    Hello All,

    I recently removed a partition from my Mac, it was used for the Yosemite beta, now that it is removed my original partition will not go back to full capacity of the HDD. The HDD is 750GB, now my main partition will only show 700GB. I cannot resize it, it will also not let me create a new partition when the 50GB extra. Please see the attached screenshots at the bottom of the pictures. I have tried reindexing the mac to no avail.

    Thanks for any assistance you can provide!
    Joe

    Run this in the terminal

    Code:
    diskutil list
    What is the output?

    Your partition is a logical volume group.
    Yosemite install does that with newer MBPros particularly.

    How to fix?
    You need to revert the partition.
    More info on this short thread.
