can get it back is to restart... The interesting thing is that this monitor works fine with the same machine if I reboot using BootCamp into Windows 7. The Monitor also works fine, connecting the same connector to a Mac Mini, although that mac mini is running 10.6 and not Mountain Lion. I've reset the SMC and restarted countless times, I don't see any other levers to pull or things to try...

That card is for a PC it may not give you Startup and Option-Boot screens.
The 7950 "Mac Edition" card has a very distinctive look:

I need to download dell drivers to a jumpdrive connected to my iMac. Will this cause problems with my Mac?

I need to download dell drivers to a jumpdrive connected to my iMac. Will this cause problems with my Mac?

Thanks. These drivers are for the audio, etc. for a dell laptop I purchased used. ( Needed something cheap for a training video that would only run on Windows. Tried Emedia player but picture was too fuzzy.) Dell support said I should contact Apple support for instructions on how to get the drivers onto the jumpdrive. Any tips on doing that?

The cursor on my iMac freezes, and I cannot do anything unless I unplug the computer. It is NOT a problem with the mouse or the keyboard ... it is internal. How do I fix this??

Sorry to say but your imac g5 logic board has bad caps. This was a problem apple had and issued a out of warentee fix but that has now expired.
The cost to get this repaired is more than what you could find another used imac for.
I would suggest you get some details before you rush to make a diagnosis. You have absolutely no information to base this on. I see you're hitting up on numerous threads all over the place. Quality, meaning several good posts with reliable advice, is much more worthwhile than quantity.

I downloaded OS X Lion on my iMac and I'm having problems with my computer waking up after hibernating. I can get to the login screen but my mouse will be frozen. The only fix's is a hard reboot. Any help would be great!

Try resetting the SMC and the PRAM.
1. SMC
Read this and follow the instructions for your kind of mac:
http://support.apple.com/kb/HT3964
2. PRAM
Follow the procedure below:
1. Power down the machine.
2. Locate the following keys on your keyboard in preparation for Step 4:
command–option–P–R
3. Press the ‘power on’ button.
4. Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
5. Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up as it should normally.

Display problems with Kwin on intel hardware

Hi all,
Since the latest update of xorg and intel drivers, I have a display problem with kwin's expose-like feature. Before I file a bug,
- Is anyone experiencing the same problem? Do you have a workaround?
- Does anyone know what could be at fault?

Ctrl+F11 works "fine" on my system, even though it crashed kwin the first time I tried it :-)
Well, that's a very tough question! I was thinking to fill a bug report in Arch's bugtracker, although I also think it is an upstream bug.
