Here is how to change your normal app iCons
1. Open Terminal (/Applications/Utilities/

Then enter your password. After you did that, go to your application or file you want to replace your iCon with another one.

3. Open your new iCon in Preview. Make sure the Preview window is in the foreground and press Command + C.
4. Go to your application, and do Control + Click. Click “Get Info” in the menu.
5. When the “Get Info” window opens, click the iCon in the top left corner so there is a blue outline around it.
