macOS Server, formerly Mac OS X Server and OS X Server, is a separately sold operating system add-on which provides additional server programs along with management and administration tools for macOS.
Prior to version 10.7 (Lion), Mac OS X Server was a separate but similar Unix server operating system from Apple Inc. architecturally identical to its desktop counterpart Mac OS X. With the release of version 10.7 (Lion), Mac OS X and Mac OS X Server were combined into one release. A separate "server" operating system is no longer sold; the server-specific server applications and work group management and administration software tools from Mac OS X Server are now offered as macOS Server, an add-on package for macOS sold through the Mac App Store along with Workgroup Manager 10.8, available from the Apple support web site.
These tools simplify access to key network services, including a mail transfer agent, and SMB servers, an server, a domain name server, and others. Also included (particularly in later versions) are numerous additional services and the tools to manage them, such as web server, server, chat server, calendar server, and many others.
Mac OS X Server was provided as the operating system for Xserve computers, rack mounted server computers designed by Apple. Also, it was optionally pre-installed on the Mac Mini and Mac Pro and was sold separately for use on any Macintosh computer meeting its minimum requirements.
