Most people know that when you want to remove an app from your dock, you simply need to right click it then drag it to the desktop. The first few times it disappeared in a puff of “smoke” you probably thought it was cool but if you’re over it now, it’s possible to change that “poof” to a twirl, fade, or anything else that strikes your fancy.
First, locate the file that contains the animation. Navigate to
/System/Library/Core Services. Hold down the control key, then click
Dock and choose
Show Package Contents. When the Dock window opens, select
Contents > Resources.
Locate the file called
poof.png and click to open. Gasp in surprise when you find out that it’s really just a five-frame graphic that can easily be replaced with your own file.
Use Photoshop, Seashore, Comic Life, or the image editor of your choice to create a cool new graphic that, like the existing file, measures 640 pixels tall. Then just save the new file and restart your system.
Poof, now you have yourself a new dock animation!
