Mac OS X 10.3 Panther

Released in October 2003, Mac OS X 10.3 Panther cut off “Old World ROM” Macs like the beige Power Mac G3s and some early PowerBook G3 models. Many users worked their way around this with third-party tools that would trick the installer.

For their work, users were rewarded with a streamlined version of OS X with a revamped Finder (now clad in Brushed Metal, sadly), Fast User Switching, Exposé for window management, FileVault, Font Book and iChat AV, among other features and updates, including built-in Fax support.
