"Appears to work well with Mountain Lion, March 26/13"
Used it for an hour. Ran pretty good. Gimp finally runs entirely on its own. Nothing else to download. Just start it up and it goes. Free. There is a big gap in the freebies between this app and low-end Seashore or whatever it's called, but Seashore is rather obtuse for a basic editor, so I'd rather put up with the complexity of GIMP, and work my simple way around the complexity for the basic needs.
Can't find many, except when I simply dragged an image file into a 'New' project, it crashed. Maybe you're not supposed to do that, or the image was too big for picture size or something, but I'm not a professional image worker. Once I opened the image from the file selector, it was fine
Good product, no extras needed anymore, Free.
