The Macintosh IIvi (also sold as the Macintosh Performa 600) is a personal computer designed, manufactured, and sold by Apple Computer from September 1992 to February 1993.

The IIvi was introduced alongside the Macintosh IIvx, using a slower Motorola 68030 processor (16 MHz vs. 32 MHz) and no floating point unit or RAM cache.

[citation needed] It is the only model in the Macintosh II family to be branded as a Performa.

This model was discontinued four months after its introduction, when the Centris 650 was introduced at a similar price point.

[1] The Performa 600 models were formally introduced on September 14; shipments were delayed until October to coincide with the introduction of the IIvi and IIvx.
