'''Mac OS&nbsp;X Server''' is a series of [[Discontinued software|discontinued]] [[Unix]]-like server [[operating systems]] developed by [[Apple Inc.]], based on [[macOS]]. It provided server functionality and system administration tools, and tools to manage both macOS-based computers and [[iOS]]-based devices, [[network service]]s such as a [[message transfer agent|mail transfer agent]], [[Apple Filing Protocol|AFP]] and [[Server Message Block|SMB]] servers, an [[Lightweight Directory Access Protocol|LDAP]] server, and a [[Domain Name System|domain name server]], as well as server applications including a [[Web server]], [[database]], and [[Calendar (Apple)|calendar]] server.<ref>{{cite web|url=https://www.apple.com/server/macosx/technology/unix.html|title=Mac OS X Server Snow Leopard - UNIX|publisher=Apple|archive-url=https://web.archive.org/web/20110609032125/http://www.apple.com/server/macosx/technology/unix.html |archive-date=June 9, 2011|access-date=November 25, 2012}}</ref>

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]].<ref name="server-specs">{{cite web|url=https://www.apple.com/macos/server/specs/|title=Apple - macOS Server - Read the technical specifications.|publisher=Apple Inc.|access-date=November 2, 2016|archive-url=https://web.archive.org/web/20161114180555/https://www.apple.com/macos/server/specs/|archive-date=November 14, 2016|url-status=dead}}</ref><ref>{{cite web|url=http://support.apple.com/kb/HT1822?viewlocale=en_US&locale=en_US|title=OS X Server: Admin tools compatibility information|publisher=Apple Inc.|date=July 25, 2012|access-date=October 21, 2013}}</ref> 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. The Server app was discontinued on April 21, 2022, and Apple said that later versions of macOS would drop support for it.<ref name="about-5.7.1-and-later" />

==History==
{{see also|macOS version history}}
[[File:OSXServerBoxes.png|thumbnail|right|400px|Box artwork for Mac OS X Server versions 10.1–10.6]]

Mac OS X Server is based on an [[open source]] foundation called [[Darwin (operating system)|Darwin]] and uses open industry standards and protocols. Mac OS X Server was provided as the operating system for [[Xserve]] computers, and [[rack unit|rack-mounted]] [[server (computing)|server computer]]s designed by Apple. It was optionally [[pre-installed software|pre-installed]] on the [[Mac Mini]] and [[Mac Pro]] and was sold separately for use on any [[Macintosh]] computer meeting its minimum requirements.

===Mac OS X Server 1.0 (Rhapsody)===
{{Main|Mac OS X Server 1.0}}
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. Mac OS X Server 1.0 was based on [[Rhapsody (operating system)|Rhapsody]], a hybrid of [[OpenStep|OPENSTEP]] from NeXT Computer and [[Mac OS 8|Mac OS 8.5.1]]. The [[Graphical user interface|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 [[macOS|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. It could not use [[IEEE 1394|FireWire]] devices. The last release is Mac OS X Server 1.2v3.

===Mac OS X Server 10.0 (Cheetah)===
Mac OS X Server 10.0 (released May 21, 2001) included the new [[Aqua (user interface)|Aqua user interface]], [[Apache HTTP Server|Apache]], [[PHP]], [[MySQL]], [[Apache Tomcat|Tomcat]], [[WebDAV]] support, Macintosh Manager, and [[NetBoot]].

===Mac OS X Server 10.1 (Puma)===
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. Support was added for RAID 0 and RAID 1 storage configurations, and Mac OS 9.2.1 in NetBoot.<ref>{{Cite web|title=Major Mac OS X Server v10.1 Update Now Available|url=https://www.apple.com/newsroom/2001/09/25Major-Mac-OS-X-Server-v10-1-Update-Now-Available/|access-date=2020-11-21|website=Apple Newsroom|language=en-US}}</ref>

===Mac OS X Server 10.2 (Jaguar)===
Mac OS X Server 10.2 (released August 23, 2002) includes updated [[Apple Open Directory|Open Directory]] user and file management, which with this release is based on [[Lightweight Directory Access Protocol|LDAP]], beginning the deprecation of the NeXT-originated [[NetInfo]] architecture. The new Workgroup Manager interface improved configuration significantly. The release also saw major updates to [[NetBoot]] and [[NetInstall]]. Many common network services are provided such as [[Network Time Protocol|NTP]], [[SNMP]], web server ([[Apache HTTP Server|Apache]]), mail server ([[Postfix (software)|Postfix]] and [[Cyrus (imapd)|Cyrus]]), LDAP ([[OpenLDAP]]), [[Apple Filing Protocol|AFP]], and print server. The inclusion of [[Samba software|Samba]] version 3 allows tight integration with [[Microsoft Windows|Windows]] clients and servers. [[MySQL]] v4.0.16 and [[PHP]] v4.3.7 are also included.

