Late 2012 iMac locking on Sleep
My late 2012 27" iMac locks up every time it goes to sleep.
32GB RAM, 2GB video, 1TB HDD.
Clicking the mouse button does nothing, nor does hitting a key on the key baord.
The keyboard is wired as is the mouse. The keyboard is plugged in to one of the four USB 3.0 ports on the iMac.
The mouse is plugged in to one of the ports on the keyboard.
There is a USB 2.0 hub connected to another USB 3.0 port on the iMac. This hub is self powered and is a higher quality one, meaning it has enough power to handle all 7 ports on it.
A scanner is connected to one of the ports on the hub. The scanner is powered through USB.
An iPhone 4 cable is conneceted to another port on the hub.
There is a 2TB external RAID-1 HDD connected to one of the USB 3.0 ports on the iMac.
(2x2TB drives)
There is also an external DVD butner connected to the last USB 3.0 port on the iMac.
When ever the computer goes to sleep the only way to get it to "wake" is to phisucally unplug the power cord from the back and then plug it back in and turn the machine on...
Holding down the power button does nothing. Simply pressing does nothing...
This situation is quite anooying and very much unacceptable for a computer that costs over $3k.
Please help. There must be a solution, and not having the computer/HDD go to sleep is not a solution...Hey Ktulu9876, you're not alone, same story here.
Brand new iMac Late 2012 27 Screen, 3,4 Ghz i7, 16Gb Ram, 3TB Fusion, 2GB Graphic Card.
When it goes to sleep it never wakes up again after, i have to unplug the cables and plug them in again and then it works.
Simply unacepptable, talked to the Apple Care Hotline already, they have no clue what I was telling them,
the person from the hotline did some tricks, thore resets which are told above included but none helped.
BUT seems like the 21 also had a sleeping problem which is why the brought out an "EFI Update" on the 17.12. but ONLY for the 21 inch.
I am also very confused if I should return the iMac or wait if there will be also an EFI Update for the 27inch.
Looked all over the Internet if somebody else has the same problem but your post was the first one i found about this MAYOR problem.
Also my old usb hub (2.0) was not useable anymore, i had to get a new 3.0 hub.
Seems like this thing just needs to get sorted out but not from customers, Apple needs to take care of this.

Late 2012 iMac loses resolution after long sleep
Hi guys, 1st time post that I hope someone can help me solve.
After I wake my 27" iMac after a long sleep the text is blurred and when I look at display resolutions I only have two options (1024x768 & 800x600).
A reboot does not always solve it, a NVRAM reset works sometimes and a Safe Boot always works. During NVRAM reset the 1st screen is the normal grey but after the second chime the screen can be snowy.
Currently I have computer sleeps set to never and with the display set to sleep after 20mins, and I have not had a problem yet.
I have reinstalled mavericks (not a clean install), removed memory, disconnected all usb devices and reset SMC but still have same problem.
Anybody got any ideas?

Text is blurred .. Safe Boot always works.
Might be a font causing this since Safe Mode disables all third party fonts.
Open FontBook in your Applications folder.
From the FontBook menu bar click File > Restore Standard Fonts

I've got a 21.5 late 2012 iMac. Mavericks has been on it for about a week, and I've had to restart the computer from the power button about 10 times. I cant put it to sleep, because sometimes it will wake up, then freeze when I unlock, or sometimes it just won't wake up at all.
It has lots of weird window placement bugs too, like when I wake it from sleep all the windows are in the top left hand corner and they won't move out of there unless I restart.
Then theres the fact that I cant run my iMac under anywhere near the same kind of load that I could before. Right now I have 3 safari windows open and 10 apps and this thing is running like a dog, literally stuttering all over the place and barely useable, would run beautifully with the same load on ML.
Any way to solve these bugs or am I just going to have to roll back to ML? The only reason I installed Mavericks (well the main reason) was iCloud keychain, and the 'decen't' syncing of my pages and numbers files, between devices, but I'm not putting up with an OS that cant handle things or that freezes when I unlock my computer.I've got a 21.5 late 2012 iMac.

