So I just partitioned the hard drive in my MacBook Pro 5,5 and successfully installed Ubuntu (12.04) alongside OS X. During the partition process I guess Disk Utility decided to allocate the majority of the free space (~51GB) even though I specified only 20.
This is really just a learning experience/experimentation and I don't need a lot of space for Ubuntu, so when installing I chose to give it about 20GB (of the 51) to play with. Now I have this remainder of the partition that isn't being used.
My question is can I reassign that space to OS X without disturbing anything?
