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

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

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?

THank you very much, I I have a ton of Adobe programs on my mac and i think a Cuda driver update was installed with it, it just popped up the other day in my system settings and is asking to upgrade my graphics card, but i don't have the same card as this update... so i thought i would double check! thank you again.

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?

Where did 30GB of unused space on my SSD main drive go? I have a mid 2011 iMac that until yesterday had just 54GB of space occupied on the primary drive. I imported 45 minutes of video from an SD card. Could that have used up the space?

I added an SSD to my 27" 2011 iMac. Although Sahidus is absolutely correct, it is much easier to add an SSD replacing the optical drive, it wasn't that bad to add it using an entirely seperate cable using SATA-III. To me it is worth the extra hassle to install a SATA-III SSD. This is where you are going to get maximum performance.
Although it appears complicated, if you go slow, the procedure to install an SSD drive isn't too bad. It takes at most 3 hours, as long as you are prepared and have all the parts and tools.

This describes how I did it. Now I get awesome data performance from my iMac!
I think the 21.5" may be more difficult to find where to place the SSD. But im sure it is possible. Just be creative.

Maximum RAM upgrade possible on a mid 2011 iMac 27"

Can I upgrade my mid 2011 Imac 27" to 32 gb of RAM. Apple handbook says only possible to upgrade to 16gm (4x 4gb cards). Has anyone upgraded a 2011 Imac 27" to 32gb of RAM?

Yes, both OWC, http://www.macsales.com and Crucial, http://www.crucial.com offer 32 GB ram kits that are guaranteed to work...to do that you would be best to not buy from sources that are not Mac specialists and who guarantee their ram to work.

Mid 2011 iMac continuity issues!

I have recently upgraded to OS X Yosemite on my Mid 2011 iMac, but continuity doesn't seem to work on it. Is my iMac to old?

I did install Yosemite in my 27" iMac (Mid 2011) last Friday and after 6 hours of use I got display issues. After the iMac comes back from sleep I get pixelated blocks in random areas that stay on background until open a new app window. Two days ago my computer frozen and got pixelated blocks all over the screen. After restart got the graphics problem box and asked me to report it which I did. I restored Mavericks from my time machine and everything was working fine again. Then yesterday afternoon did a Yosemite clean install in my iMac and this morning got the same display issues and computer completely frozen. I restored Mavericks AGAIN and everything is working fine so far!!! I'm gonna stay with Mavericks until Apple release a fix for my issue.

I have a 27in mid 2011 iMac and a 2006 mac mini

i have a 27in mid 2011 iMac and i have been given a 2006 mac mini i have no screen to see whats going on on the mini and there is no os onboard how do i get OS X on to the mini so i can get to use this with a tv with hdmi i have the mini dvi to vga connector and a vga to hdmi lead into a samsung 32in led tv, tv keeps saying not connected???

- You said "Apple dvi to via converter with a via to hdmi cable . What is a "via"? I think you mean VGA.
Just what VGA to HDMI cable to you have? VGA is analogue while HDMI is digital. The Mini DVi out is both analogue and digital (DVI-AD). You would need a converter to convert the analogue VGA to digital.
- Yes, when you boot up you should get a chime if the Mac is functional. The chime The sound indicates that diagnostic tests run immediately at startup have found no hardware or fundamental software problems.[1]

Thus it appears the Mini also has a hardware problem.
Make an appointment at the Genius Bar of an Apple store. It is free.

Nevermind, I got it working.
I ended up extracting the new vob within MPEG Streamclip, which gave me an m2v and an aiff audio. I multiplexed those two back together in FFMpegX which gave me a complete VIDEO_TS folder with BUP and IFO files I needed.

Is there a way to run a external ssd with my mid 2011 iMac hdd in a raid configuration and basically have a fusion drive

is there a way to run a external ssd with my mid 2011 iMac hdd in a raid configuration and basically have a fusion drive

A Fusion Drive is not a RAID; it's a CoreStorage logical volume group. While it's technically possible to do as you suggest, there would be little or no benefit from it.

The dropdown menu from the Creative Cloud icon on the menu bar keeps giving me the following message: "Download Error" I quit and restarted the creative cloud app to no avail. Running Mavericks on a mid 2011 iMac.

Click on Finder and then hold Command + Shift + G keys on your keypad
It will open Go to folder window, type exactly ~/Library and click on Go
Make sure to open ~/Library not /Library ( there will be two Library folders )

Then launch Creative Could and check.

How do I restore my 27" mid-2011 iMac EXACTLY the way it was after hard disk replacement?

