The Macintosh Portable is a portable computer that was designed, manufactured, and sold by Apple Computer, Inc. from September 1989 to October 1991. It is the first battery-powered Macintosh, which garnered significant excitement from critics, but sales to customers were quite low.^[1] It featured a fast, sharp, and expensive monochrome active-matrix LCD screen in a hinged design that covered the keyboard when the machine was not in use. The Portable was one of the early consumer laptops to employ an active-matrix panel—only the most expensive of the initial PowerBook line, the PowerBook 170, had such a panel. The machine was designed to deliver high performance, at the cost of increased price and weight. The Portable was discontinued in October 1991.

The Macintosh Portable can run Macintosh System 6.0.4 through System 7.5.5.^[2]
