I want to multiboot my MacBook Pro, I'm trying to make partitions but in Disk Utility I can't make my partitions, only can divide by 2? Why? It's a normal SSD not a fusion drive (SSD+HD).

Now I'm fresh installing my Mac with internet recovery... (Second time) but this time in Disk Utility by internet recovery instead click on erase I clicked in partitions and make a partition named Macintosh HD.

What I'm doing wrong?

  • Is it a Core Storage Volume [Logical Volume Group]? That info would show at bottom left in Disk Utility. If so, see apple.stackexchange.com/questions/154964/…

  • I can't know now but in 2014 I already made more than 2 partitions. I don't know why disk utility don't let me partition the disk now, something I do wrong? Commented Jan 18, 2015 at 11:08
  • depends entirely on whether it's core storage or not

1 Answer 1


To be able to create a multi-boot environment you have to revert from a CoreStorage partition layout to a standard partition layout.

  1. Start to internet recovery mode by pressing altcmdR while booting.
  2. Open Terminal.app in the menubar Utilities → Terminal
  3. enter diskutil cs revert LVUUID and hit the key.
    (LVUUID is the Logical Volume UUID. You get it by entering diskutil cs list in Terminal.app)
    In your case it's diskutil cs revert 36635140-167F-4638-BF3C-4477ADAA6B21.
    If your CoreStorage Volume is tagged as 'revertible' this command should convert your CoreStorage volume to a standard volume non-destructively.
  4. Enter 'exit' when the conversion is finished and quit Terminal.app.
  5. Open Disk Utility and partition your SSD as you need.

    Thanks it worked.... Thank you very much.... By the way is there a editor to publish in stack exchange? How do you type/write the keys and how you make new lines without using br tag. Thanks again Commented Jan 18, 2015 at 16:44

  • @DiogoSaraiva BTW It's gonna be hard to create a 5-systems-boot environment. I don't know if it's even possible. Maybe you should consider VMware or Parallels...

  • FWIW, I've got a MB with 10.6 thru 10.10 all installed, as well as another partition with the 10.6 installer disk. Option-booting, with all the recovery partitions etc, is a screen full of hdd icons.
