Treat the Mac mini as a quiet Agent server. macOS already includes Screen Sharing, and RealVNC Viewer on Windows can take over the desktop whenever configuration, upgrades, or troubleshooting require a GUI.</p> <p>This is especially useful in a Windows-first home or studio where the Mac mini runs continuously at relatively low power while the Windows machines remain the daily workstations. The installation is rarely the difficult part. Most failures come from Screen Sharing, user authorization, VNC credentials, network reachability, sleep behavior, or services that do not recover after a restart.</p> <p>One rule matters more than every convenience tweak in this guide: <strong>do not expose TCP port 5900 directly to the public Internet.</strong> A same-LAN connection is the simplest starting point. For access across networks, first join a self-hosted VPN or another controlled private network, and only then connect to the Mac.</p> </blockquote>
