2012 iMac

My PC is now having issues - stalling out and requiring a reboot often. Seems to be after recently installing a Western Digital back up drive on iCloud. Sometime backup fails and it reinitiates after a reboot but programs are stalling out and not responding. Virus? Any suggestions are appreciated.

Seems to be after recently installing a Western Digital back up drive on iCloud.
I don't know what that means. iCloud is not something you can install a drive on.
In any case, this is not a virus, or any other kind of malware. That should be the absolute last thing you think of when having a problem like this on a Mac.
First, since this sounds like it started when you got a Western Digital external drive, did you install the Western Digital software that came with the drive? If so, you should remove it immediately. That software has been known to cause problems, including data loss, in Mavericks. Although it has been updated, you probably don't have an updated version, and you really don't need that software in the first place. Just uninstall it.
If that doesn't help, you may have a damaged system or even a failing internal hard drive. Be sure that you have good backups of all your data, and then contact Apple for assistance if you don't feel confident in handling these kinds of issues.

[Guide] Install and run Windows 7/8 from an external drive without using bootcamp (works for late 2012 iMacs with 3TB drive)

This is a copy of a post from my blog, you can also Read it on my blog...
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 running osx 10.8.5. I keep losing access to my internal hard drive. I can reboot and regain access and it will last for a few minutes or hours. Disk utility does not seems to help.

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.

2012 iMac 27" fails to boot AND wake from sleep

Hi all,
My 2012 iMac has recently started giving my trouble when booting and waking from sleep.
When booting - A normal power up results in the apple logo screen being stuck, then I have to hold down the power button for a few seconds until power off, then i power it back up and the computer boots up normally. NOTE: only at the second time does the computer succeed in getting past the apple logo screen to the sign in screen.
Waking from Sleep - When ever the mac goes to sleep he doesn’t seem to be able to wake up. Usually stuck on a black screen with just the spinning wheel shown. At times i waited more then an hour to see if he can get passed the black screen but in vain.
Other then that the mac works fine.
Both issues started roughly two weeks ago and roughly at the same time.
My mac is mostly used for work, I'm familiar with computers so I am trying to be extra careful with installing weird applications but you could never know..
SPEC:
Late 2012 iMac 27'' - 3.4 Ghz i7.
16GB RAM.
1TB Fusion drive.
2GB NVIDIA GTX 680MX
Wired keyboard and a Magic mouse.
Mountain Lion 10.8.5 (Updated and backed up on a regular basis)
Things I've tried:
Boot to Recovery and Repair Disk/Permissions.
Safe Boot.
SMC reset.
PRAM reset.
* The first two produced a single case of a normal start up, but after a shut down the problem remains.
Any ideas/thoughts/help would be much appriciated,
Thanks in advance,
Idan.

Bump.

HT3258 I have a Brother MFC-J4610DW and can't get it to print from my 2012 iMac over my lan.

I have a Brother MFC-J4610DW and can't get it to print from my 2012 iMac over my lan. It works with the macbook pro and iPad. The dialog box states "Setting up 'BrotherMFC-J4610..." Unable to communicate." I worked with the AppleCare guy for a couple of hours. We got it to print via USB but when we switched to ethernet hook up via Time Capsule it won't communicate or install the printer.

Try two things (separately, trying to add the printer in Print & Scan/fax prefs after each):
Reset the printing system:

Installing Adobe Creative Suite - NEW 21" late 2012 iMac - Don't want to buy superdrive!! How can I trick the computer into thinking the USB drive is a CD?

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.

What's the best way to move files from my 2012 iMac to my 2014 MBP?

What’s a good way to move files from my 2012 iMac to my MBP?
I prefer to do graphic work on my 21-inch iMac (2012 version). But when I travel I need to copy files to my 2014 MBP. I learned that my 2012 iMac is too old for use of AirDrop, so I’m copying and moving files with a flash drive. That seems slow and clumsy. Is there a better way?

Target Disk Mode would provide a direct connection between the two Macs:

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.
Here is a snapshot of some Console entries:

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. Jordan

Back 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:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|Previous Sh' | 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. 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.

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.

