Can someone help me with changing the desktop icons? I've downloaded some icons. Actually i wan to change the macintosh hdd icon to a mac mini one. some website gave these intructions but its not workin for me. Here is a step-by-step guide for setting a folder icon: 1) Select a file or folder that has the icon you want to use. 2) Press Command-I to bring up the Inspector panel. 3) Click on the icon once. You should see a gray border around the icon. 4) Press Command-C to copy the icon. Do NOT close the inspector panel. 5) Select the file or folder that you want to customize. 6) Press Command-V to paste the icon.
