Edit: Nevermind, I think I found the solution here. I have a rMBP with 16 GB of RAM which was causing me to have a 16 GB sleep image file. I decided I didn't want that much hard drive space wasted for a feature I'm not that interested in, so I opened up the terminal and entered these commands: sudo pmset -a hibernatemode 0 sudo rm /var/vm/sleepimage The sleep image file was erased and I was happy. My issue is that every time I put my laptop back to sleep, the sleep image file returns, even though I disabled safe sleep. I even checked in the terminal. When I input this command in the terminal: pmset -g | grep hibernatemode I get this result: hibernatemode 0 which seems to imply that safe sleep is in fact off... Does anyone know what may be causing this issue?
