Yellow line on my 27-inch iMac
This line just appeared. Yellow line 5-8 inches running vertically on my 27" iMac 2010.
It may be the graphics card failing. You should immediately take it to your local Apple store or Authorized Service Center.

I developed a vertical yellow line on my mid 2011 iMac - anyone else have this issue.
My iMac developed a vertical yellow line on the left side of the display. Any easy way to tell if it is a logic board or ?. Anyone have idea of cost to repair or if this is a known issue? I have 2 older iMacs that have great displays with no issues. Screen shot shows the line.
A screen shot is 100% software. If memory serves me to get one its Shift Command F3. The use the forums tool for integrating into your post.
Have you run Apple Hardware Test in Extended mode? If not do it 3x back to back. If an error code appears take that with you on your visit to the Apple Store or AASP. Apple does not publish these codes only the store or AASP can accurately translate.
Good luck and By the way next time get Apple Care, small investment but huge return on issues like this. -
I have an IMAC 2006 that was working fine until I installed new software which was Snow Leopard a couple of months ago. Now I have a dotted yellow line running down the side of my screen. I call the 800 for apple and are told they can't help me because my comuter is to old!? So I call an apple store and they can't help because my computer is to old!? So where do I go now? It seems all APPLE is really concerned with is what they can sell you, not helping you fix what you already have this is the worst customer service ever!! I really don't think I would by another apple product based soley on their customer service! I mean I bought a computer that was over $1300 and now that it's too old no one can help me?? Does anyone at APPLE now anything about comuters more than 3 years old?!!
Hello, just other users here trying to help, but I do feel your pain.
Have you blown the dust out of it lately?

I'm VERY happy with the results (fast!). However, the really strange thing is this - there is now a thin yellow line, way over on the right side of the screen, which goes from top to bottom, and stays there no matter where I go or what I do. I've never seen anything like this! It was not there before I did the upgrades. Anyone out there ever heard of such a preposterous thing ~ or have any ideas on how to get rid of it?
Hello Mark,
It's going to mean a lot of reading but you should study the 'More like this' legend to your post's immediate right. >>>>>>>> plus some of the links within each.
The problem is well explored with much guidance on what to do and where to go. -
I have a vertical yellow line down the centre of my iMac g5, is there any way to fix this issue?
Hi, I've seen a few other forum discusions on this issue, and it seems to have been a recurring problem, I'm wondering if Apple have a software patch available for this issue. Its a vertical yellow line that runs from the top to the bottom of the monitor, other people have spoken about how multiple lines can start appearing once the problem has begun, so I'm concerned that this is going to degenerate. I recently upgraded the OS to Snow Leopard, so I'm wondering is it possible that this may have been one of the issues that people have come across when updating the OS.
How is it connected? Have you tried different port? How about logging in as a different user then trying to mount the drive.

