I am doing some hard drive rearranging and I would like to give my mac install more space. Right now it has about 14 gigs and I would like to bump it up to about 50. I have tried gparted and gparted live. They give me the option to shrink the partition but I am unable to increase the size of it. I tried just shrinking one partition by 2 gigs but it still does not allow me to increase the size of the hsf+ partition.
