Gimp on Mac OS X

Gimp is a free drawing program with a slightly quirky user interface. The Mac version runs on X11 which is a window environment that is used on most non-Mac Unixes and results in it not being a “true” Mac application. It is still very useful, though. Tips:

• Snow Leopard has X11 installed by default, no need to do anything but download Gimp.app.
• Gimp shows its tool palette in a separate window where one always needs two clicks to make something happen (one to activate the window, one to do something). To fix: go to “X11 → Preferences → Windows”. You have two options:
• Click-through Inactive Windows: Performs window activation and an action with a single click.
• Focus Follows Mouse: Automatically activates the window under your mouse cursor.
