NO AUDIO - (Late 2013) iMac with Windows 7 64-bit

Hey everyone,
I have been scouring the forums to find something that will help me, but I have yet to find anything that works.
Here is my problem:
I recently installed Windows 7 64-bit using bootcamp on my (Late 2013) 27" iMac. I have the latest drivers for both OSX and Windows 7, and I used bootcamp 5 to install them. But I have NO AUDIO whatsoever, and I can't seem to find anywhere what audio controller I actually have. I tried using a bluetooth headset as a work around, but windows couldn't find any drivers to install it. It's supposed to be "plug and play", at least wireless and play. No drivers should be needed. This makes me think that I'm missing any audio drivers at all, and I have no idea how to fix this with the very little info I have on what's actually inside my mac. Any help with this would be great. It's getting very frustrating.

have you tried looking in devices under windows?
unrecoqnized devices should have a yellow !

My Late 2013 iMac with Yosemite 10.10.2 randomly shuts down and displays a grey screen with a flashing question mark folder. According to Disk Utility, my drive is OK. What should I do?

I've had this problem for a while and I thought it went away. I've looked at all of the other discussions and tried what they suggest, nothing. I preferably don't want to erase everything on here. Is there a way to fix it without having to do that? I also noticed that other people have the screen when they first boot their computer. Mine are in the middle of a college essay or browsing online. I would really like to fix this issue. I haven't even had my iMac for a year yet. Any suggestions?

Question (?) Mark, Blinking Folder, or Gray Screen at Startup
These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by one or more of these:
a. Problem with the computer's PRAM - See Resetting your Mac's PRAM and NVRAM.
b. Boot drive's directory has been corrupted - Repair with Disk Utility.
c. Critical system files are damaged or deleted - Reinstall OS X.
d. The disk drive is physically non-functional - Replace the hard drive.
Note that the information I have provided is what Apple recommends, If other users suggest different solutions than found here, then be sure what they recommend does not impact on your warranty, if any, or ability to get continuing Apple service.
Please don't start removing drives or changing cables unless you know what you are doing and have exhausted other non-invasive alternatives outlined here. If you perform any work yourself that is unapproved by Apple, then you will void any warranty you may have and lose all further Apple Support.
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD. Simply boot from the Recovery HD to perform the above.
Reinstall Snow Leopard Without Erasing The drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.

2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing The Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button.

Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Limited WiFi on late 2013 iMac running Windows 8.1 Enterprise

I was able to connect to my wireless network, it got the DNS settings(IP, default gateway and so on) but no internet. I've tried deleting/reintalling the Broadcom Wireless ac driver multiple times from:
http://support.apple.com/kb/DL1638
to no avail. I'm at the end of my tether on this.

I'm getting this too, and tried all the above to no avail.
I get a couple of minutes of connectivity and then it will drop out, until I either reconnect or get Windows to resolve the problem where it says it was due to the default gateway not being available.

