It’s your image editor of choice. You’ve upgraded to Leopard. And The Gimp no longer works for you. You can try some of the suggestions found here, or you can just download AquaGimp. Note: I can only confirm AquaGimp works on an Intel based Mac.
With any luck The Gimp will be working in all of it’s X11 glory soon, and this tutorial will become moot.
If you go the AquaGimp route (which is what I’ve resorted to for the time being) continue reading for some tips on a few ‘quirks’ I’ve discovered so far.

- If it seems to ‘hang’ while starting up, just click inside the load-menu a few times. Don’t ask me…
- When you try to change numbers via the keyboard (instead of a slider etc) or pretty much anything that involves keyboard input, hold down the key on your keyboard. Then it’ll start. Very annoying when you’re trying to save a file with a different name.
- If you use the Hide feature (Apple Key + H) click the gimp 2.4 icon in your dock, not the actual Gimp icon, to bring The Gimp back into focus.
- Don’t even bother to right-click the Gimp icon in your dock. It always appears to be in a state of “not responding” even when The Gimp itself is responsive.
