Q: This becomes useless with El Capitan's Disk Utility.

You can't see that partition, because there's no way to make it visible.

 

Apart from that, partitioning in El Capitan's Disk Utility simply does NOT work.

 

Removing, resizing partitions will always result in a mess. It never does what one wants to do.

 

Off-topic:

Has anyone tried adding a new partition to a disk that has a desired size which you type into the size-field?

 

Has anyone tried doing so by adding TWO new partitions to a disk, specifying their exact sizes?

 

That stupid pie chart will always open up addidional slices that were never meant to be created.

 

Many times it will not even do its job, returning only error messages, and my iMac's 3 TB Fusion Drive is shown as two Macintosh HD partitions of each 2,8 TB

 

and one Windows partition of 313 GB. Why??? There's no TWO 2,8 TB HFS partitions. How's that even possible on a 3 TB Fusion Drive?

 

Back to the original topic: Furthermore, you can't do what this article tells you if Windows creates a hidden Recovery Partition that later on the Boot Camp Assistant doesn't like. You're STUCK. Unless you have the option to either use the Yosemite Disk Utility OR are a master of the command line.

IMAC (RETINA 5K, 27-INCH, MID 2015), OS X El Capitan (10.11.3)

    Is there a specific problem you want to solve?

     

    Command diskutil is much better if you need finer control than DU (Yosemite or El Capitan). I have stayed away from ElC on critical Macs, because of such issues.

     

    The reason you see two CS volumes, is due to the partitioning is done for Windows on a 3TB Fusion drive. In OS X Terminal, run

     

    diskutil list

    diskutil cs list

     

    to see the partitioning layout of your internal disks.

    No, that's not it.

    See the video I've uploaded.

    Then you'll see what I mean.

    For the operations you want finer control on, use diskutil CLI.  The UI is not something I am a big fan of. Some issues of display can be resolved using SMC/NVRAM Reset.

     

    For the CS volumes, I have tested some of the verbs and played with them - OSX and Bootcamp discussion . In some cases, there is no equivalent option in DU on any version. For example, creating a second LV from the CS is unsupported in DU.
