CocoaMines is a Minesweeper clone for MacOSX, written entirely in Objective C, using Apple's Cocoa Frameworks. CocoaMines is currently localized for English and German (Please e-mail me if you could translate for another language or clean up the admittedly crude German Translation). Basic gameplay (flagging mines, timed games) and Preference file support has been implimented, however I intend to add the ability to keep a high score list.
What's new in CocoaMines for OSX
Version 1.2.6 fixes the following:
Fixed a bug which caused a discrepancy between the number of mines on the field, and the number reported.
Changed the "About CocoaMines" box so that the text is selectable, allowing copying of e-mail addresses.
