IMac 21,5 late 2012, Fusion drive noise

I have the new 21,5 iMac with Fusion drive 1 TB, 16 GB RAM. I have hoped to hear nothing from the Mac. But I always have a low, but permanent noise which I suppose to come from the fan oder the hard drive.
Can anyone comment on his/her experiences with fusion drive in a new 21,5 iMac and the noise coming from that?
Thx
Holger

Hi,
let me share my experience:
I had a similar problem with my new 27'' late 2012 iMac with 1 TB fusion drive and 16GB RAM. There was a consistent noise as if the HD was permanently working. All functions and HD checks were normal. The HD started even buzzing when scrolling a website - sounded like a trapped fly.
I brought it back and they exchanged the HD: Better, but still not to the standard expected from this high-end machine. I brought it back a second time, thinking I was overly sensitive, asked them to check again and was even willing to upgrade to a SSD if the technician would call this "normal".
They exchanged the HD for the 2nd time, and also the LCD display and:
it is gone - completely gone !
And it appears overall performance of the machine is faster than before.
Hope it helps, if someone has similar doubts as I had.
Cheers
JK

IMac (27-inch, Late 2012) i want to put ssd blade

iMac (27-inch, Late 2012)
3,2 GHz Intel Core i5
24 GB 1333 MHz DDR3
Hello I want to put SSD blade in my iMAC 27 , maybe someone of you know where to find the ssd blade finishing dig up the entire Internet , but do not understand , really that ssd . Suitable for MacBook Pro and MacBook in 2013 and also 2012? I planned put 512GB max 256GB Help me !!

The SSD blade drive is a very thin SSD that looks a lot like a memory module. It connects to a PCie slot instead of an HD sata port.
According to EveryMacs overview:
For storage upgrades, if the 21.5-Inch "Late 2012" iMac models were not configured with an SSD or a "Fusion Drive" at the time of purchase, there is no way to add a PCIe-based "blade" SSD later as the needed connector is not present. However, the 27-Inch "Late 2012" and all "Late 2013" iMac models do have this connector on the motherboard even without a pre-installed SSD, so it is possible to add a PCIe-based "blade" SSD after the purchase of the system.
http://www.everymac.com/systems/apple/imac/imac-aluminum-tapered-edge-faq/differ ences-between-imac-aluminum-late-2012-late-2013-models.html
One of these should work:
http://www.newegg.com/Product/ProductList.aspx?Submit=Property&N=100008120%20600 038516%20600038517%20600038515%20600489717%20600171532%20600171533%20600488413&I sNodeId=1&name=M.2
With that said you will have to completely disassemble the iMac to install an SSD blade in it. That means not only removing screws, but also glue, and other securing mechanisms, not easily removed.

IMac-27inch model (late 2012) running slow after Mountain Lion 10.8.5 supplemental update

I have the iMac 27-inch (late 2012 model), 8GB RAM, 1TB Hard Drive. All of a sudden after the Mountain Lion 10.8.5 Supplemental update it started running like molasses (apps take forever to open, takes forever to wake out of sleep, long boot up times, etc.) I ran verify disk, verify disk permissions, etc. I found that when I ran verify disk permissions, it stated that the iTunes permissions weren't right so I repaired disk permissions, reboot, still same problem. Ran verify disk permissions again, once again iTunes permissions issues, repair disk permissions, restart, same problem over and over again like Ground Hog Day, please help...

First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|find tok|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (command-C).
Launch the 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.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Reset the System Management Controller.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor 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 Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

Does this shelf fit my iMac 27 inch late 2012

Hi,
Does the Twelve South BackPack 2 Adjustable Shelf fit my imac 27 inch late 2012?
I just ordered one from apple just now and noticed afterwards (should have read it all first) that it said not compatible with imac (fall 2012) models.
Is that me? I bought the imac in January 2013, it's the new slim model. Should I cancel the order or will it fit. I wanted it to hold the USB Superdrive out of sight?
Thanks, Crankyhead.

Best Buy carries that item (at least in this area) and they also have the iMacs, so I'd suggest going there and checking it out.
FWIW, there is no 2013 model iMac; anything sold at this time is the late/fall 2012 model. As for whether it fits or not - I don't have a late 2012; I bought a backpack for my mid 2010 and did not care for it (didn't appear to be solid enough to hold a hard drive which is probably heavier than a superdrive), so I returned it.

