I have GIMP on my Macbook. It was just as easy to install as any other downloaded app. I'm running Leopard with X11 (a requisite install for GIMP) already pre-installed, so IIRC, it was just a little drag and drop action with the .dmg installer.I went to check out GIMP for Mac, but I don't think it is too easy to install.
I also don't want to jeopardize baby pictures, for this thing.
If you're running Tiger, X11 may not be installed, but is located on your install disc that comes with a Mac. After X11 installation make sure you update it with the Mac Update tool. I think that's the only extra hoop Mac users need to jump through.
