If you are using Mac OS X 10.5 Leopard and want to change the look of your dock, try out Dock Library. It’s very simple to use and makes changes to the appearance of your dock very easy. And the best part, it’s free! I’m sure the creator, Pete Callaway, wouldn’t mind a donation though if you can spare it.
Download Dock Library for free along with the styles you want, then its just a matter of opening it up, importing the zip file from the custom style and then setting it as the dock. When you hit set you will have to enter your administrator password and there you go. Your new dock is there, piece of cake.
My dock is even shinier now, this is a great application and is very easy to use. It doesn’t require any hunting through system files or anything like that. If you want to go back to the default dock, it is listed with all of your custom ones and all you have to do is set it as the dock again. Simple. So if you are into customizing your Mac’s appearance, try it out, completely free!
