MacOS Server

macOS Server, formerly Mac OS X Server and OS X Server, is the server edition of Mac OS X developed by Apple Inc. It is based on the BSD-Unix derived operating system Apple Computer that acquired from NeXT to form the basis of AppleShare services provided server applications such as file and printer sharing and user management.

Product history
The first version of Mac OS X Server, released on March 16, 1999 and dubbed "1.0" was a hybrid of OPENSTEP from NeXT Computer and Mac OS 8.6. The GUI looked more like OPENSTEP did, with an emulation layer for running legacy Mac OS 8.6 based applications. WebObjects was included with the server package.

Beginning with version 10.0 of Mac OS X Server released May 21, 2001, the server version and the standard version are nearly identical. Mac OS X Server mainly adds server management software&mdash;web, mail, and user services. Most of OS X Server's services are based on standard BSD tools, e.g., the Apache web server; Mac OS X Server adds a GUI interface to these services. An exception, however, are User services, which are based on (NeXT's) NetInfo.

Version 10.3 (released August 2003) of OS X Server presented a mature, fully featured server environment. User and file management are provided via Open Directory, an LDAP compatible server architecture. The new Workgroup Manager interface improves configuration significantly. Many common network services are provided such as NTP, SNMP, Web Server, Mail Server, LDAP, AppleTalk, Print Server. The inclusion of SAMBA version 3 allows tight integration with Windows clients and servers. MySQL v4.0.16 and PHP v4.3.7 are also included.

Starting with version 10.7, OS X Server became available as a downloadable update to Mac OS X, adding extra server features lacking in the Client version of the OS. This is mostly the configuration interface, as the back-end services mostly included in OS X proper.

It is important to note that each point release of Server is its own product. Unlike the client OS, a network needs to standardize on a single 1.x/10.x version of Server, as the different versions are not completely interoperable via the networked management interface. This is especially the case after 10.7, where the computer requires the appropriate base 10.x installation before the Server package can be purchased and added to it.