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. -
Just bought new 24 inch iMac, what a monster!
Just got back from Apple retail store in Brent Cross near London in the UK with my new 24 inch iMac.
All I can say is BRILLIANT!!. What a stunning machine. I had a 20 inch that I bought just 3 weeks back, but I managed to get rid of it to buy this new one.
Now that I have it on my desk at home I can really appreciate the extra 4 inches, it seems like a lot more than that.
As the Apple retail store is a 1-hour drive for me I insisted on taking it out of the box and booting it up in the store to check it out before the drive home. It was just as well that I did as there was a single stuck (black) pixel in bottom right hand corner. This would not bother most people, but I do a lot of Photoshop work and I can only imagine that I would be constantly trying to airbrush a speck out of a picture, only to discover that it was a stuck/dead pixel.
Anyway, the salesman said no problem and got me another one, which I also checked there and then, second one was perfect.
Anyone who has a 20 inch, get rid of it and buy a 24 inch straight away. They are just awesome.
Even the staff at the Apple retail store were standing around me in absolute awe as I was checking mine out and filling in my personal details, as they did not have a demo unit on display at this time.
Other people were standing around too, a little crowd gathered; I felt like an Apple God for a moment there
The edges are not dark like somebody else mentioned, mine is nice and bright edge-to-edge. In fact is is brighter than my old (3 week old) iMac 20 inch as I have to reduce the brightness on this new 24 inch monster a little bit more to get a nice brightness that I'm used too.
I put in an extra 2 Gig of ram (2 x 1 GB sticks from my old 3-week old iMac 20 inch model), but bought the standard 24 inch model with standard graphics card. Didn't see the point in better graphics card as I don't do gaming, just inDesign and Photoshop on this machine.
This screen is also 1920x1200 so it is TRUE HD for playback of future 1920x1080i or 1920x1080p Bluray or HD DVDs, nice. If you think about it, if you popped to a local store and bought a HD-Ready TV with this resolution it would cost you a lot more than the price of the 24 inch iMac so it's like getting a HD TV with a computer thrown in for free, only cheaper
Had it turned on now for about 3 hours and have been spinning the hard drive a lot as I transfer a lot of old files from external Firewire HD and it is warm near the vents on back/top, nothing excessive though.
The fan is ever so slightly louder than old 20 inch, but again, negligible.
Well I'm off to play some more and test some DVDs etc.
In the meantime they are fantastic machines and I highly recommend them to everyone.
Buy one today, I don't care how, just get one!!!Hey guys, didn't mean to scare anyone with that dead-pixel thing. I've had about 7 Macs over the past 5 years (since moving over from the muddy waters of Windows) and I've NEVER had a single problem. To be honest I was amazed the first 24 inch iMac I pulled out of the box actually had a stuck pixel and so were the staff. One of them tried to 'massage' it away, to no avail. It was hardly noticeable; I'm just a fussy git.
I doubt any of you guys will take delivery of one with a dead/stuck pixel, this is very rare as Apple only use grade-A LCD panels that have a high quality-control-production-line.
Anyway, howwow, you really must get a 24 inch; here's why.
I had 20 inch and spend a lot of time laying out an A4 magazine in Adobe InDesign. I thought my 20 inch Intel Imac was great until I got the 24. Now I can have a full two-page spread across the screen zoomed in 25% bigger than actual size and still have room for my pallets down the left and right hand side. With my old 20 inch iMac I had to collapse or hide certain pallets away or they were over the top of my page on the top/right hand side, which was a pain.
Another advantage of 24 over 20 is that it is much easier copying files from external to internal hard drives and vice-versa, especially when in Column view as you can have 5 columns on each window; plenty. On my 20 inch I could not get anywhere near this and had to move windows around the desktop to get them into the best space; not anymore.
Two of my friends came (almost literally) to see me last night and when they stepped into my study room and clocked the massive 24 inch iMac they both almost creamed their jeans right then and there. They were speechless; they are both windows PC users, or should I say were. The 24 inches was more than enough to convince them; well, they were both ladies They are heading for Apple retail store as I type this to buy one each. Now we all know how bloody hard it is trying to convert Windows users to Mac, the 24 inch iMac has no problem doing that.
I had a large high-def Quicktime movie playing, 6 smaller Quicktime movies playing, a DVD playing with Photobooth open and a bunch of other things, when I hit the exposé button to reveal them all at once it is just amazing on this large screen.
I've also noticed that running Adobe Photoshop and InDesign on this latest 2.16 GHz Intel Core 2 Due with 2 GB of RAM is a lot faster than my older (3 week old) iMac 20 inch Intel Core Due machine, that extra '2' really pushes Rosetta programmes along the rails a lot faster; it's sort of turbo charged now. This is great for me as I view InDesign stuff in OverView mode (higher res, but slower).
This new machine takes just 31 seconds to boot from a cold start by pressing the power button on the back. Fast or what. Ever watch a Windows user switch on their machine and go have a cuppa coffee whilst they wait
The graphics (and I only have bog-standard card it came with) are brilliant. Pin sharp and I've set up a custom colour calibration for the screen because of Photoshop and InDesign and it is stunning.
Only slight drawback is if you sit too close and are a fast typer, it's like watching tennis as your head looks from right to left as you type across the screen -
Does anyone know when the 27 inch iMacs will ship?
Does anyone know when the new "thin" 27 inch iMacs will ship to California? I ordered one in early December and can't get a firm answer.
If you ordered it when they were accepting Pre-Orders then chances are you'll receive your iMac between Dec. 24th and 31st. But seeing as how you ordered it in December, I don't think that's the case. I'm about to purchase a customized one, so I've been back and forth on Apple's site since late November, and I noticed that in December, the ship date shows January. So I'm thinking that once January 1st rolls around, the ship date on the website might be updated with something along the lines of 1-2 weeks or such. Good luck, I feel your angst. I'm about to order one, but it's already December 26th tomorrow, so waiting till January won't be that big of an issue. By the way, did you go with the new Fusion drive? I think I'm going to. At first I decided I wasn't because people were saying that there was a possibility of files being corrupted because they are being moved around and re-written so much, but I'm not so sure now. I'm thinking I'll try the 1TB Fusion drive, not too worried now because I back up all my important stuff to external HDD. Plus from the videos I've seen, boot time and app load time with the Fusion Drive models is wicked quick.

