Hi there fellow comrades, so here is the problem. I have 500GB SSD in my Mac and I decided to divide it in half so that I can use windows on the other half. Long story short I got a new windows laptop and don't need windows on my Mac anymore. I managed to delete bootcamp but I have no idea how to merge it back, on windows its so much easier By the way I'm running OSX HIGH SIERRA BETA Please help.
