Apple Workgroup Server

Apple Workgroup Server (AWS or sometimes WGS) and, later, Macintosh Server, are the names given to selected models of Macintosh computers which were sold by Apple Computer with additional server software and sometimes bigger hard drives. Apart from that, they were mostly identical to computers out of Apple's workstation range. The "Workgroup Server" name was used on the models based on Centris, Quadra and early Power Macintosh series, while the servers based on the Power Macintosh G3 and Power Mac G4 were called "Macintosh Server G3" and "Macintosh Server G4". The first model was the Workgroup Server 95, introduced in March 1993; the last of the series was quietly discontinued in January 2003, after the introduction of the Xserve made them obsolete.

The Workgroup Servers are not to be confused with the Apple Network Servers, which were specially designed servers that exclusively ran on AIX and thus do not qualify as Macintosh computers.
