Bootcamp Black Screen iMac 27" (Late 2012) GTX 680 Drivers?

This is easy, same problem for everyone.
Using bootcamp to install windows 7 from an .iso in a USB (just because there is no DVD drive anymore on the iMac), after restart the imac a black screen come up and nothing happen.
I think this is because the drivers for the GTX 680 MX 2GB is missing on the USB.
Where to get them and how to fix this problem?
the solution that apple has right here http://support.apple.com/kb/TS3173 it doesn't work at all, just because the driver that you download from there is for an ATI Graphic card.
How to fix this please.
I bought this very expensive imac because it is so powerfull and I want to use designing software with windows and use at the same time mac OS.
Please don't tell me about Parallels or VMware xD.
Thanks a lot
Regards

Hey, I ran across this, sounds like unplugging it might make the difference? going to try tommorrow, best of luck https://discussions.apple.com/thread/4688499?start=0&tstart=0

IMac 27" (late 2012) GTX 680 MX, glitch and artifacts on the screen.

Hello.
I have a one year old iMac 27" (Late 2012) i7, 8Gb RAM, GTX 680MX, 1TB Fusion drive. I was working at the computer and was away for two hours. When I woke my iMac from sleep mode on the screen appeared glitch and artifacts.

That could happen? This is a GPU problem? Or software?
I am very sad.
It happened a month later after my 1 year warranty expired.

Graphical artifacts with DX11 (and OGL4) on imac 27" late 2012 GTX 675 MX

Hello, dear community! I have the imac 27" late 2012 with graphical card GTX 675 MX.
In Mac OS X 10.8.5 all works perfect. Software, games (Bioshock Infinity), benchmarks (heaven 4.0). But in windows...
I was installed Windows 8, then 7, then 8 again, and every time after installing nvidia drivers (with BootCamp, or manually downloaded from nvidia site) i have some graphical artifacts ("||" randomly on the screen). On win 7 it was only in games (like Bioshock Infinity or Tomb Raider), on win 8.1 everywhere(on desktop and in games). In DX9 games (like World Of Tanks) all perfect, in DX10/11 games (BI or TR) - artifacts. After thousend of tests i run Heaven Unigine 4.0 with OpenGL(other settings the same) in macos and in windows(on 7 and on 8), for checking some hardware issue if it exists. But on mac os x, as i already said, all is perfect, but on windows - randomly appers artifacts.
I record a video to illustrate my problem. http://www.youtube.com/watch?v=AwEog66vfFk&feature=youtu.be
Help me please! People in service told me that this is not a guarantee issue

I assume you have GPU-Z and other tools to look at gpu. the imac falls between notebooks and desktops when it comes to graphics. and it may be some programs just are not written for that graphic device? possibly?
I've been on Windows 8.1 mostly along with 8.0 and graphic drivers have been "bumpy road" at times and I was able to swap out and use different graphic cards on my PC - had me thinking I had an SSD related issue, then replaced memory (those were bad it turned out, and could have caused drivers and system errors).
Windows has memtest on the DVD and I have seen one or three people with real problems that did not show up until they did more tests, even though Mac OS was blindly oblivious to anything being wrong (it was, they upgraded RAM and SO-DIMM was not fully seated in one case, in another the RAM module had to be replaced).
Extended Tests using Apple Hardware Test is not conclusve and almost never ever when comes to finding gpu or memory 'errors.' There you are better with Windows test utility.

Windows 7 failing to install through bootcamp on iMac 27" late 2012

Hello.
I have recently received my brand new iMac 27" late 2012, and am trying to get it to install windows 7.
My machine is running 10.8.4 with a 3.4 GHz Intel Core i7, 16 GB DDR3 RAM and 500GB SSD drive.
I launched bootcamp and went through the usual bootcamp standard steps, and after it partitions and restarts, the windows installation stops at the point of choosing a partition.
To elaborate, after the windows setup starts, and I click install windows, it asks me to choose a partition. It happens to be Partition 4 BOOTCAMP (the one that bootcamp supposedly prepared for windows as an NTFS partition.
It does not recognize it as NTFS. I click on advanced options and click format, but it takes a split second and never really formats. The only thing that changes at this point is the name of the Partition (the word BOOTCAMP disappears from the partition name). Another thing I tried after reading full threads for 4 days straight is that I click delete to delete the partition, then on the now unallocated space partition, I click *New to reallocate/format the partition. It also takes no time to turn this into a partition supposedly ready for windows, but it never allows me to choose it and go next to start installation.
I have done this about 8 times now and I am starting to worry about damaging my SSD because of all the partitioning and unpartitioning.
Here are a list of things I have done:
1. made an ISO image of the windows 7 (64 bit of course) and ran that on a USB
2. downloaded the ISO image from the microsoft website and ran that on a USB
3. used an exernal optical drive to run the windows setup using the windows installation DVD instead of the USB ISO image.
I have made sure everything is fully updated, had a friend install windows on his macbookpro retina with an SSD running the same OSX and it worked just fine.
*a small note that may or may not be of importance is that when in the list of partitions in the windows installation I click on Load Driver, it does not detect any drivers although the USB with the drivers that BOOTCAMP created earlier on the Mac side is inserted in the machine and detectable.
What is it that I'm missing?

