The '''Macintosh Performa 450''' is a consumer-oriented personal computer introduced by Apple Computer on April 12, 1993.<ref>{{cite web |url=https://everymac.com/systems/apple/mac_performa/specs/mac_performa_450.html |title=Macintosh Performa 450 Specs |publisher=EveryMac.com |access-date=2026-02-10}}</ref> It is a rebrand of the [[Macintosh LC III|LC III]] for the consumer market, featuring the same hardware in the compact "pizza box" LC enclosure.

The Performa 450 was a significant upgrade from the earlier Performa 400-series models. It uses a Motorola 68030 processor running at 25 MHz with a full 32-bit data path. It shipped with 4 MB of RAM (expandable to 36 MB using a single 72-pin SIMM), 512 KB of VRAM (expandable to 768 KB), and a 120 MB SCSI hard drive.