I am planning to buy an iMac 21.5 inch with Fusion drive and 16 GB RAM while i visit USA for a conference. My country of origin is India. Once i am back to India, will my iMac be covered by the Apple's Protection Plan?

I am planning to buy an iMac 21.5 inch with Fusion drive and 16 GB RAM while i visit USA for a conference. My country of origin is India and the option of configuring to my need is not avaialble here in India. My concern is once i am back to India, will my iMac be covered by the Apple's Protection Plan if something goes wrong here in India?
I recently came across some posts regarding International warranty related issues for iPhone and iPad....hence this crossed my mind...
Waiting for response from the support group members...

Thanks Ralph
This essentially means that if my iMac develops some problem (both software and hardware) in my country (India), it will be completeley attended (even the whole system requires replacement) by the AASP in India...is that what you say?

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'.

After updating to 10.9.3 on my iMac 21.5 late 2012 trouble with sleep mode(after waking up ethernet connection is lost)

...and i have to wait when ethernet is connect

Doesn't work on late 2012 iMac because of the 3TB Fusion Drive?

I have the later 2012 27 inch iMac with the 3TB Fusion Drive. When will Bootcamp support the 3TB Fusion Drive?

Apple have not announced support yet, only they know when.

IMac (27-inch, Late 2013) with iMac (27-inch, Late 2012) in TDM issue

With the late-2013 iMac 27" (3.5 GHz, 32 GB RAM, 3 TB Fusion, Mavericks 10.9.4) as the primary and the late-2012 iMac 27" (3.4 GHz, 16 GB RAM, 3 TB Fusion, Yosemite Beta 10.10) in TDM, the screen on the target display blinks off and on (goes black and comes right back after a split second). It happens intermittently, regardless of which Thunderbolt port is used to connect the two computers. The other Thunderbolt port on the primary is used to connect two external FW800 drives via a Thunderbolt-to-FW800 adapter.
Through exhaustive testing, and in constant consultation with AppleCare senior advisors, I have seemingly ruled out all obvious potential hardware or software culprits:
An AVR is feeding both computers consistent power.
Each computer's RAM and video cards have been tested with TechTool Pro 7: everything passed.
The Thunderbolt cable has been replaced.
Reset the NVRAM and SMC on both computers (though with all the testing I've done since, it might not hurt to do this again).
Both computers have been running the latest version of OS X (the target display is currently running Yosemite Beta).
Made sure to enable TDM after the primary iMac has completed its full startup process.
Turned down the display brightness on both computers.
Trashed the com.apple.windowserver.plist file on the late-2013 iMac.
None of these steps have resolved the problem and I am having NO other issues with either computer. I'm stumped, as are the AppleCare senior advisors I've been working with. This issue has been present since I first connected these two computers this way. Design flaw not revealed in testing? Problem part not revealed in testing?
Anyone here seen anything like this or have any ideas of what else I can try? Help would be greatly appreciated!
Thanks,
Dana

Purchase a Windows PC?? Gasp, indeed! No, after months of software and hardware troubleshooting with an AppleCare senior advisor, and me refusing to believe my brand new 2013 iMac could have a hardware defect, I finally took my entire configuration (both iMacs, voltage regulator, back-UPS) in to my local Apple Store. They were able to replicate the issue, but then misdiagnosed the problem and replaced an internal display cable. Within minutes of reconnecting everything at home, the problem returned. So AppleCare sent an authorized service tech to my home to replace the logic board. That seems to have finally solved the problem. Inconveniently, the tech didn't have what he needed to flash the new logic board with my serial number right then, so I had to wait two weeks to get that done. It did finally get done though, and now all is well.
Good luck with your issue!