===Mac OS X Server 10.3 (Panther)===
Mac OS X Server 10.3 (released October 24, 2003) release includes updated [[Apple Open Directory|Open Directory]] user and file management, which with this release is based on [[Lightweight Directory Access Protocol|LDAP]], beginning the deprecation of the NeXT-originated [[NetInfo]] architecture. The new Workgroup Manager interface improved configuration significantly. Many common network services are provided such as NTP, SNMP, web server ([[Apache HTTP Server|Apache]]), mail server ([[Postfix (software)|Postfix]] and [[Cyrus (imapd)|Cyrus]]), LDAP ([[OpenLDAP]]), [[Apple Filing Protocol|AFP]], and print server. The inclusion of [[Samba software|Samba]] version 3 allows tight integration with [[Microsoft Windows|Windows]] clients and servers. [[MySQL]] v4.0.16 and [[PHP]] v4.3.7 are also included.{{citation needed|date=February 2018}}

===Mac OS X Server 10.4 (Tiger)===
The 10.4 release (April 29, 2005) adds [[64-bit]] application support, [[Access Control Lists]], [[Xgrid]], [[link aggregation]], [[e-mail spam]] filtering ([[SpamAssassin]]), virus detection ([[ClamAV]]), Gateway Setup Assistant, and servers for [[Apple Software Update|Software Update]], [[iChat Server]] using [[Extensible Messaging and Presence Protocol|XMPP]],<ref>{{cite web|url=https://www.apple.com/server/macosx/collaborationservices.html|archive-url=https://web.archive.org/web/20060813212747/http://www.apple.com/server/macosx/collaborationservices.html |title= Apple - Mac OS X Server - Collaboration Services|archive-date=August 13, 2006|access-date=November 25, 2012}}</ref> Boot Camp Assistant, Dashboard, and Weblog Server based on the open-source [[Blojsom]] project ([[Java (programming language)|Java]]).<ref>{{Cite web |date=28 June 2004 |title=Apple Previews Mac OS X Server "Tiger" |url=https://www.apple.com/newsroom/2004/06/28Apple-Previews-Mac-OS-X-Server-Tiger/ |access-date=2022-05-31 |website=Apple Newsroom |language=en-US}}</ref>

On August 10, 2006, Apple announced the first [[Universal Binary]] release of Mac OS X Server, version 10.4.7, supporting both PowerPC and Intel processors. At the same time Apple announced the release of the Intel-based [[Mac Pro]] and [[Xserve]] systems.
===Mac OS X Server 10.5 (Leopard)===
[[File:Leopard Server 10.5.png|right|thumb|Screenshot of OS X Leopard 10.5 Server]]
Leopard Server (released October 26, 2007) sold for $999 for an unlimited-client license.<ref name="In depth with Lion OS X Server">[http://www.anandtech.com/show/4547/mac-os-x-lion-server-review In depth with Lion OS X Server] – Anandtech, August 2, 2011</ref> Mac OS&nbsp;X Server version 10.5.x ‘Leopard’ was the last major version of Mac OS&nbsp;X Server to support [[PowerPC]]-based servers and workstations, such as the Apple [[Xserve G5]] and [[Power Mac G5]].

'''Features:'''
* [[RADIUS]] Server. Leopard Server includes [[FreeRADIUS]] for network authentication. It ships with support for wireless access stations however can be modified into a fully functioning FreeRADIUS server.<ref>{{cite web| url = http://www.macosxhints.com/article.php?story=20071130134610850| title = 10.5: Enable full RADIUS support on OS X Server| website = Mac OS X Hints | archive-url = https://web.archive.org/web/20090918051730/http://www.macosxhints.com/article.php?story=20071130134610850| archive-date = September 18, 2009}}</ref>