Hi all.
Recently received an email from Apple saying that the 1TB Seagate hard drive in my 27" mid-2011 iMac is apt to fail anytime. Apparently they used some bad hard drives in the mid-2011 27" iMacs which are problematic so they're offering me a free replacement to a brand new hard drive. I'll be sending in my iMac for the replacement sometime in the next few days.
In preparation for it, I've backed up my entire system using Time Machine into an external harddrive. The backup is up to date & includes all system files. I've also made a Lion install disk on an 8GB USB flash/pen drive using Carbon Copy Cloner.
My question is: When I get my iMac back after the hard disk replacement, will I be able to restore my iMac to EXACTLY the way it was before the replacement using the Time Machine backup & the Lion install disk that I've prepared? When I mean EXACTLY, I do mean EXACTLY, e.g I don't have to re-install all the programs I have, my settings for the programs I have will stay intact, everything is where it should be etc...i.e EXACTLY the way my iMac is right now.
If yes, how do I do it? I've read Pondini's guide: http://pondini.org/TM/14.html
However it is less than clear on certain points, e.g in my case, which one do I have to use to restore my system to the way it was...the Time Machine backups I have on the external HDD or the Lion install disk that I made using Carbon Copy Cloner? And how do I go about doing the restore?
I'd appreciate any & all help given. Thanks in advance!

baltwo: Thanks for your input! I didn't think of wiping the old HDD before sending it in for the replacement..all those sensitive user data! One question: What's a FWHD?
Already answered. Just note that FW is much faster than USB. See http://help.bombich.com/kb/troubleshooting/how-long-should-the-clone-or-backup-t ake for details.
I already have CCC installed so I'll probably try it out. Are the steps outline here the one that I should do to restore the CCC clone when I get my Mac with the new HDD back? See: http://help.bombich.com/kb/overview/restoring-data-from-your-backup#full_volume_ restore
Yes.
Another question: while I'm booted on the backup/clone, and just after I've wiped the old HDD, how do I reinstall the OS to create a generic user account? Will I have to use a Lion install USB disk?
No. IIRC (if I remember correctly), you can either use a saved Lion installer (hopefully it exists on your backup/clone) or use the Recovery HD. If you have the USB stick w/Lion installer on it, use that.

Mid-2011 iMac won't boot Win 8.1 (BC) w/ ACD 30 attached

I have a 27" mid-2011 iMac Core i7 with two external displays, an ACD 30" and a 20" HP. I spent a great deal of time watching Win 8.1 in a reboot loop after install (Apple Drivers installed fine), sometimes with vertical lines down the ACD 30 (nothing on the HP). (I didnt expect Win to notice the more than one DisplayPort screen.) Finally I disconnected the displays and I booted into 8.1 fine.
IS this a thing? Others share this experience?
Thats not the end of my Boot Camp woes, but that's all tied to this issue.

Can you provide details on how each these displays are connected?
From iMac (27-inch, Mid 2011) - Technical Specifications, you have two TB ports, which can support DP connections.

Re-Installing Snow Leopard on a mid 2011 iMac

I have accidentally wiped the hard drive of a mid 2011 imac 27" there was no install DVD provided for this machine and a retail Snow Leopard disk will not boot, apparently I need 10.6.8 and the retail disk is only 10.6.3 is there any solution to this dilemma?

The machines (we have more then one) all came with SL but no install disks. When I boot with cmd-R it comes up with a globe icon and message - apple.com/support - 6002F. I am now convinced that these machines were so close to the Lion release and were probably intended for Lion but were shipped with SL. I have now tried everthing including Lion install from USB recovery stick created an another SL to Lion machine and this works to the point where after downloading all 3GB of Lion it just goes back to the beginning again! I tried 3 times - good thing we have fast broadband and it failed every time! I then tried restoring a SL and even a Lion clone from another similar Mac but kernel panic every time, tomorrow I will try the retail "Lion on USB" option but it looks like its off for repair as far as this MAC is concerned.

How do I migrate data from my 2003 iMac to my mid-2011 iMac?

Hi All,
I have a 2003 iMac and I want to migrate the iTunes, iPhoto, etc DBs to my new mid-2011 iMac. The 2003 iMac is the last one before they switched to the intel chip. It's Mac OS is version 10.5.4. That's as late as I can get it as they quit supporting the old chip after that.
I found a vid on mac-to-mac file migration online. It said to connect the two computers via firewire cable (done), start the new computer (done), start the old computer while holding down the T-key (done), and the old computer's hard drive will show up on the new computer finder window (did happen). Then it says to start Migration Assistant on the new computer (done), and follow directions. That's where I run into a problem. The Migration Assistant says "Looking for other computers" and it never finds the old iMac even though the old iMac's hard drive is visible in the new iMac's finder window. Note that I can click down through directories on the old iMac in the new iMac's finder window.
Any suggestions you can offer would be greatly appreciated.
Thanks much!

Your old machine may too old for Migration Assistant to work. In that case your best bet is to set up the old machine in Target Disk Mode and then drag and drop your files to the new machine. You should only migrate data files, if you have applications on the old machine these should be manually installed on the new machine. If any of the old machine's apps are PPC (Power PC) based these will not run in Lion and will need to be upgraded or replaced prior to installing on the new machine. You can check what apps are PPC based by opening System Profiler (Applications - Utilities - System Profiler), click Applications on the left and then look in the Kind column. Applications that will run in Lion OK are Intel & Universal apps.
