How To Customize the Login Screen on OS X Yosemite
The login screen on Mac is pretty sleek and beautiful. But sometimes some of us might find it boring, but if you want to customize it, here’s a simple way to do it.
- save your desired image as: /Library/Caches/com.apple.desktop.admin.png.
- Then, just log out to apply the change.
Simple as that 😀
The best wallpapers tend to be justified to the right or left so the login fields aren’t covered up.
Another tip,brighter images work best because the login window dims them.
