    Good day.

    My hard drive used to have 3 partitions (one for ML, another for Mavericks and a Boot Camp).
    So now, I have removed the Mavericks partition and am trying to get Macintosh HD (the ML partition) to recover the disk space that was once occupied by Mavericks.

    Attached is a screenshot.

    Whenever I drag down the slider of the Macintosh HD all the way to the bottom and click Apply, it would revert back to what's in the screenshot after a message saying Partitioning Complete showed up.

    This is driving me nuts.

    Any ideas?

    EDIT: Repairing and verifying disk didn't help either.

    What happens if you choose 1 partition in the Partition Layout? Can you adjust the size then?
