Sometimes default things get old real fast. We look at them long enough and they start becoming eyesores. This also seems to happen with ever single design project I work on — I start out loving it, and by the time I’m finishing up — I hate it. It’s a disease, and I’m working through it.
One thing that really gets me annoyed is the default login wallpaper. I hated it when I was my default background, and I definitely hate it now that it’s in my face every time I log in.
Essentially we want to hit up /System/Library/CoreServices and replace DefaultDesktop.jpg with whatever your little heart desires. Word of caution, Back that thing up!
You’ll likely be asked to “authenticate”, and to put in your administrator password. So you might want to have those handy.
