Terminal (Terminal.app) is the terminal emulator included in the macOSoperating system by Apple.^[1] Terminal originated in NeXTSTEP and OPENSTEP, the predecessor operating systems of macOS.^[2]

As 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^[3]).^[4] The user can choose other shells available with macOS, such as the Korn shell, tcsh, and bash.^[4][5]

The preferences dialog for Terminal.app in OS X 10.8 (Mountain Lion) and later offers choices for values of the TERM environment variable. 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. These settings do not alter the operation of Terminal, and the xterm settings do not match the behavior of xterm.^[6]

Terminal includes several features that specifically access macOS APIs and features. These include the ability to use the standard macOS Help search function to find manual pages and integration with Spotlight.^{[citation needed]} Terminal was used by Apple as a showcase for macOS graphics APIs in early advertising of Mac OS X,^{[citation needed]} offering a range of custom font and coloring options, including transparent backgrounds.

Here is a short guide on how to build QEMU to run Mac OS 9 with working audio. These instructions work for MacOS High Sierra as the host OS, although with some tweaking they may run under Linux/Windows. You should be comfortable compiling software from source before attempting.

Clone QEMU fork

Adapted from instructions from Cat_7

You may need to install XCode and/or the XCode command line tools. If you do not have them, then this process may prompt you to install them (MacOS will do that).

Start by cloning the fork of QEMU with experimental audio support:

Then configure the source to use MacOS CoreAudio. I have also enabled LibUSB, KVM, HyperVirtualization Framework, and the Cocoa UI. In this case I am only compiling the emulator for PPC (32-bit).

Then compile:

This will create a binary in qemu-screamer/ppc-softmmu/qemu-system-ppc that we can use.

Create HD for Mac OS 9

We will need to have a hard drive image for our emulated system. I made mine 5 GB in size, which is plenty for Mac OS 9.

In our qemu-screamer directory, we will use qemu-img to create the disk image.

Get a Mac OS 9 Installer

If you have an ISO of a Mac OS 9 install disc (a Mac OS X classic install disc won't work), then you can use that in the next step. If you don't have one, you can download one from Mac OS 9 Lives: Mac OS 9.2.2 Universal Install.

Install Mac OS 9

This won't install quite like Mac OS 9 did, but instead use Apple System Restore to restore an image onto the hard drive.

Start up QEMU with the following options:

A breakdown of that command:

• -L qemu-screamer/pc-bios sets the BIOS. May not actually need this.
• -cpu 'g4' emulate a G4 CPU
• -M mac99,via=pmu will define the Mac model and enable USB support
• -m 512 use 512 MB of RAM, could go lower probably
• -hda macos92.img use our generated disk image for the hard drive
• -cdrom '~/Downloads/Mac OS 9.2.2 Universal Install.iso' use the ISO for the cdrom
• -boot d boot from the disk drive
• -g 1024x768x32 default to 1024x768 resolution and 32 bit colour

Once it starts up, you will be able to run Disk Initializer to format your hard drive image. Go ahead and do that, using Mac OS HFS Extended as the file system. One partition is good.

After initializing the disk, run Apple System Restore with the Mac OS 9 lives disk image as the source and your disk as the destination. This will take a minute to restore. Once done, shut down the emulated system.

Boot Mac OS 9

Similar to the last command, except we start up from the disk we created.

It should boot up and you will have a running Mac OS 9 with audio! Usb xtaf xplorer download for mac.

Tips

When the emulator is shut down, just make a copy of the hard disk image to create a backup. If something breaks your Mac OS 9 installation then you can restore the file.

You can dynamically attach CDs/DVDs to the emulated system by going to the menu bar on your host system for the QEMU application and selecting the option to attach to the CD IDE drive. It will open a dialog letting you select your ISO.