Late 2012 iMac Freezes every few days
My iMac has been in the Apple Store for a week with the Geniuses and they came back saying they couldn't find anything so putting this out to this community in the hope someone else can help. Here are the details.
Model: 21.5 inch Late-2012 iMac
RAM: 8Gb
Processor: 2.9Ghz Intel Core i5
Graphics: NVIDIA GeForce GT 650M 512 MB
Hard Drive: 1.12 Tb Fusion (653Gb free)
OS: 10.8.4
Software: Fairly vanilla with no MS or Adobe Apps. No system extensions or hacks installed.
Symptom: Every few days or so the iMac locks up. Certain running applications will still work but many common ones such as Pages, Aperture, App Store & TextEdit will hang when trying to open. Force Quitting them doesn't affect them. When I try to shut down the computer it goes to the grey screen and stays there. Eventually the power needs to be turned off to reboot it. This has been doing this for the last several months.
Solutions Tried:
- Fixed permissions
- Reset PRAM
- Re-install OS X
I can't replicate the crash but today it happened again. At around 3:50pm I went to the iMac and noticed that Pages wouldn't load. Force quitting the App didn't do anything. Aperture was not responding so force quit that. Still wouldn't re-open. Mail was working fine and I was able to send a test message. Safari worked fine. Launched System Preferences ok but could not launch TextEdit or App Store. Calendar opened and closed fine. Attempted to restart the Mac but got the grey screen and after 5 minutes of waiting turned the computer off & relaunched it.

Notice that the last Console entry was at 2:47pm (in red) and then nothing. I went to use the computer at 3:50pm and did several actions on it. Plugged in iPad, opened iTunes. Copied a file from the iPad to the desktop. Prior to that it hadn't been used for several hours. The shutdown that I selected does not appear in the log (although it only managed to go to the grey screen rather than complete a full shut down).
Appreciate any clues at all here. This is very frustrating and has been going on for far too long.
TIA. JordanBack up all data immediately as your boot drive may be failing.
If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below on this page to select it:

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. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. The title of the window doesn't matter, and you don't need to post that. -
Late 2012 iMac. Audio volume to zero after sleep

External display on late 2012 macmini does not go to sleep.
External display on late 2012 macmini does not go to sleep, instead the content freezes. After Pram reset it does go to sleep, till it undergoes next system sleep cycle (hibernatemode 25). I need to suspend it to disk because it is an offgrid setup and the power needs to be cut between Sessions. Display is connected to the hdmi port. Runing OS 10.8.4. Reinstalling did not help, neither. I have struggled with this for half a year now, it accured about 2 month after first use of the machine.
Thank you for possible help!Hey

Next on my list would be an installation from scracht - wich i would obviously love to avoid
The bewildering thing is that through a pram reset i can get the display to sleep once again...
Maybe a hardware prob?
Might want to check using the thunderbolt port instead, as soon as i can afford the adaptor.
Anyway i will go to offline world for some time now, on a crazy bicycle tour trough remote eastern europe.
I would love to hear from you on an occasion of a peek to cyberworld during my trip!
So long

