Play on Network lets two people on the same local network play each other. One hosts a game from the sidebar and shares its play code; the other picks it from the list and types the code. Others can watch with a separate watch code, and their clicks never move a piece. Games can be untimed or timed, from 3 + 2 to 30 minutes, and both players can offer, accept or claim a draw, or resign. A player whose connection drops has up to two minutes to come back to the same seat. When a game ends, Review opens it with both players' names. If your clock runs out while your opponent has only a king, the game is a draw. Otherwise it is lost on time, even in the rare positions where no checkmate is possible, such as fully blocked pawn chains. While you play or watch, the engine, hints and the coach are paused everywhere in the app, and the companion only sees that a network game is on. The first time, macOS asks to let Checkmate use the local network. Play on Network appears on macOS 26 and later, and on macOS 14, which was checked in a virtual machine; it does not appear on macOS 15. Automated acceptance covered three copies of the app on the test Mac, real Bonjour discovery between two copies, and a game between two Macs on the same network, played to checkmate with real pointer clicks on both and reviewed on both. In that game the joining Mac lost its connection, through a test-only switch, and came back to its seat. A real cable or Wi-Fi loss was not tested automatically. No person has yet played a network game, or used it with VoiceOver. A crash is fixed: showing a demonstration or a preview line could make the app quit when it ran under Rosetta, because every redraw built a new copy of the chess rules. The board in those views is now read directly from the position. A gate now fails when any app it launches leaves a crash report. Across the app, automated acceptance covered every gate on the test Mac, including the Intel build under Rosetta. A live check, with no microphone or speaker, ran a real coach turn in English, Chinese and Spanish with every narrated segment verified, and a voice preview.
