    I just bought a brand new mid 2015 MacBook Pro with a 1TB drive. I just started using it today and have barely done anything on it yet. I have attempted to partition the drive in half using Disk Utility. How long should this normally take? It has been almost an hour and it seems to have hung. As I said, I have barely done anything to this new computer yet and this is one of the very first tasks I have attempted. Disk Utility has hung with the following messages: "Applying changes to Apple SSD" and in the details: "Initialized /dev/rdisk0s4 as a 465 GB case-insensitive HFS Plus volume with a 40960k journal". Nothing has changed in almost an hour. Is this normal or is something wrong? If so, how can I fix it without ruining the system? Also, I set up the original drive to be encrypted, but when partitioning I selected unencrypted for the new partition. Would that affect anything?

    Partitioning a disk with data on it can indeed take a bit more time, particularly if it involves shrinking a CoreStorage volume as in your case.

    Adding a second partition like you did should only take a minute or so.

    Just to clarify here... did you shrink the original, single partition down to 500GB then encrypt it... then now you are adding a second ~500GB partition? Otherwise, this will not work.

    Looks like something went wrong the first time. I erased the entire drive, reinstalled osx, set up everything exactly the way I did the first time, and attempted to partition the drive again the exact same way. It took less than a minute.