=== Server app ===
[[File:Yosemite Server 10.10.png|thumb|The Server app running on OS X Yosemite]]
In releasing the developer preview of [[Mac OS X Lion]] in February 2011, Apple indicated that beginning with Lion, Mac OS X Server would be bundled with the operating system and would not be marketed as a separate product.<ref>{{cite press release|url=https://www.apple.com/newsroom/2011/02/24Apple-Releases-Developer-Preview-of-Mac-OS-X-Lion/ |title=Apple Releases Developer Preview of Mac OS X Lion |publisher=Apple |date=February 24, 2011 |access-date=March 14, 2018}}</ref> However, a few months later, the company said it would instead sell the server components as a [[United States dollar|US$]]49.99 add-on to Lion, distributed through the [[Mac App Store]] (as well as Lion itself).<ref name="lion-june-pr">{{cite press release|url=https://www.apple.com/newsroom/2011/06/06Mac-OS-X-Lion-With-250-New-Features-Available-in-July-From-Mac-App-Store/|title=Mac OS X Lion With 250 New Features Available in July From Mac App Store|publisher=Apple|date=June 6, 2011|access-date=March 14, 2018}}</ref> The combined cost of an upgrade to Lion and the purchase of the OS X Server add-on, which costs approximately US$50,<ref name="In depth with Lion OS X Server" /> was nonetheless significantly lower than the retail cost of Snow Leopard Server (US$499). Lion Server came with unlimited client licenses as did Snow Leopard Server. Lion Server includes new versions of [[iCal Server]], [[Wiki Server]], and [[Mail Server]].<ref name="lion-server-specs">{{cite web |url=http://support.apple.com/kb/SP630 |title=OS X Lion Server - Technical Specifications |author=[[Apple Inc.]] |date=November 15, 2011 |access-date=November 25, 2012}}</ref> More significantly, Lion Server can be used for iOS mobile device management. Starting with Apple Mac OS&nbsp;X Server Version 10.7 “Lion,” [[PostgreSQL]] replaces [[MySQL]] as the database provided with Mac OS&nbsp;X Server, coinciding with [[Oracle Corporation]]’s acquisition of [[Sun Microsystems]] and Oracle’s subsequent attempts to tighten MySQL’s licensing restrictions and to exert influence on MySQL’s previously open and independent development model.<ref>{{cite web|url=https://www2.computerworld.com.au/article/457551/dead_database_walking_mysql_creator_why_future_belongs_mariadb/|title=Dead database walking: MySQL's creator on why the future belongs to MariaDB|last=Pearce|first=Rohan|date=2013-03-28|website=Computerworld.com.au|publisher=[[Computerworld]]|access-date=2020-10-07}}</ref>

Like Lion, Mountain Lion had no separate server edition. An OS X Server package was available for Mountain Lion from the Mac App Store for US$19.99, which included a server management application called Server, as well as other additional administrative tools to manage client profiles and [[Xsan]].<ref>{{cite web|title=OS X Server|url=http://movies.apple.com/media/us/osx/2012/server/docs/OSXServer_Product_Overview.pdf |archive-url=https://web.archive.org/web/20120619100813/http://movies.apple.com/media/us/osx/2012/server/docs/OSXServer_Product_Overview.pdf |archive-date=2012-06-19 |url-status=live|publisher=Apple Inc.|date=June 2012|access-date=July 31, 2012}}</ref><ref>{{cite web|title=Server, simplified: A power user's guide to OS X Server|url=https://arstechnica.com/apple/2012/07/the-server-simplified-a-power-users-guide-to-os-x-server|author=Andrew Cunningham|website=Ars Technica|date=July 29, 2012|access-date=July 31, 2012}}</ref> Mountain Lion Server, like Lion Server, was provided with unlimited client licenses, and once purchased could be run on an unlimited number of systems.

Server 5.7 (released September 28, 2018) stopped bundling open source services such as Calendar Server, Contacts Server, the Mail Server, DNS, DHCP, VPN Server, and Websites.<ref name="about-5.7.1-and-later" /> Included services are now limited to Profile Manager, Open Directory and Xsan.<ref name="about-5.7.1-and-later" />

Server 5.8 (released March 25, 2019) added new restrictions, payloads, and commands to Profile Manager.

The Server app does not support versions of macOS newer than Monterey, marking the end of Mac OS X Server product line.<ref name="about-5.7.1-and-later" />

==Bundled applications==

=== Prior to OS X Mountain Lion ===
One of Mac OS X Server's main administrative tools was the Server Administrator app, which allowed users to configure server services, and turn them on or off.