Yellow Line Down the center of the screen
I have a 2006 17" intel based iMAC running Leopard 10.5.8.
And when I booted it up a yellow line just appeared right down the center of my screen.
I've tried rebooting and zapping the PRAM and running FSCK. I called Apple support and a specialist told me to unplug it wait 30 seconds and restart it. But none of these worked.
Does anyone else have this issue and if so what did you do to fix it.
Oh and my Apple Care Extended warranty JUST expired a month ago.I've got two of them...out of warranty. They do not go away.
They are annoying. Get the screen fixed while it's under warranty -
The right side of the screen of my MacBook Air a yellow line appears very thin and dotted. What can I do to eliminate it? Marco

How do I use an external monitor with 21.5 inch iMac?
I have a brand new 21.5 inch iMac and am trying to hook it up with an older 20 inch Mac cinema via Thunderport. Do I need a special cable. I saw none at my local Apple store. or will it work at all?
Use a Mini DisplayPort adapter for that monitor type.

Hi there,
I'm trying to work out if there is any way that I can use my late 2009 21.5 inch iMac (running OS X 10.6.8; mindisplay port) as an external or second monitor when connected to my early 2011 13" MacBook Pro (OS X 10.6.8; thunderbolt).
From what I've read online, I gather that I cannot simply connect the two with a minidisplay port to thunderbolt cable, as the iMac does not support target display mode. I know I can 'share screens', but this doesn't give me much of an improvement on size compared to just using my MacBook.
Are there any other potential work arounds I might have missed? Any suggestions (or even conclusive answers to suggest I'm wasting my time by continuing to think about it!) would be much appreciated.
Many thanks!Sorry but no, you are asking about Target Display Mode and the 2009/2010 21.5" iMacs did not support that, only the 27" iMacs did. You can read up on TDM in Apple's Target Display Mode: Frequently Asked Questions (FAQ)

2009 24-inch iMac 3.06GHz (EMC no. 2267). I don't get any audio when connecting my Sony HD TV to my iMac via mini DisplayPort. Is there a fix or hardware upgrade? I'm using a Kanex Mini DisplayPort to HDMI cable w/ audio support.
You can connect the audio from your iMac to your TV using a mini jack (like headphones plug) to rca (regular red and white audio connectors used on every TV,DVD, etc) cable.
On your TV, you need to be able to set the audio for the HDMI input you will use to "analog" and connect the rca end of the cable to the analog inputs on your TV. -
What cable do I need to connect my 27 inch iMac to my Cinema Display
What cable do I need to connect my 27 inch iMac to my Cinema Display to have two displays?
It depends on what type(s) of video input you have on your TV. If you've an open HDMI port on your TV, you can use a Thunderbolt (Mini DisplayPort) to HDMI adapter and it will carry the sound also. See -> here.
Good luck,

