  In the OS X Utilities screen, select

  Utilities ▹ Terminal

  in the menu bar at the top of the screen, not one of the items in the OS X Utilities window.

  Follow the steps in this thread to ASC to split the fuser unit. The long string of letters, numbers and dashes you will need to enter will be different in your case. Copy and paste into the command in the Terminal window.

  This will remove all data from the fuser unit, then you had better be sure of your backups.

  Quit the Terminal, and then repair the Fusion drive (see "Troubleshooting" on the linked page.)

  Quit disk utility. Then you should be able to install OS X and restore your data from a backup in the main screen.

• a fusion drive is good for audio recording?

  I think buy a 27-inch iMac for audio recording on Logic Pro X, but is not sure a merger player performance, because some say that the part of the HARD of it on only 5400 RPM drive, if I hold with an iMac HARD 7200 RPM drive?

  You will likely get different opinions, but personally I would not use the fusion drive and recommend an SSD.

  Quite significant speed difference.

• fusion drive

  I just start up my iMac 27 "that I received in August 2016. I ordered a Fusion 1 TB drive. What is the profile of what it says. How will I know that's what I ordered? Somehow this iMac has no help.

  

  Go to Apple > about my Mac > system report > navigate the material, then click SATA. A regular reader will have an entry as well as the size shown below; a fusion player lists an SSD and a normal HARD drive. Mine has a HHD & SSD, but they have not been defined as a fusion drive:

  

  Then you should see a 1 TB HHD and then a 24 GB SSD hard drive (maybe 128)

• Help required with the MacMini Fusion Drive

  Hi all

  I recently bought a second hand end 2012 MacMini i7 wth a fusion drive. The previous owner had created a windows partition. I don't want to return the machine to its original out of the box factory for my use, as I did not need to run windows on it.

  I'm fighting to get the fusion drive to merge. Currently, I have two separate discs that I named her 329 and 781 GB. Disk utility shows that both drives are very good. I rebooted into Recovery Mode to use online disk utility and readers are not displayed in red, and so there is no option to fix them.

  I used the Terminal (after reading online) and it provides the following information:

  None of the data on disks is essential because it is broadcast on my old Mac mini and can be re-migrated later.

  Any advice on how to return the disc of the merger to its original state of the box please?

  Open Boot Camp Assistant and refer the reader to a single partition setup.

• Fusion drive how...?

  Hello

  The other day I saw a post with a link to a Web page on how to create your own Fusion player. In my view, that it may have been an Apple Web page.

  However, I forgot to bookmark.

  Basically, I have a Macbook Pro mid-2012 13 inch Non-retine compatible with having a third of road merger.

  I would like to know what hardware is recommended for the creation of a third party by car merger?

  (1) what hard drive model?

  (2) what SSD model?

  Also can you use boot camp with a third party by car merger?

  You can create more partitions on a drive of Fusion and install OS X, MS-Windows, Linux, etc...

  -Thank you

• Restore factory for 3 TB Fusion Drive settings

  I should just come here first, Apple phone support has been no help at all, took two officers to just make me an appointment at the Apple Store for tomorrow.  I'm sure they were also just guess what to do.

  I decided to format and restore my iMac with screen Retina 5 k, there is a merger of 3 TB drive.  I would just restore the drive to merge its factory settings which seems just a partition that includes the SSD & HDD together... I think that RAIDed... I'm not really sure, I've been googling and I am even more confused now.  I'm having the hardest time and whenever I try to delete a partition or delete something that I feel like I'm making it worse, which is why I called Apple, but they were not useful.

  Does anyone have any suggestions?  I have no other drive connected to my iMac.

  Is there maybe a terminal command to restore the unity of fusion to its original state so I can install El Capitan again?

  I've attached a picture of disk utility where I left with telephone support from Apple.

  

  N ° the SSD & HDD are not searched in a merger player. They linked together in a logical volume so that the data can be promoted and demoted to maintain the data that you use on the SSD and the data that you do not use the HARD disk. Giving you the SSD performance but a hard disk storage space.

  You will find indications to recreate your Fusion drive to the http://blog.macsales.com/15617-creating-your-own-fusion-drive

  I hope that you have a backup because only when you have completed this procedure the Fusion drive will be empty.