RAID Admin was a utility for administering and controlling [[RAID|RAIDs]], usually [[Xserve RAID|Xserve RAIDs]]. It was written in Java,<ref>{{Cite press release |title=Apple Unveils New Xserve RAID Storage System |url=https://www.apple.com/au/newsroom/2004/01/06Apple-Unveils-New-Xserve-RAID-Storage-System/ |date=6 January 2004 |publisher=Apple}}</ref> and could run on Windows or Linux.

Other bundled tools include:

* Server Preferences (application)
* [[Server Assistant]]
* [[Server Monitor]]
* [[System Image Utility]]
* [[Workgroup Manager]]
* [[Xgrid|Xgrid Admin]]

=== After OS X Mountain Lion ===
Beginning with the release of [[OS X Mountain Lion]] (version 10.8), there is only one Administrative tool, an app called "Server", which can be bought and downloaded from the [[Mac App Store]], and is updated independently of OS X. This Server tool is used to configure, maintain and monitor one or more macOS Server installations.

== Server services ==
Apple's Address Book Server, iCal Server, Wiki Server, and Web Server are mostly written in the [[Python (programming language)|Python]] programming language, relying on the [[Twisted (software)|Twisted]] framework.<ref name=":0">{{Cite book |last=Dilger |first=Daniel Eran |title=Snow Leopard Server |date=November 2009 |publisher=Wiley |isbn=9780470521311}}</ref> Most{{Clarify|date=February 2023}} of these services were discontinued and removed in version 5.7.1 of the Server app, released on September 30, 2018.

=== Address Book Server ===
Address Book Server is a contacts server, and the first commercial server to have implemented [[CardDAV]], which relies on the [[WebDAV]] protocol. It was added in [[Mac OS X Server#Mac OS X Server 10.6 (Snow Leopard)|Mac OS X Server 10.6]].<ref name=":0" />

=== iCal Server ===
iCal Server is the first commercial calendar server to have implemented the [[CalDAV]] standard, built on top of WebDAV. iCal Server was added in [[Mac OS X Server#Mac OS X Server 10.5 (Leopard)|Mac OS X Server 10.5]], and was also released under the open-source [[Apache License 2.0]] as Darwin Calendar Server.<ref name=":0" />

The server, named "{{mono|caldavd}}", is a [[Daemon (computer software)|daemon]] background service. It has been [[Porting|ported]] to non-Apple computer platforms.  It is currently possible to install it on [[FreeBSD]] and several flavours of [[Linux]]. The server uses an SQL database for storage of calendar data.

=== iChat Server ===
iChat Server is an XMPP server that was added in [[Mac OS X Server#Mac OS X Server 10.4 (Tiger)|Mac OS X Server 10.4]], and was upgraded to version 2 with the release of Mac OS X 10.5 Server in October 2007.<ref>[https://www.apple.com/server/macosx/leopard/more.html Leopard features]</ref> iChat Server was originally based on jabberd 1.4.3 and is named after Apple's [[iChat]] [[online chat]] client software.<ref>[http://opensource.apple.com/source/ChatServer/ChatServer-37.4/jabberd-src/README jabberd14 copyright and version number from source]</ref> Version 2 of the software is based on [[Jabberd2|jabberd2 2.0s9]] and supports server federation,<ref>[http://opensource.apple.com/source/ChatServer/ChatServer-260/jabberd2/README jabberd2 copyright and version number from source]</ref> which allows chat clients to talk directly with other systems that support [[Extensible Messaging and Presence Protocol|XMPP]]. It also supports server-based chat archiving.<ref>[http://www.informationweek.com/news/software/showArticle.jhtml?articleID=198700215&pgno=3 Inside Apple's Leopard Server OS] on [[InformationWeek]], March 27, 2007.</ref>

=== Wiki Server ===
Wiki Server was a set of services which have shipped with all versions of [[Mac OS X Server]] since [[Mac OS X Leopard|v10.5]] until [[macOS High Sierra]]. Mac OS X Server includes web-based [[Wiki]], [[Weblog]], Calendaring, and Contact services. Additionally, it includes a Cocoa application called Directory which allows directory viewing as well as enabling of group services.

Server 5.7.1, the version aligned with [[macOS 10.14]] and released on September 30, 2018, removed the Wiki Server functionality from Server.app.

==Discontinuation==
On April 21, 2022, Apple announced that they have discontinued macOS Server and that the most popular features (Caching Server, File Sharing Server, and Time Machine Server) are already bundled with every copy of macOS High Sierra and later, so customers will still have access to them. Existing macOS Server customers can still download and use the app with macOS Monterey.<ref name="about-5.7.1-and-later" />