Issue with Fusion drive (Late 2012 iMac)
I have a late 2009 iMac that has been backed up with Time Machine. I recently picked up a late 2012 iMac with the 1TB Fusion drive. When I first plugged in my Time Machine drive, I was asked if I'd like to transfer my files over. I did, and everything was working fine. I was using about 800GB of my 1.12TB Fusion Drive.
I recently decided to add a new partition to the Macintosh HD in order to put Windows on it. I did this through the Disk Utility. I noticed that it was taking an inordinately long time to create this partition. Finally, I realized that the Disk Utility was locked up. I was forced to reboot to fix it.
I went back and tried again and I got an error stating that the drive had errors and I couldn't make a new partition. So I attempted to "repair disk". That gave me an error "Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility."
So I rebooted into recovery. Recovery was absolutely no help either. It couldn't repair the drive, even though it had me erase all the data. So I downloaded 10.8.2 on my Mac Mini and made a boot disk out of my Thunderbolt drive. I booted into OS X and tried again to repair, thinking it would work since the Fusion was no longer the boot drive. No such luck. I then booted back into recovery and had recovery download and install a fresh version of 10.8.2. 2+ hours into the download/install, I get an error that says "OS X couldn't be installed because the disk Macintosh HD is damaged and can't be repaired."
Ok, so as a final attempt, I had recovery use my time machine to start over. That worked, kinda. It now shows my Fusion drive as being completely filled in Disk Utility (49KB remains, only about 800 or so was used before), and Finder shows the Fusion drive as being 860GB capacity with 837GB used. I still can't repair the disk. And now my Time Machine acts like I'm working on an entirely new computer and says there's not enough room on the drive unless I format my Time Machine drive and start over.
Yeah, TL;DR, but does anybody have any idea how I can get this issue resolved? I wonder if doing the TM restore from my 2009 iMac may have introduced the non-Fusion version of Disk Utilities that doesn't know how to fix my issue.Yes I have AppleCare.
Before that I've now made a bootable disk and tried to repair the internal drive, but this was not possible.
I have a Time Machine backup, but excluded some temporary folders.
Is there a way to access these folders in case they aren't in a damaged area?
Maybe using "Target Disk mode"?
I've never done this before.
This Mac has no FireWire, but we have an adaptor for Thunderbolt to FireWire - could I connect an older Mac with FireWire using this adaptor for Target Disk Mode?
Many thanks. -
Memory corruption due to bad RAM in late 2012 iMac
I just unpacked a brand new late-2012 iMac a few days ago. Its specs are basically maxed out, only choice being the 3TB fusion drive. To summarize:
3.4 GHz Core i7
32GB RAM
3TB Fusion Drive
2GB NVidia
Latest patches for Mountain Lion
Since I got it, I have been experiencing intermittent abnormalities with it. Programs randomly crash with error messages along the lines of "such and such file appears corrupt, please run --repair".
I do a lot of programming in my job and just today I started getting bizarre 'segmentation fault' messages in Terminal. What worked just a few minutes ago started crashing with a segfault. The exact same programs have no negative effect on my Macbook Pro and work just fine. In a matter of minutes, the entire iMac became unresponsive and I got the "we shut down your computer to prevent damage" panic screen.
After a reboot, I started thinking it could be some sort of memory corruption. I downloaded the 'memtest' utility and started the basic test with:
memtest all 2
In just a few minutes, below are the results I receive (I re-ran multiple times to the same effect).
Any opinions on whether this is indeed bad RAM? How do I handle this with Apple support? Any suggestions/comments are most welcome.
Thank you,
Ozgun

➜ ~ memtest all 2This must be my last last thing. AHT was on an iMac I bought in 2009. It was included on my "disk 2" along with several other applications. When I wiped and installed the full Lion, AHT was gone. Same is true for the full Mountain Lion installation media. It does not have AHT. I'm not at all sure how to get it back from Apple.
I was able to find it on my SL disc 2 and extract it again from that. Disc 2 won't install on Mountain Lion (the packages are too out of date) but the AHT pkg does.
Since you have it, consider packing it up and keeping it safe. Maybe someone who knows AHT better than I can elaborate on AHT. From what I've seen, you get it when your mac ships but if you ever wipe and reinstall the OS, you lose it. -
Late 2012 imac 'not enough ram' for photoshop
I have a late 2012 imac - 3.4 i7 16 gig ram and yet when using photoshop elements 9 it keeps freezing with a message saying not enough ram. Another problem which may or may not be related is MS word tending to freeze when I cut and paste??
Any help greatfully received
ThanksWell, I use PSE 11 and at least in my version I would recommend, as Adobe does, that you go into Adobe Photoshop Elements Editor>Preferences>Performance>and there I would set your RAM allocation ("Memory Useage" as they call it ) to at least around 12 GB while you are using PSE. It is heavily dependent on the amount of RAM it has available:

