Not the first port of Minesweeper to Mac OS - but a nice one and hey, it's a new 2025 game for our Mac OS! It is reminiscent of the legendary Windows Minesweeper, comes as a Desk Accessory (hence the "DA" in the name) but runs fine on OS 9 as well. Minesweeper DA and its source code can be obtained from the respective Mac Garden page.
