This is something we as graphic and web designers like to do and it’s quite easy to accomplish. There are two ways to change the icons in Mac OS X; the first is a simple copy and paste method and the second uses a nifty little program called CandyBar.
Copy and Paste Method
A simple way to change the icons in Mac OS X is to create your icon image in a program like Adobe Photoshop, save it somewhere and then go to that location in “Finder”, right click (cmd + click) and “Copy” the icon. Now, go to the folder that uses an icon you want to change, and right click (cmd + click) on the folder to be able to select “Get Info” from the pop up menu. Click the icon at the top left of this window and simply press cmd + v to paste it. Voila, new icon should now be in that top left icon area to show you that you completed the process correctly.
