  Pure how to install OSX on a Fusion drive and keep the recovery disc function

  These instructions assume that your iMAC partitions or file systems has been damaged and you want to restore to the way most efficiency with fusion drive and the recovery partition, similar to what was built in the factory.

  These instructions work for the iMAC, retina 5K end 2014 version comes with OSX Yosemite. The scores of major drive of the 128 G SSD and 3 TB of HARD drive has been configured as a logical drive (merger by car).

  WARNING: These instructions here are shared for interest only. Readers to take their own risk by following these instructions. The author is not responsible for any damage caused by following these instructions.

  This is the target disk partitions, and the configuration that we want to achieve.

  Disk0 is the 128 GB SSD - solid state drive and holds the start of the partition (disk0s3)

  Disk1 is the 3.0 to HDD - mechanical transmission and holds the Recovery HD partition.

  There are two EFI partitions to partition table GUID on both hard drives (disk0s1, disk1s1).

  Disk space remaining (partition disk0s2 and disk1s2) are used to create the disc of Fusion 3.1 to named "Macintosh HD".

  Fusion unencrypted drive

  Here's how we do it.

  • A. clean reinstallation of Mac OS x.
  • 1. make sure that you back up all your data on the hard drive using Time Machine or other means. The following procedure will delete all data.
  • 2. create the OSX install USB, insert it to the MAC workstation.
  • 3. given that us will be operated on the internal trunk of the reader of the Mac, it must start on OSX install USB (see Y.).
  • 4. in the menu at the top of the screen, select disk utilities.
  • 5. turn highlighted the volume of disk Fusion called "Macintosh HD." Click clear to clean.
  • 6. If his success, then go ahead to install OSX new to that partition, as usual.
  • 7. otherwise, if it does not, that means fusion drive has been damaged.
  • 8 follow the instructions below to fix it.
  • . B. Split disc Fusion in the physical hard disks
  • 1. Since us will be operated on the internal drive of the Mac trunk, assumes that we already have boot up OSX install USB drive (see Y.).
  • 2. in the menu at the top of the screen, select utilities and Terminal.
  • 3. on the screen of the terminal type:
  • Cs diskutil list.
  • You will see something similar to the screen below.
  • 4 copy the long string after Logical Volume and replace the UUID with it in the following command to delete the logical volume of the disc fusion (aka coreStorage of logical volume):
  • diskutil deletevolume cs UUID
  • For example:
  • diskutil deletevolume E59B5A99-F8C1-461A-AE54-6EC11B095161 cs
  • 5 copy the long string after the logical volume group and replace the UUID with it in the following command to remove the drive (aka coreStorage) fusion:
  • diskutil cs remove UUID
  • p. ex. diskutil cs remove E03B3F30-6A1B-4DCD-9E14-5E927BC3F5DC
  • 6. at this stage, the fusion drive has been deleted, and hardsisk SSD and mechanical hard drive will be reappear in diskutil or separate records.
  • 7. If step 5 or 6 takes more than 30 minutes to complete, this means that the fusion drive has been corrupted. You can follow the commands below to clear the table to partition the hard way. First command clears the SSD drive, second command erases the HARD drive.
  • The command does not return a response, after 1 minute, press Ctrl + Z to complete orders. 1 minute is enough data to code and erase the partition table on the disk.
  • cat/etc/random >/dev/disk0
  • cat/etc/random >/dev/disk1
  • . C install a new copy of Mac OS x for the hard drive HDD and tested this disk partition hard recovery work.
  • 1. go on diskutil to create a partition called Macintosh HD HDD hard drive using all the space there.
  • 2 do the same with the mechanical hard drive.
  • 3. follow the usual procedure to boot from the installation of OSX USB and install a new copy of Mac OS x hard disk SSD.
  • 4. This will create the correct priming of the partitions, recovery hard drive partitions and PSX partitions hard disk HDD.
  • 5. once the installation is complete, test if OSX may start successfully, but no need to go through the initial MAC OS x didn't put in place that we're going to waste this and do the installation again later.
  • 6. we must now test if the recovery hard drive partition works.
  • 7. reboot for hard drive recovery (see X - by pressing command and R at the same time during boot right after that you hear sound start and release only a few seconds after you see the apple logo and the progress bar for loading...)
  • 8. it is important to test and make sure that the partition of hard drive recovery.
  • D. recreate the fusion drive
  • 1 since us will be operated on the internal trunk of the reader of the Mac, it must start on OSX install USB (see Y.).
  • 2. in the menu at the top of the screen, select utilities and Terminal.
  • 3
  . on the screen of the terminal type:
• diskutil list.
• You should find that we have a list of disk group hard physical volume only, no logic here still.
• 4. you will see something similar to the screen below.
• 5. search for the largest partition on the SSD hard drive, which should be close to the maximum size of HDD to the SSD (121 G, for example) and mark the name of the device, this will usually be something like/dev/disk0s2
• 6. search the largest disk partition mechanical forming fusion with the SSD hard drive. This should be close to the maximum size of the mechanical hard drive (for example 3 TB) hard disk and mark the name of the device, this will usually be something like/dev/disk1s2
• 7
. Now let's create the merger in car (group alias logical volume) in the Terminal, type: diskutil cs create nom_lecteur driveIDs
• The number of the driveIDs is unlimited, it may be a number of discs, or a number of disk partitions. Always put the faster discs first, for example for our SSD disk0s2
• For example:
• diskutil cs create fusiondrive disk0s2 disk1s2
• diskutil - the version of disk utility command line.
  cs - This calls for Core Storage, which is necessary for the merger.
  create - creates a basic storage group.
  nom_lecteur - is the name of the drive and how you want that he
• appear in the disk utility (not the Finder - that comes later). You can call it what you like; in our example, we named our Fusion table "Fusion".

