expand partition in osx 10.11

[AndiChristiansen]

hi i have deleted my bootcamp partition and tried to expand my osx partition, but everything i do seem to fail or i not possible.. i have tried booting up in recovery but still nothing...

funny thing is, it seems to allow me to press the "-" on my osx system partition i am booted from, but the free partition i cannot pres the "-" to remove it and expand my osx partition...

Any ideas??

Open Terminal and at the command line run each of the two commands below then post up the output of each command. This will show the partition layout and I'll try and help you.

From the output, tell me which partition you want to keep/enlarge so I know what to do next.

diskutil list

diskutil cs list

Okay... it looks like either your Yosemite or El Capitan install converted the drive into a core storage volume, and those cannot be resized while in that format. Backup first just to be safe, but this should not erase your data. Go to Terminal again and enter the command below to revert (undo) the core storage volume and wait for it to complete. Then you should be able to resize the drive normally.

diskutil cs revert /