I have a late 2012 iMac and a late 2009 mac mini. I want to know if I can take the 8 GB of ram from the iMac and install it in my mac mini.
According to Cruicial my mac mini could use:
Module Size: 8GB Kit (4GBx2)
Package: 204-pin SODIMM
Feature: DDR3 PC3-8500
Specs: DDR3 PC3-8500 • CL=7 • Unbuffered • NON-ECC • DDR3-1066 • 1.35V • 512Meg x 64
Also According to Cruical my iMac uses:
Module Size: 8GB Kit (4GBx2)
Package: 204-pin SODIMM
Feature: DDR3 PC3-12800
Specs: DDR3 PC3-12800 • CL=11 • Unbuffered • NON-ECC • DDR3-1600 • 1.35V
I want to increase the ram in both computers.
So, can I put the iMac ram in my mac mini and then I'd only have to buy ram for my iMac? Naturally the ulitmate test will be when I actually install it, but having an expectation of success or failure will allow me to plan on what to spend money on.
Thanks,
Bear

Thanks for the responses. I probably wont even try as my priority is Ram for the mac mini. 2 is not enough. 8 for my imac is okay for now.
Somewhere I thought I'd heard that faster Ram would simply clock at the lower speed. It seems that I am incorrect.
Thanks,
Bear

2012 iMac as external monitor

Hi, got 2012 imac that I want to use as a external monitor from my PC with has displayport out.
From research I see that to use it via HDMI or DVI you have to make sure you get an expensive bi-directional cable, but all the cables I can see are just called mini-displayport to displayport, where as I want to go from displayport to mini-displayport.
Do I need to a different cable or are mini-displayport to displayport cables bi-directional?
Cheers

Can 2012 iMac be used as monitor for PC with thunderbolt?

Hi,
Im planning on buying a new 2012 iMac and was wondering about TDM - Target Display Mode.
My PC rig is up for a new motherboard and the thought was to buy a thunderbolt equipped one and then use my shiny new iMac as display for it.
That way I can switch between them easily and only use the one screen. I know Apple support pages tell you that any thunderbolt equipped mac can use the iMac in TDM but what about a Windows PC with thunderbolt motherboard?
Any help is appreciated!

It'd run better too.
That is fine If he has a Non Branded install of Windows on his PC. In other words a Retail copy of Windows installed on his PC. None of the Virtual Machine programs let you import a Branded installl of Windows. That is Totally against the license terms. When I say Branded I mean a version that came with the PC from makers like Dell, HP, Sony and the like. Those versions are for those specific brand of PCs and can Not be moved or installed on other hardware, virtual or physical.
And to your comment that it will run better on a Mac is just completely false. No OS runs better in a Virtual Machine then it does on it own set of physical hardware. Not only that but if you use Boot Camp to install Windows on it own partition on the Mac the Mac still has limiting factor invovled that are not present when running on Real Windows PC hardware.

Using 2009 iMac as second display for 2012 iMac

I am using my 2009 iMac as a second display using a mini display plugged into the 2012 iMac Thunderbolt port. When I plug it in, it works fine, but if I need to restart my 2012 iMac, it won't recognize the second display on reboot.
How do I make my 2012 iMac automatically recognize the second display? The only way I seem to make it work is by unplugging the cable, and then plugging it back in. When I do, it immediately recognizes the second display.

Thank you. Here's where my confusion comes in

Late 2012 imac bootcamp error"Non system disk, press any key to reboot"

Hey all,
I'm having all sorts of issues with getting windows 7 installed through bootcamp. I have the late 2012 imac 27 inch fusion i7 16 gigs of ram 680gtx. I downloaded the latest bootcamp drivers to my usb after i re-formated it. Partitioned the drive 200 gig windows 700 gigs mac. It restarts and then i get this error screen, "non-system disk.(see photo below) Press any key to reboot." which of course is unresponsive. I hard reset with the Option held into boot back into mac. I'm using Windows 7 64 bit. Please, any help would be appreciated. I have a unopened copy of Bioshock Infinite waiting for me

The Macs with a built-in Optical drive use the Windows DVD, because that is what BC tells it to be set to. The USB is not made bootable on such machines.
The exceptions to this rule are (from Boot Camp 5.1: Frequently asked questions)
Can I use a downloaded (ISO) version of Windows with Boot Camp?
MacBook Air (Mid 2011 and later), MacBook Pro (Mid 2012 and later, including Retina models), Mac mini (Mid 2011 and later), and iMac (Late 2012) can install downloaded (ISO) versions of Windows 7 and 8.
