What is MachTen?
MachTen is a Berkeley UNIX operating system with a Carnegie-Mellon Mach kernel. It runs as an application on the Macintosh Operating System (MacOS). The MachTen UNIX kernel supports a standard UNIX applications environment which in turn supports hundreds of standard UNIX applications. The UNIX operating system runs in concert with the Macintosh operating system. When MachTen is running, you still have access to the Macintosh Finder desktop and Macintosh applications, such as a Macintosh spreadsheet or desk accessory application. Even though MachTen gives the appearance of being just another Macintosh application, its operation is more like that of a co-resident operating system. MachTen and MacOS share the processor — when MachTen has control, it pre-emptively multitasks the UNIX applications; when MacOS has control, it runs the Mac applications using its cooperative sharing. Since MachTen runs on top of MacOS, there is no need to partition the hard drive or to install separate MachTe
