macOS Server is server software. In 1999, 'Mac OS Server 1.0' was released, and in March 2001, 'Mac OS X Server 10.0' was released. However, since Mac OS Server 1.0, which was first released, was developed in the BSD / NEXTSTEP series, it is completely different from the current macOS Server.

MacOS Server, which inherits the flow from Mac OS X Server 10.0, was sold at the Mac App Store for 2440 yen including tax. However, when I visited the sales page of the Mac App Store at the time of writing the article, it displayed 'App not available' and I can no longer purchase it.

In addition, existing macOS Server users can continue to download the application with macOS Monterey .

The server features of macOS Server, Caching Server, File Sharing Server, and Time Machine Server, are bundled with all macOS since macOS High Sierra, so users didn't have to purchase macOS Server separately.

In addition, Apple has already phased out major services such as calendar and contact support, dynamic host configuration protocol (DHCP), DNS, mail, instant messaging, etc. that were provided by macOS Server from around 2018. , Suggests alternative services in support documentation.
