Support was added for RAID 0 and RAID 1 storage configurations, and Mac OS 9.2.1 in NetBoot. Mac OS X Server 10.1 (released September 25, 2001) featured improved performance, increased system stability, and decreased file transfer times compared to Mac OS X Server 10.0. Mac OS X Server 10.0 (released May 21, 2001) included the new Aqua user interface, Apache, PHP, MySQL, Tomcat, WebDAV support, Macintosh Manager, and NetBoot. The last release is Mac OS X Server 1.2v3. Apple File Services, Macintosh Manager, QuickTime Streaming Server, WebObjects, and NetBoot were included with Mac OS X Server 1.0. There was discussion of implementing a 'transparent blue box' which would intermix Mac OS applications with those written for Rhapsody's Yellow Box environment, but this would not happen until Mac OS X's Classic environment.

It included a runtime layer called Blue Box for running legacy Mac OS-based applications within a separate window. The GUI looked like a mixture of Mac OS 8's Platinum appearance with OPENSTEP's NeXT-based interface. Mac OS X Server 1.0 was based on Rhapsody, a hybrid of OPENSTEP from NeXT Computer and Mac OS 8.5.1. Mac OS X Server 1.0 was released in March 1999, predating the release of the consumer version of Mac OS X by two years. The Server app was discontinued on April 21, 2022, and Apple said that later versions of macOS would drop support for it. The Server app lacked many features from Mac OS X Server, and later versions of the app only included functionality related to user and group management, Xsan, and mobile device management through profiles. Starting with OS X Lion, Apple stopped selling a standalone server operating system, instead releasing an add-on Server app marketed as OS X Server (and later macOS Server), which was sold through the Mac App Store. It provided server functionality and system administration tools, and tools to manage both macOS-based computers and iOS-based devices, network services such as a mail transfer agent, AFP and SMB servers, an LDAP server, and a domain name server, as well as server applications including a Web server, database, and calendar server. Mac OS X Server is a discontinued series of Unix-like server operating systems developed by Apple Inc.