SOLVED IT!
after 5 full days of research and trial and error (only error and no progress) and after I had hit almost every wall there is, I thought of reviewing all the elements that make up the set up.
1. iMac
2. windows 7 installation (i had both optical drive for the dvd as well as an image on a USB)
3. usb stick with the drivers on it.
the iMac i trust.
windows i doubted. so i went ahead and checked the format of the usb on which i had the drivers. weirdly enough, both were exFat, which is created by windows - supposedly.
I decided to change the format of the USB with the drivers on it to FAT. re-downloaded the drivers on it and restarted... and it worked !
Although it does not make sense at all, but windows was reading from the image on one USB which was exFat, but was not reading the drivers on the other USB.
My guess is that the reason is the Mac OSX was reading the windows through the exFat and that was working, but the windows was not being able to read its own format on the other USB. Typical windows weirdness.
In any case, I hope if someone has the same kind of trouble they would be able to benefit from this post.
Also, maybe its worth noting in the instructions of BOOTCAMP.
Thanks for those who took the time to read it.

Black Screen iMac Late 2009 Fixed

This is just an FYI as when I had experienced my black screen on my Late 2009 Imac and read so MANY complaints
of people having the same issue I thought I would post my symptoms here. Due to the fact that my 3 year Apple care warranty
had run out I was faced with either bringing it to Apple and have them fix it or fix it myself. Taking it to Apple was out of the question
because of the amount of $$ they feel the need to charge for parts and labor.
I did my research and read many post of so many people having this issue.
Mine started one day whlile I was on my mac..my mac beeped and went black..So I replaced the memory..no biggie.
Then months later my screen would go black for no apparent reason. I would shut down, reset SMC & PRAM..It would come back for a little while
and just randomly go black. I thought maybe heat issue. So I cleaned vents & dust from fans etc.
Finally my Imac got to the point where the second I boot up..the screen would come on and immediatly go black.
I did the recommended things people had suggested.
I shined a flashlight on my mac LCD Panel while it was booted..I could faintly see my desktop folders ETC..
So I thought backlight board may need to be replaced. I purchased a new board, replaced..Not The Problem
I noticed that when booted and screen was black if I pressed the power button a couple of times the screen would come back
long enough for me to turn the brightness all the way down and still see the screen. At least this way I could run Extended Hardware
Test to see if it found any hardware issues. It found none and I ran the test 5 times. I thought this may have been power related
so I then purchased a brand new PSU from iFixit and that was not the problem.
I replaced all the lcd sync cables, temp cables, still not fixed.
Final resort. I purchased a LCD panel ( awesome seller on Ebay) used and in mint condition ( not a blemish). BINGO..
A new LCD fixed the problem. ( I did get silver tape & mylar to replace the stuff I tore off)
I have been running my Imac now for a couple weeks..non stop but I do shut down at night. I have had no issues now at all.
It feels just as nice & smooth and fast as it did from day 1.
What do I have left? A great Machine and some parts I took out as I replaced new ones and the old ones are probably good so I will have those
should my PSU or backlight goes bad. I may pick up a few more parts to have on hand and put away before it gets too difficult to find them.
I hope this helps anyone out there left with a late 2009 Imac..black screen..I am so relieved...

Hi-
Do you notice these smudge marks with the iMac off as well? If so, it is probably just some dirt or a fingerprint behind the glass on the front panel.
Yes, Apple or any authorized repair center can do this. 5 minutes tops. You could probably do it yourself (if out of warranty, which you are not) with a pair of suction cups to lift off the glass.
Again- you are under warranty, so I most certainly wouldn't do that.
Some users post being able to get a replacement iMac while their defective unit is in the shop, but those individuals have either had a history of having problems with their order, or were especially forceful in manner.
Don't count on being able to get one.

IMac 27in late 2012 Kernel Panic

Everytime I process photos on camera raw using my iMac, it hangs, white screens, then restarts on me. At first it I never had this issue but when it frequented into 3 panics per work day, I reformatted my iMac and installed only photoshop.
I checked on photoshop and turned off the OpenGL thinking maybe it was a RAM issue, but Claire (my iMac) still panics.
Please help. I need to get work done before I start losing money.

