Yours truly, over on MacStories:
Within the next few months, macOS Server as we know it today will be going away, with many of its services being deprecated. Things like hosting calendars, contacts, email and wikis are going away as Apple focuses the product on “management of computers, devices, and storage on your network.”
This shouldn’t come as a surprise. macOS Server has been languishing for years, with many of its most common features being integrated into the mainstream version of macOS.
For fans of macOS Server, this just another in a long string of disappointments over the years. But none of them were as big as the cancellation of the Xserve, Apple’s rack-mountable 1U server, back in January 2011.
