The '''Macintosh Performa 6100''' is the consumer-oriented version of the [[Power Macintosh 6100|Power Macintosh 6100/60]], released on November 1, 1994. It is the base model of the Performa 6100 series without a CD-ROM drive, differing from the [[Macintosh Performa 6110CD|Performa 6110CD]] only in the absence of the optical drive.

The Performa 6100 was the first PowerPC-based Performa, representing Apple's transition from the Motorola 680x0 architecture to the PowerPC platform in the consumer market.<ref>{{cite web |url=https://everymac.com/systems/apple/mac_performa/specs/mac_performa_6110cd.html |title=Macintosh Performa 6110CD |publisher=EveryMac.com |access-date=2026-02-10}}</ref>