I have posted the same question in the adobe forum and their support has replied quickly saying:
That kernel panic refers to a bug in the OS code.
Applications cannot cause kernel panics, or machines to shutdown, freeze completely, or restart.
Only OS bugs, low level driver bugs, or hardware faults can do that.
please someone help me.

i upgraded my ram with 4 8gb corsair value system.
could that be the cause?
Very likely - their was a thread on here where someone on here was having the exact same problem with Corsair RAM. If I can find it I'll post a link.
If you still have your original RAM, take out the Corsair and put in the original chips. If the crashes stop - voila!
Macsales and Crucial are the often recommended places to buy from - they guarantee their modules will work.

IMac 27" late 2012 + new Apple TV 3: bluetooth disconnections

Hello,
I have an iMac 27" late 2012 working perfectly with wireless keyboard, magic mouse, and wireless trackpad until two days ago, when I purchased the Apple TV.
Since then I have continous disconnections whith Mavericks. Mouse, Keyboard and Pad lost connection and a few seconds later reconnects.
Just this post is impossibly to write, but with patiente....
Just note that when working with Apple TV in standby, with white led off, I have no problems like ever.
If I push any remote button power on Apple TV then automatically Mavericks starts in infinite loop to disconnect (the 3) and connect again.
Then put in stand by Apple TV and then all thing go fine again.
Note that when working with W7 with Bootcamp no errors, no disconnections, anything... All OK.
By this reason I think that the issue is located in OSX Mavericks, not related to the new ecosystem with Apple TV.
Obviously anything isn't going right with Apple TV, but still thinking that it is working OK.
Any idea? how can I check error logs in Mavericks?
The iMac is under Applecare covering, and the Apple TV is new, 2 days old.
Best regards.

Thanks for your fast reply!!!
I think that I have found what was shutting down Bluetooth on iMac.
I installed 2 or 3 weeks ago NotifyR on iMac to get notifies when received in iPhone.
I have opened console at iMac and I have seen that continously was looking for devices and when found Apple TV, with Bluetooth panel opened I saw that shutted down.
First of all I have put in OFF NotifyR. All has become normal. No disconnections of anything and no shutdown in general of Bluetooth.
I have sure at 99,99% that this was the problem. I will have it in quarantine...
I will remove NotifyR waiting for new capabilities of Yosemite!.
Thanks again. I hope that if someone have the same combination will help him.

IMac 27" (Late 2012) Freezing and Crashing

I purchased an ex-demo iMac 27" (Late 2012 - 3.4Ghz, 3TB Fusion Drive, Nvidia 680MX 2GB) that was upgraded to 32GB Ram last July.
Since I've recieved it it has intemittantly locked up, occasionally you get the your computers been restarted screen but mostly it just freezes completely. There's no pattern it can be at the login screen, on the desktop with no software running or when any software I use. There's no particular thing that seems to cause it.
I have run the Apple Hardware Test in Extended Mode Multiple Times and it reports no issues. I've run MemTest Continuosly for 24 hours and it reports no issue.
I've done clean installs of OSX multiple times (both Mavericks and Mountain Lion) and its had no effect. Even with a barebones OSX install it still freezes so I've ruled out software.
I've switched the RAM to rule out memory - still freezes.
I've used both WiFi and and Ethernet to rule out network - still freezes.
I've removed the Fusion Drive Logical Volume and installed OSX to the SSD and then to the HDD to rule out hard disks. This included zeroing the hard drive to ensure there was no bad sectors etc. This didn't make any difference.
I contacted Apple who told me to take it to an Apple Store or Apple Authorized Service Provider. I took it in to my local AASP they've told me they can't find anything wrong - everything works fine for them.
I'm wondering whether the issues are environmental. I've seen a few reports that "Dirty Power" can cause issues, has anyone had any similar experiences that have been solved by a UPS?
Failing that I'm at a loss at what to do. The iMac is unusable as it freezes every few hours.
Anyone have any ideas of what else I could try?
Thanks,
James

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to gather information about the state of your computer. That information goes nowhere unless you choose to share it on this page. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them.
Here's a summary of what you need to do: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a couple of minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in your browser, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter
exec sh
in the window and press return. You should then get a new line ending in a dollar sign.
Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know your password, or if you prefer not to enter it, just press return three times at the password prompt.
If you're not logged in as an administrator, you won't be prompted for your password. The test will still run. It just won't do anything that takes administrator privileges.
The test may take up to a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line "[Process completed]" to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report your results. No harm will be done.
8. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If it happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

