OS X Server

OS X Server is Apple's implementation of a server environment especially tuned to run on Macintosh computers. These days, OS X Server exists as a $19 download from the Mac App Store. It turns any Mac running Mavericks into a server capable of supporting workgroups and businesses large and small.

OS X Server incorporates file sharing capabilities, profile manager support to help with the unified management of Macs and iOS devices, a caching server to enable administrators to collect and distribute Mac and iOS software updates, Xcode Server for developers, unified Time Machine backup, a Wiki server, services for shared calendar, contacts and mail, and Xsan 3, Apple's implementation of a Storage Area Network system, an advanced file sharing system. There's much more, too — Messages server, NetInstall support, and VPN Server. All this for a ridiculously low price: $19.99.

It's largely a trivia point, but OS X Server actually predates the release of the client version of OS X. The first version of Mac OS X Server was released in March of 1999, more than a year before Apple would release a public beta of OS X for everyone else.

That first release was a very different server than we know today. A melange of NeXT's OpenStep operating system and Mac OS 8, it provided the ability to share files, manage QuickTime streaming services, run Apple's WebObjects application server software and more.

Eventually Apple would release OS X Server in lockstep with the client release of OS X, offering up the software for enterprise IT managers and others. Apple steadily increased the capabilities of the software with web publishing, migration software to make switching from Windows servers easier, e-mail server support, proxy/cache service to make managing Mac (and eventually iOS) downloads easier, and much more.

For a long time Apple sold the software for $999 with an unlimited user license, or $499 for a 10-user license. Apple eventually halved the unlimited user price to $499 and dropped the 10-user tier all together.

Then with the release of OS X Lion 10.7 in 2011, Apple took a radically different path. OS X and OS X Server were no longer two distinct operating systems — there was just Mac OS X. Lion Server existed as a $49 download from the Mac App Store, and this represented another huge drop in price: administrators would be out a scant $99 for an unlimited user license.

Today OS X Server remains available as a download from the Mac App Store, but the price has been further reduced to $19.99. The software is squarely aimed at small businesses, schools and enterprise workgroups.

Apple also offers a specially configured Mac mini with OS X Server preinstalled (with double the hard disk space), for $999.