driveIDs - Here is the Player IDs of the readers you want as part of your Fusion table, separated by a space. In our example, they are 'disk0' and 'disk1', but it may be different in your configuration.
• It is important that the faster hard drive appears first in the command, which in our case the disk0s2 (a partition in the SSD). In this way, drive fusion will use this disk as primary and the cache. The second disc in the command, in this case disk1s2 (a partition on the HARD disk). The secondary disk (HARD drive) is used to store less frequently used files.  Otherwise, the fusion drive performance will be worse that it is designed for.
• 8. you will see something like below appear on the screen:
• Creation Volume logical storage of kernel
• Move isk0s2 storage of carrots
• Disk1s2 of switching for the storage of carrots
• Waiting for logical volume group appear
• Discovered the new group of logical volumes 'DBFEB690-107B-4EA6-905B-2971D10F5B53 '.
• Store LVG UUID: DBFEB690-107B-4EA6-905B-2971D10F5B53
• Finished CoreStorage operation
• 9 copy to the bottom of the string after "Discovering new Volume Logic Group" using the command + C
• 10. next, create the partition of the merger (alias logical volume) drive named "Macintosh HD".
• In the Terminal, type: diskutil createVolume groupString jhfs cs + size volumeName
• For example:
• Diskutil createVolume DBFEB690-107B-4EA6-905B-2971D10F5B53 jhfs cs + 'Macintosh HD' 100%
• diskutil - once again, this is the version of disk utility command line.
• cs - called the basic storage functions, which are necessary for this arrangement.
• createVolume - this is the command to create the storage area real for the reader who is represented by an icon on your desktop.
• groupstring - this is the long alphanumeric string you copied in the previous step. It identifies the table you created such as getting a volume placed on it.
• jhfs + -the format of the disc. It is Apple (journaled) extended Format, which is recommended for drives with an operating system installed on it.
• VolumeName - the actual name of the volume, how it should appear under the icon. If there is a space in the name, you must put the full name in quotes ("name") or put a slash before the (name Drive\) space. In our example, we made these, naming our volume "Macintosh HD".
• size : this is the size of the volume. In our example, we had a 1.1 TB drive. We used '1100g' to describe what 1100 GB (1.1 TB to base 10). Otherwise, we could have also used 1.1 T or even 100% as a size.
• 11. go to diskutil to verify that you can see this new partition on the list.
• 12. test by erasing all the data from it.
• 13. then you can go ahead to start on the USB drive to install OSX and install a new copy of Mac OS x on it.
• 14. This will allow you to keep the recovery disk feature.
• X. how Prime to recover partition
• Press and hold the command and button R set immediately after hearing the bells to boot.
• Only release it 2 seconds after you see the Apple logo on the screen and the progress bar for the start. This will start the partition of hard drive recovery.
• Y. how-to boot OSX install USB
• Press and hold the command and the optionkey together immediately after hearing the ringing of boot.
• Only release it 2 seconds after you see the Apple logo on the screen and it will give you a list of startup disk choice, choose the OSX install USB to boot from.

