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.
