I am trying to repartition my hard drive back into an OS X only hard drive. I used disk utility to erase my bootcamp partition, but now I can't seem to find a way to add that empty space back to my OS X partition, to restore it as the only hard drive. I now found out that this isn't the proper way to repartition, and that I should've used the bootcamp assistant. The bootcamp assistant now says I have no partition when I try to follow the correct process. Is there any way to fix this? Thanks so much in advance.