• How can I set up a fusion drive when my main drive is ssd?

  I have a new Mac Pro with a 500 GB internal ssd.  I want to implement a fusion drive using an external hard drive to 500 GB.  The discussions I've seen seem to be the reverse:

  an internal hard drive and an external ssd.

  Why you want to do this?

  I just use the disk SSD internal flash as a skinny bot player and put the data on the external hard drive

  Tip: Create a lean, fast boot disk

  In

  Mac mini (late 2012 and later versions), iMac (late 2012 and later versions): about of road Fusion - Apple Support

  Apple says:

  External hard drives USB, FireWire or love at first sight can be added to the Fusion drive?
  An external hard drive can be used as part of a Fusion drive volume. Merger drive is designed to operate with an internal hard drive and internal flash memory.

• Fusion drive vs 7200 RPM HARD drive, it is worth the difference in price?

  I have the beginning 2009 24 "clocked at 2.66 GHz, Intel Core 2 Duo w/4 GB memory.  I have 86 GB of capacity, 83 GB available on my hard drive but I get these days, turn the beach balls, delayed typing, and 5-6 min restarts (if it does not crash).

  (1): I started in recovery mode, run Disk Utility first aid on the three volumes that I configured and also to perform first aid on my external HD backup and time Machine external HD to ensure that those to external systems were functioning properly.  They are.

  (2) I ran Disk Warrior on all volumes and Cocktail on bootable disks.

  So... is probably time to let decision-making in early 2009 iMac.  Looking at the new, I wonder if the 27 "1 TB drive merger is worth the difference in price of the 1 TB 7200 RPM HARD drive?  I only do the usual things: mail, loading some photos (about 12 000 photos in iPhoto), web searches, etc.  No big, heavy use.

  It the additional sum of $200. Fusion drive worth it?

  For this purpose? N °

  Hello golden2,.

  I understand that you have a DVD picture in your SuperDrive drive, but it is not mount on the desktop and will not eject.

  Please, try the procedure described in this article using the disc is ejected.

  Get help with the SuperDrive slot on your Mac - Apple Support loading

  Do not eject discs or discs eject slowly

  1. If the drive ejects discs slowly or appears to have difficulty, insert and eject a disc several times. Check the disc to see if it has a label or other material stuck to the disc which increases the thickness. Remove the label if possible.
  2. If the disc does not eject, try pressing the eject on the keyboard button. Some older keyboards may use the F12 key to eject the disc.
  3. If the disc does not eject, try dragging the icon of the disk to the trash.
  4. If the disc will still not eject, try to hold down the mouse or trackpad button after you restart the computer. The Superdrive should attempt to eject the disc.
  5. If the disc still does not eject, reset the System Management Controller (SMC) and repeat steps 1 to 4.
  6. If the disc still does not eject, Contact Apple or an provider of services authorized Apple, or make an appointment with a Store Apple Store for further assistance.

  Take care.

• What are the specifications for a fusion drive

  I'm looking into getting a new mac mini and I think to get a player of fusion. I currently have a mini 2011 that I install with a SSD that is dedicated to the operating system and applications, and the original for data (documents, pictures, music) hard disk. Some can give me the specs for a merger for a new mini unit (2015)? I would like to know if the SSD is 3g or 6g, what is the size of the SSD, and what is the speed of the hard drive. I guess the size

  The SSD is based PCle blade, which is much faster than a SATA III/6 GB/s SSD.

  Note that the basic model has only a hard drive or drive of available fusion while the other two models also have a large PCle based SSD as an option in addition to the rotation of the road and road of fusion. The SSD n a fusion drive is about 120 GB

• Fusion drive: files on HDD or SSD?

  Hello

  I added an SSD for my iMac mid-2011 (12.2) and "merged" into a fusion drive. iMac, boots in 20 seconds, instead of 4 minutes or more. Safari, mail etc work very quickly, so drive merger works well. BUT for example InDesign CS 6 works always 'normally', so he has not transferred to the SSD, which (as I read on the internet) is supposed to happen with programs that are widely used.

  I've had the drive of fusion for 2 weeks now: whatever it is maybe wrong or I just wait the programs often used to switch the SSD? Is there someone who can shed some light on this?

  What do you mean by "merged"? You use CoreStorage commands to create a real fusion drive.