Installing Windows 7 on Late 2013 iMac w/ Fusion Drive

Sorry in advance for the long post, but I have tried to exhaust all possibilities, and bring as much knowledge about our environment to the table to avoid confusion.
Here's our goal: Install Mac & Windows on a Late 2013 iMac with a 1TB Fusion Drive
Install our Mac Image with Deepfreeze on Partition 1
Install our Windows 7 x64 Image with DeepFreeze on Partition 2
Here's why our goal cannot work out of the box:
Deepfreeze for Mac, is not supported on a Fusion Drive. Now before anyone says "just don't use deepfreeze"...we are using it, and that is that.
In order to get our existing image to work on the iMac, we had to split the Fusion Drive.
Splitting Up the Fusion Drive
We booted into Recovery, Opened up terminal, retrieved the LvGUID, deleted it, and split up the SSD from the HD.
So now, we have a 128GB SSD, and 1TB HD showing up under Diskutilitiy.
We then partitioned the 1TB HD, into two, 500GB Partitions. One for Mac OSX 10.9.4, and the other for Windows.
The 128GB SSD is going to be used for scratch space, temp, etc. And is irrelevant at this time.
Deploying our Mac Image
After splitting the Fusion Drive, we netbooted and installed a "NetRestore" of our image. Worked completely fine, no issues. DeepFreeze Works fine, the 128GB SSD shows up just fine, and the other 500GB Windows Partition shows up fine. All drives / partitions can be written to with no problem.
Deploying our Windows Image
Deployed our Windows Partition image as we have done in the past, by booting into a windows PE Disk. (We have other various 2009, 2010, and 2011 iMacs across campus, with NO FUSION DRIVES installed, and dual boot them successfully using the same procedure. Minus the splitting of the fusion drive part of course) After the Windows image is deployed to the windows partition, we then boot it up to a Windows 7 Install disk to fix the MBR, Bootrec, and BCD options to allow it to boot properly. Here's where we run into issues: Upon getting the Windows 7 Install screen, the USB Keyboard and Mouse, DO NOT WORK.
Here's the options we've tried to get them to work properly
1. Tried another known working Mac USB Keyboard & Mouse = Failed
2. Tried a known working Windows Keyboard & Mouse = Failed
3. Plugged Just a known working Mac Keyboard into each USB Port to see if recognized = Failed
4. Plugged Just a known working Windows Keyboard into each USB Port to see if recognized = Failed
5. Plugged Just a known working Mac Mouse into each USB Port to see if recognized = Failed
6. Plugged Just a known working Windows Mouse into each USB Port to see if recognized = Failed
7. A Windows 8.1 Recovery USB will boot and the USB Mouse & Keyboard are recognized and installed! (YAY!!) However, we cannot repair a Windows 7 install with Windows 8.1..
BootCamp Drivers & Support Media
Downloaded the Current BootCamp Support drivers to enable the USB and other various drivers to be loaded during setup (Placed the $WinPEDriver$ and AutoUnattend.xml, and BootCamp folder on the Root of a USB, and modified a Windows7 Installation disk and placed on the root as well) The drivers do not load. Have also placed on a brand new USB2, and USB3 flash drive formatted at FAT32, to see if that made a difference, which it did not. The BootCamp USB made within Mac, it loads saying "Now booting into Boot Camp Assistant Created USB Drive..." or something like that (Don't remember the exact Message)
Side Note:
Restored Fusion Drive to its original State, and booted from the BootCamp USB drive, still no usb Mouse & Keyboard Support.

Cannot install Win 8 on a late 2013 iMac using bootcamp on 10.9

I'm trying to install Win 8 on a late 2013 iMac (purchased a couple of months ago)
I have a win 8 pro DVD, but obviously there is no DVD in this iMac. I usally use the DVD drive in my older 2009 iMac for any disk based installs but I can't appear to use it here.
I followed the instructions and downloaded a Win 8 Pro ISO from Microsoft to use with my authentication code, created a bootable USB using bootcamp, created the partition and rebooted. Once I'd entered the code I get to the install location but it says I cannot install on the partition created by bootcamp. Even if I format the partition it says I need a GPT drive but I have MBR, so won't let me install.
I tried several suggestions including creating aprtitions in various other programs and once I even got past that screen, but as soon as it tried to install I got another error saying the MBR was formatted incorrectly and it failed.
I had no issues installing Win 7 via bootcamp on the older iMac, but this one has me stumped. I used to think I knew a bit about computers, but I'm fairly new to Mac related issues as the older iMac has always just worked.
Any help would be greatly appreciated.

Hello,
I just installed Windows 8.1 on my Late 2013.
There are just a couple of things I had to do that deviated from the Boot Camp Installation Manual.
1. I downloaded my copy of Windows 8.1 as an ISO image AND as a bootable USB from the Microsoft site.
Not sure why I did that but it came in handy because Bootcamp was taking a very long time to copy the ISO onto the USB stick..
The ISO copying seemed to freeze up, but it's likely that it was just taking a long time, probably 20mins.
So, instead of waiting, I took the contents of the the USB startup stick and simply moved them over to the stick that Bootcamp had formatted for the ISO copy (I cancelled that copy function and deleted any files that had copied but didnt complete).
Once that was done, the machine rebooted from the USB stick and began the normal Windows setup process.
All went very smoothly except that my mouse was not working.
2. To get around the mouse issue, I simply plugged in a MS USB Mouse and it worked immediately.
The Bootcamp manual advised that the way around this was to 'click in upper right corner and search for Bootcamp'. Problem was, it was nowhere to be found.
So, using my MS mouse, I navigated to the 'DESKTOP' icon in Win 8.1 and found File Explorer, which showed my USB stick connected along with Bootcamp and the MS Support File (i.e. All the Apple Drivers).
I began manually clicking on all the driver files until realizing that there IS a Bootcamp executable which will automatically install the drivers for the Nvidia card, keyboard, camera, mouse, etc....
Once that was done, my installation was completed.
The entire process took about an hour, but now that I've done it, it really shouldnt take much more than 45 mins.
I have the late 2013 iMAC, with the GTX780M and 1TB Fusion Drive i5 Quad Core.
For those who are leery about doing this, please note that I'm a PC 'lifer' and this is my very first go-around with doing anything on an Apple product.
It all went much more smoothly than I could have imagined, but if you are not a PC person, you might be a little challenged finding the Bootcamp in File Explorer or doing anything in Win 8.1 to get over these minor hurdles.
Good luck!
I'm looking forward to getting STEAM up and running to see how this thing games!

