Mid 2011 iMac Graphics v 2012 iMac

Ive got a mid 2011 iMac with the Radeon HD 6970m graphics.
I was thinking about getting of the new iMacs, and compared the graphics card in my current iMac to the new ones at http://www.videocardbenchmark.net/
This seems to show that my current 6970M is over twice as fast as the Geforce ones in the new systems, am I reading this right?

The iMac's GPU is damaged. GPU problems appear and disappear, so it's normal that sometimes the iMac works correctly.
Now, I recommend you to take the iMac to an Apple Store or reseller to get your GPU replaced. The GPU isn't expensive (about $99, depending on the GPU), so it's better to take it instead of trying to do it yourself. I haven't found the steps to replace the GPU on the Mid 2011 iMac

21,5 (mid-2011 2,5 GHz i5) iMac screen noise (whistle) : What to do?

Hello,
I saw that nearly all the 2009 and 2010 iMacs have the screen noise problem (they whistle) : https://discussions.apple.com/thread/2209558?start=0&tstart=0
I bought my iMac two days ago (it is one with Snow Leopard pre installed), and I also have this issue : my iMac whistles.
Does anyone else have this same problem on a mid-2011 iMac ? Did Apple fix this problem with the iMacs where Lion is pre installed ?
Otherwise my iMac is perfect. What should I do? Shall I keep it or bring it to my local Apple Premium Reseller ? Can I expect a refund ?
Thanks for helping.

I recently bought my iMac. Have the same problem. Horrible. I am struggling with Apple care right now. They refused to believe there is a problem. I don't know what to do either now. If they can fix it, I am looking for a refund.

Macbook pro mid-2011, has graphic issue?

Hi, I am using macbook pro 2.7ghz,i7,4gb,hd graphic 3000 which i just purchased in the mid-2011 to replace my old macbook.
Everything seems fine until I reinstall the sims 3 to my new macbook pro. The video's works fine, but when i entered the create household,
it shows the person's eyes and thumbails were not clear. The details setting of the game, has been set all to low which is the default setting. I have tried to increase some setting to medium or high, but it have not make any changes. Any solution?

it was working fine with my old macbook, and my sister who is using macbook pro 15" also works fine. I also installed the sims medieval, but the same issue occurs. i have the latest update for macbook pro sofware and also the sims.

Usb pin bend in macbook air(mid 2011,bought in april 2012) demands a complete replacement of the logic board which costs around $500.Is it justified?

I had recently purchased a macbook air mid 2011 in india (surat) and to my surprise two out of four pins of the usb slot on the right side got bent while trying to insert a usb pendrive.I was shocked when the store said that it was a physical damage and it will not be considered in the warranty(apple care protection plan) and i would have to pay around $500 to replace the logic board with the new one since the usb port was directly mounted on it.
I have been using the usb port since the time it had came to market and i know how to plug in a usb drive.There is no case of inserting the usb pendrive inverted as the structure of the usb port itself explains it.
I have already read the discussions on such an issue and many people have got the logic board repaired by the company.
But i will be thankful to the person who has gone through the same situation and put forward his experience about how to get a "fast response repair from apple" in response to this discussion.

Applecare was no help at all. I called and did the complaint. They confirmed that it is registered to me and everything but essetially told me that they cant give me answers as to what is taking so long. They knew a repair was in progress but wanted to set me up with an appointment at an apple store? (the nearest Apple retail store is Billings which is 240 miles away, or about 4 hours). i tell them its at the repair place and they go on to tell me they can send me a box to mail it in and have it reapir by them.. They are trying to shift the blame to the AASP and his rep. But he said he has been trying with very few answers from Apple as well

HT204291 I can connect to the apple TV but I am not getting display only sound with my IMAC mid 2011 and MAC Air 2012 both with Mountain Lion OS

I just upgraded to Mountain Lion after purchasing Apple TV yesterday from Best Buy.
I have signed in on the same wi-fi network (comcast 30mbps)
I was able to see photos from my wifes Iphone but not my IMac or Mac Air
Both computers connect but I am only getting audio.
I updated software on Apple TV
I shut everything down and reset my router. My Mac Air 13" 2012 was able to see the desk top but not anything that I was doing and then it disconnected.
I also tested the internet speed on the Apple TV but it just told me it was finished. (no results)

WEP as a security measure is laughable nowadays. Even a kindergarten kid with a netbook can crack the password in a few minutes. Try using WPA2 if available on the device. And the Macs will be quite happy connecting with that protocol.

