Ivy-Bridge for Mid 2011 21.5" iMac
Hi everyone, My Mid 2011 21.5" imac will not boot anymore did all the necessary steps still no go. My iMac is out of warranty. Is it possible to exchange the Processor from my i7 2600s to NEW " i7 3770s " To my understanding that the TDW of 65w are identical. Need your advice on this. Thank You
No startup chimes? No screen? do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.
If still nothing, could be the power supply.

I got a new Apple TV for Christmas, I read tha the OS X Mountain Lion supported AirPlay with the Apple TV, so I paid for the OS upgrade. After the upgrade I found out that AirPlay is not supported on iMac's older than mid 2011. This ***** because this was the only reasion I needed the upgrade, It should have been more clearly posted that the features of the new OS were only supported on specific machines!
Short of buying a new iMac is there a way to use Airport Mirroring from my iMac to the TV ?
What other Mountain Lion features don't work on a late 2009 iMac ?First, if you would have visted http://www.apple.com/osx/specs/ you would have seen there is a VERY LARGE and IN BOLD section that covers what functions of 10.8 are limited to what macs. Second "needed the upgrade"... spare me.
To your, "work around" question a lot of people report a third party app named "air parrot" as pretty reliable. You're welcome to try your luck with that. -
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 with a thunderbolt cable. 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'.

Hi I am trying to connect my mba mid 2011 with an imac 27" 2011 with target display mode tdm. When I am using a thunderbolt cable nothing will work. When I use a minidisplay cable, both screens turn blue but eventually nothing happens. What is the problem
Your answer is likely in Target Display Mode: Frequently Asked Questions (FAQ) - Apple Support If you are familiar with this document, please re-read it and I suspect you may find something you either missed or are doing incorrectly.

Which is the best hdd for mid 2011 imac
I am bit confused to choose from these 1TB 3.5" HDD
1. Seagate
2. WD Green
3. WD Black
I mainly use this iMac (21.5", Mid 2011) for Photoshop with large files from 800MB to 3GB. Some video editing etc.
Also I don't know the WD Black is compatible with the power supply or not as the HDD require more power than other HDDs.
Please suggest.APC is a fine brand and probably the most recommended on these forums. One major error I see you made is to install PowerShute, it's simply not compatible with OS X and should not be installed. You should contact APC Tech Support for instructions on how to correctly uninstall it. I think once you do if your KP's are related they will go away. You should handle this first, don't just trash the software, that will not get rid of it. You need to follow APC's uninstall instructions, I know because I found out the hard way.
If all that is wrong is the battery has died then simply get a replacment battery. You can buy replacements from APC or from a battery distributor, I've even seen them on EBay. They're about like car batteries, when they go dead you replace it. -
How do I update firmware for mid 2011 iMac running Yosemite?
I tried the link in the Apple support pages, but it told me I need Lion to install it. I bought the computer used. It came with Mavericks and I updated to Yosemite. I don't have Lion or any way (or desire to) install it.
There is no update for the mid-2011 iMac firmware that will fix the fans running at high speed.
Only the OEM (original equipment manufacturer) Apple hard drives had the proprietary firmware designed to properly monitor the hard drive temperature.
So you have several possible solutions:
1. If the computer was sold to you with a warranty, rather than "AS IS", my first choice would be to force the seller to restore the computer to the condition it was represented to be in when you purchased it, with an OEM Apple 500GB drive that does not cause the fan problem. If they cannot or will not correct the problem, make them take it back and refund your money. Consumer advocates such as the Better Business Bureau can help you prepare a formal complaint against the seller, and perhaps lead to a successful resolution through arbitration, without hiring an attorney and filing a lawsuit.
2. If you bought the computer "AS IS", you'll have to attempt to repair the problem yourself:
A) Locate an exact replacement for the original OEM Apple hard drive with the proper firmware and install it on your own;
B) Purchase a 'compatibility kit'. OtherWorldComputing www.macsales.com reverse-engineered a solution to the problem and sells a short cable with an external temperature sensor for the hard drive that can be used successfully with non-OEM drives. http://eshop.macsales.com/item/OWC/DIDIMACHDD11/
They also sell the sensor cable with a toolkit that can be used to disassemble and install the cable. http://eshop.macsales.com/item/OWC/DIYIMACHDD11/
C) Try the fan control program mentioned in earlier replies. -
SSD install in mid-2011 21.5" iMac
Hello, community. Let me preface this by saying I consider myself to be a very technically inclined individual as far as computers, etc. go, so, don't be afraid to pass on the lamen's terms, and such. Anyways, with that said, I have never been inside an iMac. I have only delt with the insides of PC's and some Mac Pros, so I have a fair amount of knowledge when it comes to parts, etc. At this point, my primary computer is this 2011, 21.5" iMac. I upgraded the ram a year or so ago and now I would like to install an SSD. In the past when building PCs, and upgrading others, I have had exceptional luck with OCZ Vertex SSDs and Kingston Hyper X's. With that said, I have only worked with SSDs inside the Windows environment. I have never done anything with OS X, as far as they are concerned.
So, with all that said, I do know the following:
I will be removing my optical drive for the SSD
I will be keeping my stock 500GB HDD inside the machine (if I can use it)
Which brings up my first question:
Can I use both my SSD and stock HDD within OS X? (SSD as a boot volume, per se, and the HDD for storage?)
And will I need any special brackets, cables, etc?
As I said, I have no experience with iMac internals, so the whole process will be new to me. however, I did manage to find a pretty detailed teardown/rebuild video for my particular model. I just need some info on the software side of things, really.
Thanks!First, you need to prep the SSD:
Drive Partition and Format
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button or set for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
How to use an SSD with your HDD
If you are going to use an SSD as a boot drive together with your existing HDD as the "data" drive, here's what you can do.
After installing the SSD you will need to partition and format the SSD using Disk Utility. Then, install OS X on the SSD. After OS X has been installed boot from the SSD. Use Startup Disk preferences to set the SSD as the startup volume.
Open Users & Groups preferences. Click on the lock icon and authenticate. CTRL- or RIGHT-click on your user account listing in the sidebar and select Advanced Options from the context menu.
You will see a field labeled "Home dir:" At the right end you will see a Change button. Click on it. In the file dialog locate the Home folder now located on the HDD (HDD/Users/account_name/.) Select the folder, click on Open button. Restart the computer as directed.
When the computer boots up it will now be using the Home folder located on the HDD.
Another more technical method involving the Terminal and aliases is discussed in depth here: Using OS X with an SSD plus HDD setup - Matt Gemmell. This is my preferred approach because I can select which of the Home's folders I want on the HDD and which I don't want. For example, I like to keep the Documents and Library folders on the SSD because I access their content frequently.
Be sure you retain the fully bootable system on your HDD in case you ever need it. -
Thunderbolt update for mid-2011 MacBook Air causes slowdowns and flickering?
So I've experienced not one problem since getting my mid-2011 MacBook Air. After installing the Thunderbolt update that was pushed through Software Update the other day, I've noticed that when I go into Mission Control or App Expose it's more sluggish than it used to be.
Additionally, I saw my screen flicker several times - I have never seen this before.
Has anyone experienced similar problems since installing this update the other day when it came out? I'm most concerned about the sluggishness of the screens.
Thanks,
BJCI never installed it, it's popped up each time I've checked -- but today it wasn't offered in Software Update. Odd.

