Hey everyone, I have a mid 2014 MBP 15 inch, it has the 512 GB SSD in it, and i'm trying to clear some space off of it so I can dual boot more easily with plenty of space on my windows partition. I just deleted ~100GB from my HD, but the free space didn't go up at all. In the about this mac tab I now have 160GB of 'other' taken up. I deleted a few 1 GB files individually, and it didn't clear up the space at all in disk utility. I went into erase to erase free space on my HD and that was greyed out. How can I clear the deleted info off of my HD for real? It seems like it's simply making the information inaccessible for some reason. Very frustrating. Also i'm on 10.9.5.
