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, AFP and SMB servers, an LDAP 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, wiki 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.
macOS Server is based on an open source foundation called Darwin and uses open industry standards and protocols. It included services and applications for file sharing, sharing contact information and calendars, schedule events, send secure instant messages, conduct live video conferences, send and receive email, contribute to and comment in wikis, publish a company-wide blog, produce and distribute podcasts, and set up websites.
Mac OS X Server 1.0 (Rhapsody)Edit
The first version of Mac OS X was Mac OS X Server 1.0. Mac OS X Server 1.0 – 1.2v3 were based on Rhapsody, a hybrid of OPENSTEP from NeXT Computer and Mac OS 8.5.1. The GUI looked like a mixture of Mac OS 8's Platinum appearance with OPENSTEP's NeXT-based interface. It included a runtime layer called Blue Box for running legacy Mac OS-based applications within a separate window. 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. Apple File Services, Macintosh Manager, QuickTime Streaming Server, WebObjects, and NetBoot were included with Mac OS X Server 1.0 – 1.2v3. It could not use FireWire devices.

However, a few months later, the company said it would instead sell the server components as a US$49.99 add-on to Lion, distributed through the Mac App Store (as well as Lion itself). The combined cost of an upgrade to Lion and the purchase of the OS X Server add-on, which costs approximately US$50, was nonetheless significantly lower than the retail cost of Snow Leopard Server (US$499).