Spinning beach ball woes on 27 inch iMac
We have a mid 2010 27 inch iMac (and also a late 2010 13 inch MacBook Air, from which I am writing this post). About 6 months ago it was starting to get spinning beach balls, which I attributed to not having updated the OS (then 10.7). Having upgraded the Air to Mavericks with success, I also upgraded the iMac to Mavericks, and the beach balls got much, much worse, rendering the thing nearly unusable. I cannot for the life of me figure out what the issue is, particularly because the Air, which is about the same vintage, is working great under the same setup. Can someone who has not been staring at this problem for 6 months help?
Here's what I've got:
As I mentioned, mid 2010 27-inch iMac, 1TB hard drive, about half-full, backing up to a 2 TB Time Capsule.
We have two wifi networks to cover the whole house; one is integrated with the cable company's provided router and sits in the basement, and the other is the Time Capsule hooked up to the cable company's VoIP router upstairs. Because you cannot use the Time Capsule to extend an existing network if it is not an Apple network, I resorted to setting each wifi network up independently (separately connected to ethernet). My Air navigates this just fine, as do our iPads/iPhones, and I don't notice a speed difference between the two networks (assuming I have equally good reception wherever I am).
Notably, the Time Capsule seems to randomly stop broadcasting wifi every now and then (at intervals of a few days to a couple weeks), which requires a restart to get it working again. (This could be totally unrelated.)
The iMac was at 10.7 when the beach balls started; upgrading to Mavericks made the slowness/beachballs worse. As I noted, Mavericks did not cause any trouble with the Air.
The beach balls seem to coincide with a complete stall in everything the computer is doing. After the stall ends, the computer can be fairly speedy, so it's as if it pauses for several seconds to a minute or so to think very hard, and then goes back to its business.
There is usually a slight improvement if I shut down and boot up again, but it gums up pretty quickly.
Here's what I've done:
Started with 4GB RAM; added another 8 (total 12) after this all started. Equally bad before and after.
Stared at Activity Monitor and Console for long periods of time while watching for beach balls to try to detect a pattern.
In Activity Monitor, memory pressure is fine (esp. now that I added 8 GB), no swap used. The two worst offenders under CPU usage seem to be kernel_task or WindowServer, but they are not always monopolizing the CPU at the times when it is stalled.
In Console, the main two patterns seemed to be a frequent WindowServer "updates forcibly disabled" error, and what seemed like a constant browsing for wifi connections even though the computer was already connected to wifi. However, I couldn't figure out what either of these meant or what might be done to fix them.
Used disk utility, repaired permissions, verified disk, etc. - everything was ok, although some permissions were repaired.
Used third-party utilities, Onyx and iDefrag, to try to verify disk and clean things up. No significant problems detected, and no improvement.
Various other methods of cleaning up -- eliminating old software or files that aren't being used, emptying trash, taking extra files off the desktop, etc. In particular, having read that Mail might have issues handling Google accounts, I eliminated a heavily-used Google account from Mail and got a separate, lighter-weight third-party app to handle that account. That did seem improve things at first, but we seem to be back to slowness and beach balls again.
Final, last-ditch effort: backed up and then erased hard drive and (after another Disk Utility verify - still fine) did a clean install of Mavericks.
It took several attempts to download the installer using the Time Capsule network (kept stalling); switched to the other (non-Apple) wifi network and it downloaded and installed fine.
However, after the clean install, although it was not nearly as slow as before, amazingly, I still had spinning beach balls and hanging without having installed anything other than the OS.
I made several attempts to get into the backup to selectively reinstall files. Could not mount backup using Time Capsule -- option-clicking and selecting "Browse Other Backups" did not actually get me to the other backup. Using Migration Assistant, could not get the backup to load, or the loading was taking an inordinately long period of time, so I gave up. (Also, every time I tried to quit Migration Assistant to try to discover the problem with the backup loading, it hung and I had to hard-restart.)
So, since the clean install did not seem to fix the problem, and I was starting to worry about not being able to get to my backup, I have gone back to just restoring from the Time Capsule. It's telling me this will take over 200 hours.
The one thing I haven't tried is shutting down the computer, lugging it upstairs, and connecting it to Time Capsule via ethernet, at least for the restoration. I will do this if I leave the computer overnight and it's still not done in the morning.
I've done much searching of these discussion boards, and tried everything that seemed like a possible culprit. What am I missing?