• Ugggh.  I have a 27-inch iMac late 2011 and the hard drive was updated with a new SSD.  The integrated cd/dvd had to be taken out.  I then bought a thought of superdrive, it should work.  It's frozen on my iMac!

  Ugggh.  I have a 27-inch iMac late 2011 and the hard drive was updated with a new SSD.  The integrated cd/dvd had to be taken out.  I then bought a thought of superdrive, it should work.  It's frozen on my iMac!  Gee, who could have possibly guessed that would happen?  I tried all kinds of silly workarounds, I found on the internet, but still it will not register the stack of DVDs and other discs I have.

  If you're like me and upgraded your iMac that came with a cd/dvd drive internal... so he has to come out to give way to the fusion or the SSD drive, do NOT buy the apple superdrive.  It will work with your computer!

  Think I'll get a laptop samsung...

  Ironic, isn't it? Own Apple SuperDrive will not work with Apple computers. Shame you don't check here first that we would have warned you. Return Apple overpriced and buy a nice third-party player for a third of the price. I love the LG units. You can consider a loading plate because they are more reliable, and you can use these pesky disc when you get one.

• Can I put a Seagate FireCuda drive in my iMac late 2009?

  Apple Hardware Test (AHT) says that my SATA drive, 1 TB in size, has a problem.  Nothing specific indicated. The code given is: 4HDD/11 / 40000000:SATA (0,0)

  I was testing because of the prob trying to get a good download of macOS Sierra.  Looks like I need to replace a hard drive first.  I have an iMac late 2009 with a Core i7 quad core, 16 GB DDR3 1067 Mhz ram and ATI Radeon HD 4850 graphics card.  I can put a SSD in this unit or am I stuck with the Barracuda drives.  I'm looking for FireCuda readers and like what I see and read about them.

  If you want an SSD, then I highly recommend:

  • Samsung 840.
  • OCZ ARC100 and other models.
  • OWC 3 G SSD.

  The foregoing is all compatible and should work well. Your model only supports SATA 3 Gb/s speeds due to the controller, so don't waste your money on more expensive discs of 6 G or 6 Gbps because they work faster than a car of 3 G. If you decide on a 6 GB drive, however, they must be compatible as they work on the slower bus of 3G.

• iMac can't see SD cards

  My iMac can't see SD cards as before gradually.

  Disk utility cannot see the SD cards.

  All of my SD cards are good.  They can be read by other computers.

  Try a reboot.

  Make a backup using Time Machine or a cloning program, to ensure that data files can be recovered. Two backups are better than one.

  Try to set up another admin user account to see if the same problem persists. If back to my Mac is enabled in system preferences, the guest account will not work. The intention is to see if it is specific to an account or a system wide problem. This account can be deleted later.

  Isolate a problem by using a different user account

  If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.

• IMac late 2009 - 5 yellow bars on the screen - sometimes...

  Hi all..

  I recently bought an iMac late 2009 really nice second hand.  It worked wonderfully for a few weeks and I was about to become a mac convert.

  All of a sudden things have changed.  I pulled to the top of the machine first thing the morning only be greeted with lines to the bottom of the screen and a stall on a white screen.  The next day, it worked fine for a while.  Then the problem comes back for an hour or two.  Then back to yellow bars.

  I pulled up to my PC and started researching and found suggestions that this could be a graphics card problem.  After some time of reading and discovery, I pulled the top of AHT, and he advised me that there is actually a problem with the machine, and it's a sensor on the HARD drive.  Then, I would expect an additional error that could somehow link to the screen and absolutely nothing.

  Now, I know that historically the 27-inch late 2009 iMac screen / GPU has been examined by several different sites and forums but it is now an old machine and I don't know what to do.  What is a HARD drive failure?  Seems very unlikely but the only error listed... The flaw is GPU displayed on AHT down?  If this graphics card has received a "reformatting of oven" at a given time in its life and Ive been sold a dunce?

  Any advice would be great.  I don't have an Apple store near me and I don't know if they would even look at a machine this old.

  Help, please... My brief relationship was positive that ended quickly in tears!