More frequent Kernel Panics on late 2013 iMac

For the last couple of weeks I have been experiencing random iMac restarts with the kernel panic message (http://core0.staticworld.net/images/article/2013/02/kernel-panic-pre-ml_300-1000 24407-medium.png). I have not installed anything suspicious, I have verified the HDD, everything is ok, done the hardware test after a restart (the D button) with no issues found and when I go to the Library, Logs there is no kernel panic report nor any other information on the issue. It seems as the aforementioned message just appears, the iMac restarts and comes back to normal without any additional problems/problem information.
I have late 2013 iMac with os 10.10, everything up to date and fabric Ram memory with a lot of free space on the HDD.
I would really appreciate if someone could give me some pointers or let me know what this could be. Thanks a lot!

Graphics related crashes since Yosemite on a 27' late 2013 iMac

Hello all,
My 27 inch late 2013 iMac with a NVIDIA GeForce GTX 775M 2048 MB started freezing or auto-rebooting since I updated to Yosemite.
Crashes would occur randomly and were sometimes accompanied by lots of red boxes on the screen.
These kind of crashes seem to have stopped happening but now shifted to almost everytime I fire up Launchpad or Expose (and once when I opened the notifcation center). The screen freezes for a couple of seconds and the system will reboot, prompting me with a graphics related error.
Because my searches on this issue come up empty I would like to ask if anyone can tell me whether or not this is a bug or a hardware related problem.
Thanks for any help
Maybe related: My iMac sometimes takes a more than usual amount of seconds to wake from sleep. The screen will turn on but remain black.

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
5. Reinstall Yosemite from Scratch:
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
How to Clean Install OS X Yosemite
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.

Mac OSX Mavericks 10.9 firewire audio problem on RME Fireface 800, MOTU 828 Mk II and Apogee Duet on late 2013 iMac i7

I just got the late 2013 iMac 3.5GHz Intel Core i7 and all my firewire based audio interfaces do not work properly although I upgraded to the latest drivers. iTunes or Youtube can play for a short and then there are unbrearable digital noises.
Apogee Duet is slightly better that can play for a few minutes. Then it may have short pause or digital noises. I need to reset the "Sample Rate" to other values to get it work again.
MOTU 828 mk II and RME Fireface 800 are having the most serious problems. Alternating the sample rate can sometimes help but often I need to reboot the iMac to get it work again. However, it works for only 1-2 minutes before the digital noises.
These are the software/drivers I installed:
- Apogee Maestro 2 version 2.8.8
- MOTU Universal Audio Installer for Mac OS X version 1.6.58373 (8/20/2013)
- RME version 3.19, firmware 2.77
I connect the fireware through Apple Thunderbolt to Firewire convertor.
These drivers are supposed to work with 10.9 but they don't. Anyone can help or share experience?

I've read in other forums that there are two issues that is causing this problem of chopping audio and freezing interfaces. One has to do with USB 2.0 /USB 3.0 issues in OS. The other seems to be an issue with the Fusion drive.
The fix for the fusion drive issue that has been shared online is to either:
Option #1. Don't use the fusion drive and create an external boot drive clone (either SSD or standard HD) and use as your primary drive (completely surpassing the internal fusion drive).
Option #2. Split the internal fusion drive. From there you can use them as two separate logical drives. Load your OS on one of the drives (SSD or HD). http://www.macworld.com/article/2015664/how-to-split-up-a-fusion-drive.html
Before, you do any of the above, make sure that you backup your current system setup.
I just received my imac (2013) with 3TB fusion and I plan on trying option #1. I bought a 3TB external USB drive which I plan to clone after I have the machine running. Once I clone the internal drive, I will test how the machine runs from both the internal fusion and the external to prove if this addresses the audio clipping/stopping problem. Hopefully, Apple will find a fix for this.
It is really a dissapointment that a brand new $2500+ machine and software was not tested to perform something that my 2008 MacBookPro and my home built Window XT machine (circa 2003) did without issue. I wished that I would have checked the forums about these issues before I purchased the machine.
You can do some searches online and find even more detail discussions on this topic.

