View Full Version : Installed 10.8 by creating a partition, Disk Utility wont give me back free space

I had an issue installing 10.8 on my 2010 mac so I followed the steps given here:


After I successfully installed ML, I tried to get my space back. [space left from deleting bootcamp partition]. However, Disk Utility gives me a few errors:

When I try to verify the hard drive:

MY current hard drive partition set up:

When I try to erase Untitled partition:

Notice how my Macintosh HD is not taking up the entire space at the bottom, if I try to take back that space nothing happens. Any help would be appreciated. :(

Hi yogarcia,

I'm having the exact same issue. Deleted a Bootcamp partition and now my 'freespace' has been stuck in some void. I'm currently unable to make a new partition or even merge it back to my primary partition. When I attempt to OSX claims it is being used for CoreStorage and must be adjusted using 'diskutil' in Terminal. Unfortunately, it's not even showing up at all in there...


I was disappointed to see that no one replied to your post. Were you able to find a solution? If not I think I'll need to schedule a Genius appointment.

It seems that I shouldn't have upgraded to OSX 10.8 so soon. There appears to be lots of wacky disk issues with it as it also broke one of my Time Machine external drives. I had to use a linux computer just to make the drive readable again by OSX.

Did you use the Boot Camp utility to remove the boot camp partition?

The Boot Camp utility locked up after eight hours after selecting remove. After opening disk utility, there appeared to be no change. So to answer your question, no. I used disk utility to erase the volume which generated errors. Any subsequent attempts give me the issue I posted above.