• iMac (late 2009) 27-inch vertical streak on the right side

  iMac (late 2009) 27-inch vertical streak on the right side. Oddly enough it is still there even on the gray splash screen. How much is it? I tried restarts it, Vpram etc, but still there. Always in the same place. Is a graphics card out or the display itself. Should I make an appointment with an Apple Retail Store?

  Strange, strange! This mysterious line disappeared miraculously se today!

  I am delighted, but at a loss for why it appeared and why he disappeared.

  The only idea I have is THAT HEAT could have something to do with it.

  I look forward to any comments on this mystery.

• my 27 Imac late 2009 became very slow

  My 27 Imac late 2009 became very slow - I think especially after I've upgraded to El Capitan. Otherwise, everything in the computer works perfectly and I m using only 200 I have the 1 TB. Onyx and other tests can't find anything wrong. I mainly use my computer for word documents and to manage his photos about 30 000. The internal memory is 2 x 2 GB. Does anyone have any suggestions of what I could do to speed it up? Thank you.

  I wish I had an answer, but all I can do is rather echo to your problem. I have a 19 mid-2007 "iMac, contributed to the maximum with the RAM, 1 t disc hard less that half full, who did the same thing - he has worked with El Capitan until I updated to the latest version. Once that has happened the machine became so slow as to be unusable. It would take ten or twelve minutes to record a mouse click. When I restarted the machine, it took 32 HOURS to start (Fortunately it isn't my main Mac production).

  Last week, I tried all the remedies of common sense - by removing unused software, keeping an eye on the activity monitor (there is nothing fancy here), etc. Finally, I did all the stuff start, PRAM, run utilities disk (no noted problem) and even tried to reinstall El Capitan to a bootable USB I did with my first Mac, the reinstall, but seemed not 'take' somehow - he wanted to repeat the installation procedure again and again.

  I use the little Mac for Internet, e-mail and (as Karlis2) deal with some of the oldest pictures in my files - I'm sure that I have pictures on Time Machine, so I'm not too worried about it, but this was the first Mac way back in the day, I bought with my money and I'm a little sentimental on and would like to resurrect if possible... I wonder if there is a way to restore the operating system to an earlier version and it would make a difference?

• How to eject my iphone, or player card on my macbook air?  I don't want to disconnect and lose data...

  How to eject my iphone, or player card on my macbook air?  I don't want to disconnect and lose data...

  You won't lose data when you remove an iPhone, unless you're in the middle of the backup or synchronization of the device.

  If you see no activity in iTunes/Photos/etc... Then, it is safe to unplug.

  With a card reader (SD card?) you do drag the desktop icon to the trash. It turns into an arrow when you drag an icon ejector.

  Similarly, you can click Finder on the dock, then locate the reader on the left column and click on the "arrow" to the right of the device to eject it.

• Mid-2009 MBP memory is compatible with the iMac late 2009?

  Hello

  I just upgraded the memory for my MacBook Pro (from 2 X 2 GB 2 X 4 GB)... I was going to sell the used memory space but realized that I might be able to add to my iMac late 2009.  How will I know if it's compatible?  Currently the iMac only has 4 GB as 2 units but is expandable to 16 GB and has 4 slots available.

  Forward a response and thanks in advance.

• Connect a monitor 2nd or 3rd in 21 "iMac mid-2014

  Hello

  I work from home with sheets of Excel spreadsheets and Word documents.

  1. How can I connect a monitor 2nd or 3rd in 21 "iMac mid-2014?

  2. who monitors are not suitable?

  Thank you.

  iMac (21.5 inch, mid-2014), OS X El Capitan (10.11.4), 1.4 GHz Intel Core i5, 8 GB 1600 MHz DDR3.

  (1) use connections Thunderbolt or mini-DisplayPort. If necessary a mini-DisplayPort to HDMI or mini-DisplayPort to DVI adapter can be used.

  (2) according to the everymac each thunderbolt connection supports up to a 2560 x 1600 screen. Bonus points for a monitor with wide-angle IPS display technology and one case of white/silver to aesthetically match the iMac. Be aware that the iMac screen starts a few inches higher than the norm, so if you want your poster to the line up horizontally you'll be requires a monitor with a lot of height adjustment or a willingness to place the monitor on top a raiser, books or other items.