Mid 2011 21.5" iMac restarts for no apparent reason
just started a month ago and my machine is only 4 1/2 months old. It restarts for no apparent reason no matter what app I'm in. The apple techs can't find a reason for it and just say 'clean install'. Well, it's had 4 clean installs in two weeks with no help in sight. I know others have this problem and I wish I knew who at Apple I could contact to see about a replacement instead of being jerked around by the apple store.
After it restarts, does it present a dialog box like this:
Next time they recommend "clean install" please have them show you an Apple Knowledge Base document that defines it, because without knowing what it is makes it difficult to know what they did. -
I have several new mid-2011 21.5" imacs that kernel panic
The are running fully updated OS X 10.6.8, booting to a 64bit kernel. All the available firmware updates for the graphics card and bluetooth have been done. If I boot them into Safe Mode or into 32bit kernel mode, they do not panic. That being said, I know it is possible it is a piece of software that could be causing the issue, but I wanted the crash log posted and looked at anyway - incase I am wrong.

Mid-2011 21.5" iMac kernel panic
I have run AHT and ASD and neither have found a hardware issue. The machine is has no added or third party RAM.
The machine randomly kernel panics, typically before your able to log in. I have pasted the last two kernel logs below. Any help would be great.

Mid 2011 21.5" iMac freezing constantly
As of lately, my iMac has been constantly freezing. At first I had a problem with bad RAM causing kernel panics after I installed 16GB of Patriot Viper memory, I thought it was the Patriot Memory because everything was fine until I installed that. I figured it was because it was 1600 MHz and my iMac is rated for 1333 MHz. Anyways, I ran the Apple hardware test to find that the original RAM was the suspect but just to be safe, I replaced ALL RAM with Corsair RAM (8GB x 4 for a total 32GB). Now, on to my new problem at hand. My iMac is constantly freezing, everything is up to date, I have ran Disk Utility with no abnormal results, reset PRAM/VRAM, reset SMC, I also downloaded multiple third party apps to check my disks etc, and it seemed it was running hot so I downloaded iMac Fan Control and set the temperatures as follows:
Lower Temp Threshold: 46C
Upper Temp Threshold: 85C
Slowest CPU Fan Speed: 1200

