All versions of Mac OS X that were made to run on PowerPC systems (with the exception of Leopard) had a Mac OS 9 emulation layer called 'Classic'.

It started out on PowerPC processors but later transitioned onto Intel processors with Mac OS X Leopard (10.5) the last to natively support the PowerPC architecture and Snow Leopard (10.6) the last to support PowerPC applications on Intel-based Macs. It also adds the Dock as a place to launch applications (Not dissimilar to the underused Launcher) as well as some other features. It features a new theme called Aqua which replaces Platinum from Mac OS 8 and 9. It is based off the unix kernel and provides compatibility with X11. It is a conglomoration of NeXTSTEP, A/UX, and Mac OS 9.

Mac OS X is an operating system by Apple Inc. Terminal was used by Apple as a showcase for macOS graphics APIs in early advertising of Mac OS X, offering a range of custom font and coloring options, including transparent backgrounds.What is Mac OS X for PPC (OSX 10.0, 10.1, 10.2, 10.3, 10.4, 10.5)? These include the ability to use the standard macOS Help search function to find manual pages and integration with Spotlight.

Available options are ansi, dtterm, nsterm, rxvt, vt52, vt100, vt102, xterm, xterm-16color and xterm-256color, which differ from the OS X 10.5 (Leopard) choices by dropping the xterm-color and adding xterm-16color and xterm-256color. The preferences dialog for Terminal.app in OS X 10.8 (Mountain Lion) and later offers choices for values of the TERM environment variable. The user can choose other shells available with macOS, such as the KornShell, tcsh, and bash. Īs a terminal emulator, the application provides text-based access to the operating system, in contrast to the mostly graphical nature of the user experience of macOS, by providing a command-line interface to the operating system when used in conjunction with a Unix shell, such as zsh (the default shell in macOS Catalina ). Terminal originated in NeXTSTEP and OPENSTEP, the predecessor operating systems of macOS. Terminal ( Terminal.app) is the terminal emulator included in the macOS operating system by Apple.