Cannot upgrade Thunderbolt firmware on mid-2011 iMac

Hi - I'm having problems updating the Thunderbolt firmware on my mid-2011 iMac (21.5").
Can anyone point me to the proper location for this firmware download? I've found several on the site, but none seem to work for me, due to a variety of OS incompatibilities.
For the curious, here's what my system says:
Hardware Overview:
Model Name: iMac
Model Identifier: iMac12,1
Processor Name: Intel Core i5
Processor Speed: 2.7 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 12 GB
Boot ROM Version: IM121.0047.B1F
SMC Version (system): 1.71f22
Thunderbolt Bus:
Vendor Name: Apple Inc.
Device Name: iMac
UID: 0x0001000A15928E80
Route String: 0
Firmware Version: d.16 (Eng 1)
Domain UUID: 78CF7309-6B81-CC54-A320-6D5B13722358
Port:
Status: No device connected
Link Status: 0x7
Speed: Up to 10 Gb/s x2
Receptacle: 1
Port Micro Firmware Version: 1.2.1
And here are the error messages from a variety of firmware update locations:
Thunderbolt Firmware Update v1.2
First error: The package was signed with a certificate that has expired (c'mon Apple!)... Do you want to continue with the installation anyway? (yes!)
Second error: Alert: This software is not supported on your system. (any reason why? OS, old other firmware, what?)
I've tried the tricks of PRAM and SMC resets, moved the com.apple.SoftwareUpdate.plist to the desktop and rebooted, etc., etc., but nothing seems to work.
The issue driving this exploration is that the Thunderbolt port appears to be dead - won't support Target Desktop Mode or the Thunderbolt Gigabit Ethernet adapter.
Thanks in advance for any help!

From that very page, it appears that this model does support Target Display Mode - please see the bold text below.
Am I reading it incorrectly?
Thanks for your help here - it's good to have more than 1 set of eyes looking at this!

How do I use my mid 2010 iMac as display with mid 2011 macbook pro?

I have a mid 2010 iMac and I want to use it as a display for my mid 2011 macbook pro.
The iMac has a mini display port and the macbook has a thunderbolt port.
Does anyone know if this is possible and what I need to make it possible?
Cheers!
-Sean

If the iMac is a 21-inch model, you need to use a product such as ScreenRecycler over a network.
If the iMac is a 27-inch model, click here and follow the instructions.

If it was previously working then try a smc and pram reset.
If that doesn't fix it then see if vlc can handle the video.

I have a mid 2011 27 inch iMac and a late 2012 mac mini. I am using the 27 inch iMac as the display for the mac mini. I was trying to use bootcamp on the mini but after I started downloading windows I can't get it to display on the iMac.

Hi there,
The simplest way is to drag it across wirelessly using the 'Airdrop' application once both computers are near one another. 'Airdrop' can be found near the top, on the left hand side menu, within 'Finder'.

HT1338 Software Update is not finding latest release (April 3) of Java 2012 001 Update for Mac OS X Lion 10.7.3 on iMac mid-2007 that downloaded automatically on iMac mid-2011

Software Update is not finding latest release (April 3) of Java 2012 001 Update on my iMac mid-2007, but it downloaded it automatically on my iMac mid-2011 yesterday. Both are running Mac OS X Lion 10.7.3. When I try to download the update manually from Apple on my older iMac, it downloads okay, but when I try to open the dmg file, I get a warning message saying that opening this update may make your computer LESS secure. Do you want to proceed? (I did not).
Why would Software Update find this update and install it automatically on one iMac and not the other, if they are both running the same version of Mac OS X Lion? I checked the installed software list on my old iMac and the Java update does not appear there. Why would this update make my old iMac less secure?

Recall that Java is not installed as part of Lion.
You have to install it (and are asked if you want to) when you first try to run some java stuff.
Is it possible that the iMac 2007 does not have Java yet?
Try this: open Terminal (from Utilities) and type java -version (exactly like that, with the space before the hyphen).
What do you get?
Consistent with this theory is that the dmg thing gave you the warning - installing java might make your machine less secure because java is a means for bad guys to try to do bad things to your computer.

Graphics card issue iMac 21.5" mid 2011

Hello,
I have a 21.5" mid 2011 iMac with windows 7 64bit installed and when I open DxDiag it says to me that my graphics card has 221MB of dedicated memory instead of 512. Can this problem negatively affect the computer's performance (for example while playing games)? How do I fix this?
My graphics card is the ATI Radeon 6750m.
Thank you very much for helping.

Anyone can help?

Is there an Update Driver for my Graphics card, AMD Radeon HD 6970M 2048 MB , in a 27inch mid 2011 iMac? thank you!

Is there an Update Driver for my Graphics card, AMD Radeon HD 6970M 2048 MB , in a 27inch mid 2011 iMac? thank you!

Upgrade Mid 2011 iMac 27'' Graphics Card?

Hello all, and thanks in advance. I have a mid 2011 iMac 27'' and for work, I do a lot of film and effects editing. I have currently ordered more RAM but my newly updated programs require an Nvidia card with CUDA drivers for rendering. Is it possible to upgrade the graphics card in my mid 2011 iMac to a newer, faster card?

Thanks for the quick response. I understand they are part of the logic board, and it appears that they weren't designed to be easily accessible, but is it even possible? With some risky work, could it be possible to place a new card in? Or is it designed so other cards won't even fit?

Why my iMac says that it is from mid 2011, when i bought it in 2012?

i bought my imac in miami last month and i cant understand why it is mid 2011 model.
i know that there is a late 2011 model, i just cant undestand it!

MId-2011 is the last update to the iMac platform. That's how Apple refers to it's systems. Before that it was the mid-2010 iMac and before that late 2009. You can see the nomenclature and specs at http://support.apple.com/specs/#imac
The late 2011 iMac is, as I recall, for educational institutions with a Core I3 chip. You can't buy that from the online store.

Mid 2011 imac graphics card

Sometimes getting green vertical lines at start up and then will not boot up. Restart a few times and then it finally functions properly for a while. Not sure if there is a user friendly fix or not.
Thanks
