Visage Login allows you to easily and safely customize your Mac OS X login screen. Visage keeps track of Apple's default settings for every customization, so you can easily switch back to the original settings at any time.
You can add custom images, add a text message, add an Acceptable Use Policy and change the host information displayed. The host information can display the current date and time, Directory Services (network accounts) status, IP address, system version, host name, and more.
If you need to customize the Mac OS X login window, Visage Login is an essential tool!