Late 2012 iMac Keyboard Problems
Since I got the new 27" late 2012 iMac I am having keyboard issues.
The issue mainly revolves around the number pad but sometimes the entire keyboard is affected.
So I will be using the Bluetooth wireless keyboard and mouse and everything will be fine.
Then all of a sudden the keyboard does not work. Sometime a reboot fixes it but sometimes not.
Or when I hook up the wired keyboard all of a sudden the number pad on the right does not work but the plus and minus keys do.
It is very strange and odd.
When I called Apple tech support they said go get a new keyboard so I did.
Then when it happened again with the wired keyboard being the problem I took it down to the store and they said because I had bluetooth on it could have been communicating with the wireless keyboard and getting confused.
Now when trying to use the wireless keyboard I have issues and when I use the wired keyboard I have issues.
Any other suggestions?Since I got the new 27" late 2012 iMac I am having keyboard issues.

Introduction
After I received my new iMac with a 3 TB Fusion Drive, I was disappointed when I realized that Bootcamp was not running on this model and prevented me from installing Windows on it. I wanted to take advantage of the powerful iMac hardware to play games but I couldn't.
There are a few ways of working around this limitation, but I found most of them quite complex and most of the time they required formatting the internal hard drive or repartitioning it and go for a brand new installation of Mac OS X. I was not comfortable with that.
But there is another way, and that is to install Windows on an external hard drive, using either USB or Thunderbolt. Personally I used a Lacie Rugged 1 TB drive that has both USB3 and Thunderbolt connectors. Both work very well.
This guide may interest you if:
You have an internal hard drive of more than 2TB and you can't run bootcamp at all (like late 2012 iMacs with a 3TB drive)
You have limited space or you don't want to dedicate disk space on your internal hard disk drive to a Windows installation
What this guide will make you do:
It will make you erase all your data from your external USB3/Thunderbolt hard drive
It will make you install Windows on your external USB3/Thunderbolt hard drive
It will make you install bootcamp drivers
What this will not make you do:
It will not make you modify anything on your internal Mac hard drive
It will not make you use or install the bootcamp assistant
It will not activate the Preference Pane for the default boot drive. You have to boot by pressing the ALT key to manually select your boot drive each tome you want to boot Windows.
What you'll need
An external hard drive with a USB3 and/or Thunderbolt connector. This drive will be formatted so ensure you saved your files before going further. You can use either an SSD drive or a classic hard drive.
A Windows 7 or 8 install DVD or ISO (check whether to install 32 or 64 bits versions based on your Bootcamp drivers) and the corresponding Windows serial number.
One of the following:
Mac OS X with a Windows 7 or 8 Virtual Machine (use VMWare Fusion or Parallels Desktop for example. Note: VMWare Fusion seems to have some issues with Thunderbolt and USB3. Plug your drive to a USB2 enclosure or hub to work around this -it worked for me-, or use another VM software) → Read the important note below
A PC running Windows 7 or 8 → Read the important note below
Windows AIK (free) running on your Virtual Machine or on your PC, or just the imagex.exe file (the rest of the Windows AIK package is not needed)
Download imagex.exe
Download Windows AIK (this download and installation is not required if you have already downloaded imagex.exe)
Bootcamp drivers for your Mac. You can get these either by running bootcamp from your Mac (Applications > Utilities > Bootcamp) or, if like me you have a 3TB drive and can't run bootcamp at all, use the direct download links here.
A USB stick to store your bootcamp drivers
IMPORTANT: If your Mac has a 64 bits processor, your Windows Virtual Machine on OSX, your Windows installation on your PC and your Windows DVD/ISO must also be in 64 bits!
Step by Step guide
Step 1: Get the install.wim file
If you have a Windows ISO file:
Mount the ISO
If you're on OS X: double click on the ISO file
If you're on on Windows 7: Use a software like Virtual Clone Drive (free)
If you're on Windows 8: double click on the ISO file
Open the mounted drive, then go to the "sources" folder and locate the "install.wim" file. Save this file to C:\wim\ on your Windows installation or virtual machine.
If you have a Windows DVD: open the "sources" folder on the DVD and locate the "install.wim" file. Save this file to C:\wim\ on your Windows installation or virtual machine.
IMPORTANT: If instead of a "install.wim" file, you have "install.esd", you can not continue this step by step guide. And an ESD file can not be converted into a WIM file. So you must get a version of the Windows installation DVD/ISO that has an install.wim file.
Step 2: Clean, partition and format your external hard drive
On your Windows installation or virtual machine, plug in your external hard drive (can be plugged using USB2, USB3 or Thunderbolt at this stage)
Open the command prompt in administrator mode (cmd.exe). To run it in administrator mode, right click on cmd.exe > Run as admin.
