Trouble with iMac and Fusion Drive

Hello, I recently tried installing Windows 8.1 via Boot Camp on my Retina iMac. The install was unsuccessful, so I went to Boot Camp and deleted the partition. After that, I realized I was not able to access that space on the HDD. Reading around, I ended up deleting the Logical Volume, and breaking the Fusion Drive into 2 separate drives. I have tried to consolidate them again using Disk Utility from recovery, but I keep getting an error. After this, I tried it within Terminal. I keep getting an error that the drive cannot be unmounted. Can anyone shed light onto why this may be, and how to fix the issue? I appreciate any help I can get.

I figured it out, made a bootable USB, booted to that, then rebuilt the Fusion Drive inside Disk Utility.

Trouble with kt4v and floppy drive

Just bought a KT4V mboard an XP2600 and 512mb 333mhz ddr ram
Thing is i need to update the bios to get my processor runnin at the correct clock speed but the floppy drive doesnt work:
its detected in bios and everythin seems to be ok until i try and use it, the green light on the front of the drive stays on all the time (starting as soon as the power is on), even when theres no disk in it.
Has anyone had any diffculties like this, ive checked the cables but not sure if ive forgotten to connect something up on the mboard??
any help much appreciated, thanx

Hi,
I pulled a 3 year old Fully Working floppy disk drive from an Asus mobo,tried it in a KT3V and now my KT4V-6712,Exactly the same problems as you Manoah,also tried 3 diff cables,(you must use the one provided,red?).
I suspect a "factory fresh" disk drive needed,anyone know any compatable brands?

IMac Retina 5k Display with 6 TB Fusion Drive

For no good reason Apple offers no BTO option for build-in state of the art 6 TB hard drives as Fusion Drives in the Apple Online Store. Those drives work as Fusion Drive without any problem in customized iMacs already. I have seen it! So why leave out this option? Is there any way to get a BTO Retina iMac with 6 TB Fusion Drive? Maybe a premium reseller?

Were you able to resolve this? I have the same issue and the marks look almost exactly the same...
Called Apple Care and they told me to take it in to an Apple Store, which I'll do after I backup everything.

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.

Basically when trying instal win 7 via iOS maverick when reboting and windows booting to the first scree everything freezing cant do much.

No, unfortunately, when you format a drive, it will erase all the contents. So you will need to find a temporary "storage" place to put the stuff using a PC so you have access to it. Then reformat using Disk Utility (Applications > Utilities). If only using with mac, format Mac OS Extended (Journaled) and use GUID Partition scheme under Partitions/Options. After formatting, you can drag the files back.

Trouble with my DVD/CD drive/slot.

I am having some trouble with my DVD/CD drive/slot. It will not accept any CD's or DVD's that I have tried to insert. I have tried restarting the computer and updating software. Does anyone have any ideas that may help? Thanks

try doing a SMC reset and see if that makes your CD/DVD work again.
if that doesn't work, try a PRAM/NVRAM reset.
if not, make an appointment with apple to have them look at it.

Is there a pro code for a new imac and super drive?

Hi ..
No, there isn't but you might want to take a look at refurbished iMacs > Refurbished Mac Computers - Refurbished Notebooks & Desktop Computers - Apple Store (U.S.)
Refurbished products come with the same one year limited warranty as does a new product.

I am having all kinds of trouble with itunes and updating my ipad. when I open up itunes, it seems to just sit there, never going to itunes store. when I connect my ipad, I check update and it starts, but then I get this message:backup can't be saved on

I am having all kinds of trouble with itunes and updating my ipad. I open itunes up but it doesn't do anything except open to a blank screen. I try to access the itunes store but it won't go there. When I connect my ipad, and try to update it, it starts and then I get a message that says backup cannot be saved on this computer. I have tried everything suggested to no avail. This is the 2nd or 3rd time I have had problems with itunes. Sometimes I even get a message that I am not connected to the internet.
I have uninstalled and re-installed. Any help?

You might not have enough space left on your hardrive.

I have two Apple IDs - one associated with iPad and iPhone and the other associated with iMac and MacAir. I am going to lose the former e-mail address imminently and would like to associate all devices with just one ID. How do I do this? Thanks

Thanks - I guess it is like there were two of me!
I bought the iPhone first and it seemed natural to link it to the (work) e-mail address which was in constant use. The iMac for home use came next and it seemed natural to use my home e-mail address, particularly as I knew by then that I would lose the work address after my imminent retirement. The same logic went for the recent puchase of the MacAir. I am not sure what happened with the iPad (also a recent purchase) - iTunes seemed to puch me towards the same ID as the iPhone.
It is not a huge problem - just makes my persona look schizoid! Otherwise very happy with everything Apple.

I downloaded Firefox 4.0 and it says to re-install the toolbar but I have not been successful in doing so. Can I go back to the older version? I had no trouble with that and I do not like this new version at all.

I downloaded Firefox 4.0 and it says to re-install the toolbar but I have not been successful in doing so. I went to the forums and tried all the suggested fixes but none worked. Can I go back to the older version? I had no trouble with that and I do not like this new version at all. I tried a system restore twice and it did not fix the problem.

I would imagine it's the MyWay Searchbar which is classified by most anti-malware scanners as adware, or even worse as spyware. I say that because I see "SmileyCentral" in your list of plugins and that's an add-on for that particular toolbar. You can disable that via Tools | Add-ons | Plugins.
There are a number of toolbars which won't work with Firefox 4 anymore due to the enhanced protection mechanisms in the browser.
Mozilla recommends that you only install add-ons from its own security site @ https://addons.mozilla.org/en-US/firefox/?browse=featured Generally speaking, those have all been tested and approved. The exceptions are those currently under review which are marked with a yellow banner to warn users that they haven't passed Mozilla's labs yet.
