Apple Mac OS X 10.3.5

It adds a completely new Finder that provides a vastly improved view of the system, with one-click access to your favorite files and folders, whether on your hard drive, iDisk, network servers or removable media.

Panther introduces the most revolutionary advance in productivity for a desktop windowing system in years. It's called Exposé?. With advanced virtual and protected memory, Mac OS X lets you have scads of applications open at the same time without fearing data loss in other apps if an unruly program crashes. And with several documents open per application, you could end up with dozens of open windows. Finding a window you worked on an hour ago can become a challenge. Exposé? lets you instantly see all your open windows at once, then switch to the right one. Or see just the windows of the current program. Or the files on your desktop. And you won?t find it anywhere else.

Fast User Switching makes it even easier to share your system with other people. You can let them log into your Mac without quitting any of your applications. Then with one click, you can switch back to your desktop with all documents and applications exactly as you left them. Panther uses an elegant 3D transition to move between user accounts.