IMac 27" late 2012 hard to sleep : start using on August it is easy to sleep but just few days ago ,it take half a minute to start sleep .

iMac 27" late 2012 hard to sleep :
- I start use this brand new iMac from August 2013 ,it is easy and quickly to sleep . Just few day ago it takes half a minute to sleep .
At same time the old iMac 20" 2007 got same problem .
Please help me to know what happen.
Thanks to our Apple Support Communities,
Garmin 108

Same problem here - only with a 2012 Macbook Air running 10.8.2
(very accurately described above )
After MBA sleeps and you try to wake it up, screen does not refresh properly and only refreshes where the current mouse cursor is.
If you close the lid, and then re-open the MBA then functions correctly.
I also have an issue where the MBA will suddenly crash while asleep and then will require a hard reset.
Not sure if related though.
I just reset smc/pram - will report back if this does not solve the issue.
If you don't hear from me again, then reseting solved it!

Vmware fusion 5.0.2 cannot connect to network on my brand new iMac '27 late 2012

Dear friends,
I have tried to install Windows 8 (x64bit) Pro., Windows XP, and CentOS 6.0 using vmware fusion 5.0.2 over my brand new iMac '27 late 2012. However, neither one can connect to the Internet. There was no problem with the same installation on my iMac 2011.
The network board recognized by Windows 8 is Intel(R) 82574L Gigabit Network Connection.
In the folder of vmware fusion's setting files on Mac OS, I found a file called Windows 8 x64.vmx, and
there is a line as follows.
ethernet0.virtualDev ="e1000e"
Any friend has the same problem or can give me some hints?
Thanks a lot!

IMac 27" late 2012 3TB hard drive bad blocks

Hi Guys,
I just received the new iMac 27" late 2012 with 3TB hard drive and as soon as I run Drive Genius version 3.2.2 I saw that the drive has 8 bad blocks.
I tried to deleted the logical volume and reinstall the OS X 10.8.2 and after a scan I got the same 8 bad blocks. I give it another try and erase the entire 3 TB volu except the recovery partition and installed Mountain Lion and after running another Drive Genius SCAN for almost 12 hours I got 8 bad blocks again.
Called Apple Support and they are clueless about what is going on as they are not even aware that the late 2012 iMac 27" is not even in stores yet.
I was told that as long as I do not have errors within the OS X I should not worry about as he HDD is fine. I do not believe it since from my experience when you have a bad block you also have a physical damage on you disk surface.
I called Apple Support again and I was told to go to Genius Bar and have them to replace the HDD to a unit not even a week old. I think that I am going to return the unit, maybe I got a lemon and the unit got dropped during the shipping process or who knows.
I hope that this thread will help other owners to have them to run a check disk or scan disk just to make sure that they do not have a bad hard drive on their new iMac late 2012.
Again I have nothing against to anyone as I just hope that someone from Apple will find this thread and try to prevent this from happening to a large scale.
Thank you.

Drive Genius will report bad blocks when none are present. It may even be responsible for disk corruption.

Get rid of Drive Genius. Do not install such junk on a Mac.

RAM Memory for iMac 27' (Late 2012)

Hi,
I have read a lot of discussions about what's the best option to upgrae the RAM for the iMac 27' (Late 2012), but I really don't know what should I buy in terms of compatibility.
Kingston ? Corsair? ,etc...
I pretend to remove the memory that's on my iMac (2x4GB) and install new ones 4X8GB=32GB, so, my question is, which brand should I buy, and also what about the voltage(1.3, 1.5) and latency (CL7, CL9, CL10, CL11...)?
Thank's

If you will go to either OWC (macsales.com) or Crucial, their sites will help you determine what you need.
http://eshop.macsales.com/shop/apple/memory/iMac
Use OWC's instructions to find your model identifyer. Their RAM has been tested and is guaranteed.
I would not recommend cheap brands or Value RAM.

How do you adjust the bass in the iMac 27" (late 2012) ?

How do you adjust the bass in the iMac 27" (late 2012)?
I am watching Youtube and the bass is very distrubing. Isn't there a way to adjust this on an iMac OSX?

AFAIK, you can't with the internal speakers. Contact Apple's Support, formerly Apple Express Lane, and see what they say.

Replacement screen for imac 27" late 2012

My new late 2012 27" imac has a scratch. Is it possible to replace the glass?

My cat pushed my late 2012 27 iMac off the desk and it fell on the floor. When I pulled it back up I gasped with horror. Although the LCD survived, the screen cover is cracked and the metal in the back bent a littlebit.
I have Apple care but obviously it woudn't cover the costs.
I took it to Apple and here is a quote for the repair: (I'm in the UK)

luckily I have accidental insurance, therefore the cat is still alive.