Type the following and hit enter to open the disk partitioner utility:
diskpartType the following and hit enter to list your drives:
list disk
This will display a list of disks mounted on your computer or virtual machine. Make sure your drive is listed here before you continue.Identify the disk ID of your external hard drive. Replace # by your real external disk ID in the command below:
select disk #Clean all partitions by typing the following (warning: this will erase all data from your external drive!):
clean
Create the boot parition by typing the following followed by the enter key:
create partition primary size=350
This will create a 350MB partition on your external driveFormat the partition in FAT32 by typing the following:
format fs=fat32 quick
Set this partition to active by typing:
active
Assign a letter to mount this partition. We will use letter B in our example. If B is already used on your PC, replace B by any other available letter:
assign letter=b
Windows will detect a new drive and probably display a pop-up. Ignore that.Create the Windows installation partition using all the remaining space available on the external drive by typing the following:
create partition primary
Format the new partition in NTFS:
format fs=ntfs quick
Assign a letter to mount this partition. We will use letter O in our example. If O is already used on your PC, replace O by any other available letter:
assign letter=o
Windows will detect a new drive and probably display a pop-up. Ignore that.Exit the disk partitioner utility by typing:
exit
Step 3: Deploy the Windows installation image
Still using the command prompt in admin mode (you didn't close it, did you? ), locate the imagex.exe file mentioned in the "What you'll need" section and access its folder. In our example, we have put this file in C:\imagex\imagex.exe
Type the following and hit enter (remember to replace o: with the letter you have chosen in the previous step):
imagex.exe /apply C:\wim\install.wim 1 o:
This will take some time. The Windows installation image is being deployed to your external driveOnce done, type the following to create the boot section (remember to replace o: and b: with the letters you've chosen in the previous step):
o:\windows\system32\bcdboot o:\windows /f ALL /s b:
If you get an error message saying that you can't run this program on your PC, then most probably you are running on a 32 bits installation of windows and you're trying to deploy a 64 bits install. This means you did not read the important notes in the beginning of this guide
If you get an error message on the options that can be used with the BCDBOOT command, then it's because you're installing Windows 7, and the /f option is not supported. If that is the case, remove /f ALL from the command and retry.
Step 4: Boot from your external drive and install Windows
Plug in your external drive:
If you've done all the previous steps from a Windows PC, unplug your external drive from your PC and plug it to your Mac, either on a USB3 or a Thunderbolt port.
If you've done all the previous steps from your Mac using a Virtual Machine, ensure the external drive is plugged in to a USB3 or Thunderbolt port. Using USB2 should also work but you'll get very poor performance so I don't recommend doing that.
Reboot your Mac and once the bootup sound is over, immediately press the ALT (option) key and release it only when the boot drives selection screen appears. If you did not get the boot drives selection screen, reboot and try again. The timing to press the ALT (option) key is quite short. It must not be too early or too late.
On the boot selection screen, choose "Windows" using the arrow keys on your keyboard, then press enter.
The Windows installation starts. Follow the on-screen instructions as normal. The installation program will restart your computer one or 2 times. Don't forget to press ALT (option) right after the bootup sound, and boot on Windows again each time to continue the installation.
Step 5: Install bootcamp drivers
Once the Windows installation is complete, plug in the USB stick where you stored the bootcamp drivers (see "what you'll need" section), open it and right click on "setup.exe" and select "Run as admin". Follow the on-screen instructions.If you have an error saying that you can't run this program on this PC, obviously you have installed a 32 bits version of Windows and the bootcamp drivers for your Mac are made for a 64 bits version. You have to restart the whole guide and make sure to get a 64 bits version of Windows this time!
Once the bootcamp drivers are all installed, reboot and press ALT (option) after the bootup sound to boot on Windows again. And Voilà, you have Windows installed on your USB3/Thunderbolt drive running on your Mac.
Now each time you want to boot on Windows, press and hold the ALT (option) key after the startup sound and select "Windows", then press Enter.Hi i'm trying to follow your guide, I installed windows 8 on bootcamp to do it planning to remove it after the operation is done, but i get stuck at part 3: every command i give to imagex i get a pop-up ftom windws asking how do I want to open this kind of file install.wim and imagex does nothing, what do i have to do to stop those pop-ups?