IMac, Bootcamp, Windows 8.1, Fusion Drive - not working

Hey there,
as many other here I habe problems installing Windows 8.1 on my iMac (late 2013) with a 3TB Fusion Drive.
I'm playing around with that installation about 3 days or so.
Even got a problem where I couldn't delete partition and suddenly got a second logical volume group
Somehow I could fix that.
I tried to install it with the help of Threads which are already opened here but had no success.
I just want a plain Windows version, not on that SSD part of my Fusion Drive, just about 500GB of Windows
And maybe there is a chance without reinstalling Yosemite?
Hopefully you can help me through that process.
And many thanks in advance, here is the output of my disk:

SMC Firmware Update 1.1 for late 2013 Fusion drive.

I'm curious as to why I'm receieving the SMC Firmware Update 1.1 for my late 2103 iMac with Fusion drive when the update states flash only. What gives?

Thanks, I understand that Fusion is part ssd and part hdd. The firmware states that it's for flash only, and not fusion. That's what led to the confusion on my part.
I checked my software updates this morning, and the SMC firmware update is no longer listed. Perhaps, Apple removed it.

I have a MacBook Pro (13-inch, Mid 2010) and iMac (27-inch, Late 2012) - can I work between both?

I have been using my MacBook Pro for several years and still use it on-the-go but at home now I have the Late 2012 iMac, I bought a Thunderbolt cable but found it wouldn't work with the MBP.
When I'm working on the laptop - and I return home - is there a way I can then transfer the work to the iMac and vise-versa.
Obviously cloud services like Dropbox exist but I'm looking for an alternative as I transfer quite a lot of files.

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'.

IMac 2009 (21 inch) making hard drive noises during sleep mode - normal??

Hi there guys,
I have an iMac 21 inch (2009) , 3ghz C2D, 4GB Ram, 1TB hard drive (the hard drive was upgraded straight thru apple, when i bought it i paid extra for a 1tb hard drive, its not a DIY hard drive upgrade)
aniways, I recently noticed that during sleep mode, occasionally (not all the time) I can hear some faint clicking / hard drive noise, which is really weird because i put the imac in sleep mode and it really shouldnt be doing that no?
My 13 inch macbook pro 2010 never does this in sleep mode, its always dead silent
Im just wondering if this hard drive accessing / clicking noise during sleep mode is normal in imacs??

Im just wondering if this hard drive accessing / clicking noise during sleep mode is normal in imacs?
No it should not be doing anything but sleeping. The SMC controls sleep, try resetting it.
Reset the SMC
• Shut down the computer.
• Detach the computer's power cord.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Reattach the computers power cable.
• Turn on the computer.

MBA 13" (2013) vs iMac 21.5" (Late 2012)

Hi, I just bought the new MBA because I needed a laptop and wanted to try out a mac and osx. I originally thought I needed a laptop because I was going to be bringing it with me all over the place but as it turns out I won't be using it at my place of work. So it's being downgraded into a stay-at-home main computer. I feel that might be a bit silly so I wanted to ask whether I shoukd return it and get something else. I was also thinking of getting a refurb MBP but then I thought about an iMac.
Obviously this is last year's model and I've been reading that Apple will probably refresh the line later this year. I'm just wondering what some of your opinions might be.
This is the iMac I'm looking at http://store.apple.com/us/product/FD094LL/A/refurbished-imac-29ghz-quad-core-int el-core-i5
How would it suffice as a main computer? Will it last for several years because it would be a shame to buy it but have the parts and system become outdated so quickly. I've looked up the graphics card but I was wondering how well it runs in general and was hoping some owners could elaborate on this.
As far as I'm planning to use this for, its just going to be mainly browsing, maybe some light gaming (depending on the power of the card), and maybe some streaming. I know for a fact that I will need to get bootcamp on there and get Microsoft Access so there's that.
I'm just curious if it was worth it to trade. Or to stick with the MBA? Or just get a cheap windows pc/laptop because all I really need is to run Access. I can probably browse on any PC and play games on my consoles.

Hi Dàmien,
it would work if you had on "older" imac with Mini-Display Port Input and and Mini-Display-Port cable (not a thunderbolt cable) to connect your MBP Late 2013 with the "older" iMac.
I can confirm that working:
iMac 2013 runs Win7 under Bootcamp and an iMac 2009 serves as 2nd screen for the Windows desktop.
In your case just replace the iMac 2013 with your MBP 2013 and that should be fine. But you need a Mini-Display-Port iMac at this point as far as I can tell.
Hope that helps.
Thanks,
Martin