Problem installing Windows 7 64-bit on late 2013 iMac 27"

Is Windows 7 64-bit compatible with this computer?
Hardware and software:
• Late 2013 iMac 27", 3.5 GHz I7, 16 GB memory, 1 TB hard drive (no fusion drive)
• Mac OS 10.9.1
• USB thumb drive
• Boot Camp Assistant 5.1.0
• Windows 7 64-bit install disk iso image downloaded from Microsoft
Install steps:
1. Use Boot Camp Assistant to install Windows 7 install (from iso image) and Apple Support Software (creates WININSTALL USB drive)
2. Use Boot Camp Assistant to create 50 GB Windows partition on iMac internal drive and start Windows install
3. Complete initial install steps until given option to select install partition
4. Select 50 GB partition. Error message that partition is not formatted correctly. Use Advance Options to format (presumably to NTFS)
5. Select 50 GB partition again and click "Next"
6. Get error message "Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information."
7. Install quits at this point
I have successfully installed Win 7 on another computer (2010 Mac Pro) using these steps. I also tried installation on the iMac using an iso image created from my original Win 7 64-bit install disk, with the same installation error as above.
I'm wondering if Windows 7 and/or Boot Camp is compatible with this iMac. Any suggestions will be appreciated.

I am awaiting delivery on the exact model you have and have been researching how much trouble it will be to put 64 bit windows 7 ultimate on my machine when it gets here. I'm not pleased at what I've been reading so far. I have not seen the two other posts but yours is enough to concern me.
Have you also seen that 10.9.1 update may be responsible for this? I've seen where 10.9 caused some problems with the bootcamp app but then the process was completely hosed with the 10.9.1 update. Are you seeing this as well?
Being a life-long mac dude, it pains me when their stuff just doesn't work because it usually just does. ****, that's why I started on a mac in the first place.
The support site says that they come with 90 days of complimentary support. Is this not an issue they should be responsible for addressing via support? Or is that just one long wait on hold waiting to talk to somebody that won't consider this a pure apple issue?
I was also curious if your install .iso contains both 32 and 64 bit versions?

Cannot install Windows 8.1 on Late 2013 iMac

Attempting to install Windows 8.1 (retail) using Boot Camp Assistant but when I get to the "Select disk to install windows" screen, nothing appears.
I'm using a retail copy of the Windows 8.1 full installer DVD and I have the midrange 21.5" late-2013 iMac.

Installed my retail copy of Windows 8.1 from Windows 7 without any hiccups or hacks. Windows 7 can be installed in trial mode for free and easily by downloading a legal ISO from Digital River. Create a USB installation with Boot Camp Assistant and proceed as normal using the Windows 7 ISO. During Installtion, skip entering a license. After Windows 7 is successfuly installed, boot back into OSX and create just a drivers USB using Boot Camp Assistant. Boot back into Windows, insert your retail Windows 8.1 disc or use your download and let it install. Be prepared to do several "Hold-Option" boots to kick it into windows. Installation probably had 6 reboots.

Repair Windows 7 on a 2013 iMac with USB 3 issue

Hi. I have a corrupt Windows 7 parition on my late 2013 iMac that Disk Utility can not seem to repair. My best guess is a the 'Repair Windows' from the install disc upon booting up will fix the issue. The problem is....my 2013 iMac only has USB 3 ports available and from what I am reading it appears Windows 7 does not support USB 3. Therefore....my external CD drive is not being seen, nor are my keyboard, mouse, or anything else via the USB 3 ports (I also tried a bootable flash drive with the neccesary Windows files on there). I even went as far as making a bootable SD Card and trying to repair from that, but I still can not utilize my mouse and keyboard to advance through the prompts.
I did not have these issues when I installed it using Bootcamp because I am guessing bootcamp supplies the neccesary means to allow the USB 3 ports to be recognized. But Bootcamp does not have a feature for repairing windows. It is only giving me the option to remove Windows.
Is there anyway I can repair windows using my Windows installation CD on an iMac by means of using USB 3 ports?
Thanks in advance.

For attempting to repair a Windows 7 partition you need to be able to boot into Windows setup indeed. The complication is that Windows 7 installer has aged and does not support the relatively new USB 3 standard.
I can only this of one approach which is by downloading the available Windows ISO and use USB instead of your DVD. It is kind of a long shot and does have its risks, but I'll describe it high-level nonetheless:
- Using Boot Camp create an USB with Windows 7 edition you run as well as the appropriate Windows Support Files from Apple
- From OS X or the Mac's Recovery Console you could shrink your HFS+ partition for about 3 GB to create some free space
- Insert an additional primary partition in this free space and format it FAT
- Sync this GPT change to MBR manually using fdisk and reboot into OS X
- Pre-copy the Windows PE driver folder onto this new FAT partition to overcome the USB 3 issue
- Reboot in legacy bless'd mode to your USB recovery stick
The Windows setup screen should display an option to repair instead of install... Your mileage could vary depending on the type of corruption(!)

