serverOS – The Xserve was the Apple server until November 5, 2010 that was officially discontinued, offering as an alternative the Mac Mini Server or the Mac Pro, but none of these machines are designed with server-grade hardware in mind and are not a real replacement.

Over time the server versions of macOS were suppressed and replaced with the client versions, a more user-oriented operating system rather than a server-oriented operating system, eliminating all the server tools and replacing them with the weak "Server.app" application.

However, in April 2018 in macOS High Sierra, all server functions of the Server.app application were deprecated by Apple, leaving it to offer server software for Mac forever.

serverOS, seeks to give a new life to Mac servers giving the possibility of installing the latest versions of macOS on unsupported machines and bringing back part of the server-oriented functionality lost in previous versions.

Xserve LOM Configurator, allows you to configure the Xserve's Lights Out Management ports from a modern macOS installation.

All the official Apple applications from the Server Tools package directly from OS X Snow Leopard Server, has been patched and modified in order to work in newer versions of macOS.

Add support for third-party NVMe Drives, USB 3 and SATA 3 PCI-E cards, adding Xserve support to the latest standards and connectivity protocols.

The creation of the distribution package and the management of the dependencies are handled by Packages, a macOS application.

./build.sh

Before proceeding with the installation of serverOS you must disable SIP in your macOS installation.

The distribution package must be compiled using the Packages application, once the installation package is done it will be available in the build folder.

This package can be installed just like any other package by running it.

If the installation of the package fails, it may be due to Gatekeeper so it will be necessary to install the package through the terminal by running it using sudo.

sudo ./install_homebrew
sudo installer -pkg "./build/serverOS.pkg" -target /