I have a late 2012 iMac with an I5 precessor running OSX 10.8.5 and a 1tb internal hard drive. I keep losing access to the internal hard drive/startup disk.
I can reboot and everything operates as normal for a few minutes or hours but then I lose all access again to anything on the hard drive. The computer is still up and running but no files can be accessed and certain websites cannot be acessed even though internet access appears to be normal. Disk utility can only find permission errors related to iTunes which can be repaired only to come back at the next scan (I would not think permission errors would have anything to do with the hard drive crashing). It does not seem to matter what program I am using at the time access is lost and it can lose access sometimes right after reboot when no program is running.You will need to boot into the Recovery Volume (command - R on a restart or hold down the option/alt key during restart and select it) to run Disk Utility/Disk Repair.

I've got a new late 2012 imac, but I realize yes it doesn't come with a compact disc drive. I have an Adobe Creative Suite CS5.5 install disc with all the information included (serial). I copied the contents of the CD into a USB Flash drive, but I can't get it to install because it is looking for the content on the CD. Since I don't want to have to buy the external Superdrive!! How do I convince the computer into installing adobe via the files on the flash drive?
Your question makes perfect sense to me. I would contact Adobe Supptrt Services from the contacts listed here:
http://helpx.adobe.com/creative-suite/kb/install-creative-suite-5-cs5.html
You will need adobe current serial number.
I hope you'll post here with your results. I've interested know what happens. -
Help for with slow, glitchy (late 2012) iMac
This is an ANSWER and not a request for help. I didn't know where to post this and apologize for stepping where I shouldn't.
I have a Late 2012 iMac that has been crashing, running slow, and now worse; all my documents and everything in Finder have disappeared. I discovered a fix that may help others with similar issues. I use my iMac for use with Logic Pro X and Mainstage where freezeups are a disaster. I thought about this awhile and realized I had installed a new USB 3.0 external hard disk a few months ago when this issue began. I began to experience more and more crashes and extremely slow performance. Beach-balls and slow performance were common. But the last straw was when everything in Finder disappeared. My Document and Application folders were empty. If I clicked on "About This Mac" I saw nothing. It took two tries to prove my theory, but here's what I did to make "the fix". I unplugged the USB 3.0 drive and all USB and external devices. I did a restore of OSX Mt Lion. All was back to normal. But after plugging in the USB 3.0 drive, all the afore mentioned problems came back. I did one more restore, this time NOT connecting the USB 3.0 external hard disk. Now I have gone some time and my iMac's speed is back to "incredible", no beach balls or any sign of slow performance in recording or running any other app. Apparently, the 2012 iMac; although spec'ed to be USB 3.0 compatible, may not be all that compatible. Hope this helps someone!Likely the external drive is bad or defective cable.