booted in Safe Mode and so far no freezing. Any ideas on what to do?Please read this whole message carefully, especially the warnings, before doing anything.
1. I can only guess which of the modifications you've made to your system is causing the problem. The changes suggested here should be considered provisional; they may not help, or they may remove functionality that you find useful. If a third-party system modification that you want to keep is at fault, refer to its developer for support.
2. WARNING: Back up all data now if you haven’t already done so. Before proceeding, you must be sure you can restore your system to its present state, even if it becomes unbootable. If you’re not sure you can do that, STOP — DON’T CHANGE ANYTHING.
If you don't like the results of the procedure suggested below, restore from your backup.
I will not be responsible for the consequences, and I will not be able to help, if you ignore this warning.
3. You should either remove or update the following system modification(s), if an update is available from the developer:
[Not applicable]
and definitely remove at least the following:
† FreeMemory
† TechTool Pro
4. Whatever you remove must be removed completely, and (unless otherwise specified in this message) the only way to do that is to use the uninstallation tool, if any, provided by the third-party developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job. I can't be more specific, because I don't install such things myself. Please do your own research.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button.
Again, please don't ask me to do this research for you. You can do it better than I can, because I don't use the product and I may not even know what it is.
You will generally have to reboot after uninstalling a system modification. Until you do that, the uninstallation may have no effect, or unpredictable effects.
5. If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
WARNING: Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.
6. I recommend that you never reinstall the modifications marked with a dagger (†) above, if any. If your problem is resolved after uninstalling all the above modifications and rebooting, but you still want to use some of those not marked with a dagger, you can experiment with putting them back, one at a time, testing carefully after each step. Keep in mind that system modifications may be incompatible with each other or with future OS X updates, so it may not be clear which one is at fault.
7. If you still have problems after making the suggested changes and rebooting, post again. Remember: if you don’t like the results of this procedure, you can undo it by restoring from the last backup you made before you started.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Enter the following command in the Terminal window in the same way as before (triple-click, copy, and paste):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2>&-
This time you'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
Boot into Recovery. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open. In that window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
▹ Restart
from the menu bar.
Launch the Font Book application and validate all fonts. You must select the fonts in order to validate them. See the built-in help and this support article for instructions. If Font Book finds any issues, resolve them.
From the application's menu bar, select
File ▹ Restore Standard Fonts...
You'll be prompted to confirm, and then to enter your administrator login password.
Boot in safe mode to rebuild the font caches. Boot again as usual and test.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. In that case, ask for instructions.
Also note that if you deactivate or remove any built-in fonts, for instance by using a third-party font manager, the system may become unstable. -
Is there anyway to upgrade the processor and/or the graphics card on the mid 2011 21.5" iMac?
I am a gamer and I am always looking for my games to run as smooth as possible. I feel that if I step it up a notch it would do much good for my computers performance with gaming. I could be wrong.
Specs:
Processor: 2.5 GHz Intel Core i5 Quad core
Memory: 8GB 1333 MHz DDR3
Graphics: AMD Radeon HD 6750M 512 MB
Is there anything I can upgrade that will improve my computers performance on the games I play?
ThanksRRFS,
I couldn't agree with you more.
iMacs are all in one computers with very little user upgradability.
iMacs, in particular, are not tinkering computers. The are not PC towers, at all!
To many things meticulously crammed into avery confined enclosure.
iMacs only come in pre-defined configurations from Apple or you can, iniitially, custom order an iMac with whatever available components Apple presents as custom upgrade options.
Plus I doubt your parents would allow you to pry into a two month old Mac and void the one year and subsequent upgrade of the AppleCare warranty.
And if you tried and screwed something up in the take down/re-assembly process, you not only be screwed with AppleCare service, youor your parents would have to pay Apple's very expensive repair services out of pocket.
By the way, if your parents or you do know, you can extend out AppleCare for another two years after the initial warranty period. I would strongly advise getting the extended warranty plan when the time comes.
Sorry for the bad news. -
EFI Update available for mid 2011 Mac Mini
New update available today, check Software Update for the download and follow instructions to update correctly.
And be smart. Backup first and install ONLY the EFI update. Do any other updates separately. Most problems with EFI updates seem to come when people install other updates at the same time. One at a time to be safe, as an EFI update can turn your mini into a brick if it encounters problems.

What is the best 2 TB hard drive to put in a Mid 2011 21.5" iMac ?
Looking to Upgrade my hard drive to 2 tb what is the best hard drive to use?
For internal, you can't go wrong with the Hitachi Travelstar. They work very well with the MacBook Pro and right now you can get 300 GB of 7200 RPM for less than 75 dollars at Newegg. You could try that and see if you really need an external given the type of music you're working with.
If you decide to get an external, I would steer away from all-purpose drives and get one designed for audio, like the Glyph drives. Along the Apogee Duet simplicity lines, they're designed for music production and they just work. Most of them come with carrying cases. Just plug the Glyph into your MacBook Pro, plug the Duet into the Glyph, and that's it.