USB Audio Problems Late 2013 iMac - Clicking / Popping / Dropouts

I am having audio clicking and popping issues with a brand new late model 2013 iMac and a USB 2.0 multi-channel audio recording interface. Here is what I have learned so far:
Clicking and popping is occurring in both directions - playback and recording. I am not having any issues with internal audio, so this was easy to verify.
The same issue appears in many threads in Apple Support Communities and in various recording/pro audio forums, so this seems to be a common issue.
The issue is independent of the audio interface that is used. (I am using a brand new Focusrite Scarlett 18i20 that I purchased specifically to use with my new iMac, but the forums report the same issues for a variety of other interfaces and audio devices.)
Five potential root causes are mentioned in the various forums:
1) USB 3.0 compatibility issues - poor backward compatibility or other issues
2) Fusion Drive activity - artifacts caused by drive "swapping"
3) OS X version - newer versions may be worse than old versions
4) App Nap - ?
5) Driver issues
Potential short-term solutions include:
1) Change driver - The "Class Compliant Mode" app (that I downloaded from the link on the Focusrite website) improved the issue for me, but clicking and popping occurs every few seconds instead of constantly.
2) Exchange the Fusion Drive for a conventional 7200 RMP hard drive - Forums report that this does not fix the issue.
3) Install older version of OS - Forums report that this does not fix the issue.
4) Disable App Nap - Forums report that this does not fix the issue.
5) Belkin Thunderbolt express dock - Forums report that a Thunderbolt hub with USB gives excellent results, but the only one I am aware of is the Belkin one which is ~$300. (I will not pay $300 to fix thousands of dollars of new equipment that should not need to be fixed!!!)
6) Apple Care's advice was an SMC reset (essentially a reboot), which clearly did not work. The person that I talked to was not aware of this being a known issue.
I am at a point where I need to decide whether or not to get a refund for this iMac since my primary reason for getting this new computer was recording. So...can anyone help to answer these questions:
Has Apple acknowleged this issue? If so, has Apple committed to fixing this issue via a software upgrade or have they admitted that this is a hardware limitation that is not fixable?
Has anyone found a free or inexpensive workaround (i.e. not the $300 Belkin dock) that completely elimiates this issue?

I'm also having audio issues on my new late 2013 iMac via the USB headset. Audio starts playing fine and then static starts creeping into the audio until it drowns out the sound. Only way to fix is to unplug the headset and then plug it back into the USB port.
I've tested the headset on other PCs and my older iMac and the issue doesn't show up.
I've re-installed Mavericks on the iMac, without nuking my data, but that still doesn't solve the issue.
I've logged a case with Apple support and they had me run a program which gathered up a bunch of information to send to their engineering team. No updates yet so far.
Just one question for those that also have this issue. Did you restore your data from a Time Machine backup, or is this issue also happening on the Mac that's fresh out of the box?
I'm wondering if this issue could be caused by restoring data from my Time Machine, but I don't want to go through the hassle of nuking my entier hard drive and having to reinstall everything from scratch just to fix this issue.

[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?

Problem with not enough resolutions Late 2013 iMac 27"

Hi guys.
Last friday arrive to my home my new top iMac --> i7 / 16Gb / 3Tb FusionDrive / GTX 780
I always use 1920x1080 resolution display in my older iMac Mid 2010 27" but in my new iMac say this:
I need 1920x180. Is it possible change the resolution with scrips or edit one file...?
Thanks

Might be primitive, but free, and does the job.
the truth is you're right. Sometimes we search any solutions but this is some complicated when the best fix normally, It´s easy solution... "Okam's razor"

I have a late 2009 iMac, with a Nvidia 9400 Graphics card. I was wondering what my options are for upgrading. I use Windows 7 via Bootcamp, so I need a card that is compatible.

I have a late 2009 iMac, with the default Nvidia 9400 Graphics card.
I was wondering what my options are for upgrading. I use Windows 7 via Bootcamp, so I need a card that is compatible/has available drivers.
This is for gaming. On the lowest settings of "Call of Duty 4", I get about 100 FPS... Was hoping to be able to play on higher resolution w/o the fps lag.
I'm not good with the hardware part of computers at all, but know how to get around the OS.

In most cases the graphics cards in iMacs are Not upgradeable. They are usually soldered to the logic board. RAM is considered, along with harddrives, the only component that is upgradeable in an iMac, unlike in PC's. So basically you would need to sell your unit and purchase an iMac with a more powerful graphics card.
Hope this helps
