I have a MacBook Pro, Mac OS X version 10.6.8. I downloaded both XQuartz and Gimp (Version for Snow Leopard/Lion, 2.8.0), logging out and then back in to ensure XQuartz would work. I transfer Gimp to my Applications folder and then double click to open it. It asks me if I really want to open it cause I got it from the internet and I say yes. It opens in my Dock, the little icon bouncing with the little dot beneath it. And then a couple seconds later it closes out and vanishes. It starts to open but then shuts itself down and I can't figure out why.
How come Gimp won't open even though I have XQuartz?
