I tried to remove Chess.app from my Mac: Moving to Trash: 'Chess.app' can't be modified or deleted because it's required by macOS. Trying to change permissions for everyone in Get Info: The operation can't be completed because you don't have the necessary permission. The history of macOS, Apple's current Mac operating system originally named Mac OS X until 2012 and then OS X until 2016, began with the company's project to replace its 'classic' Mac OS. That system, up to and including its final release Mac OS 9, was a direct descendant of the operating system Apple had used in its Macintosh computers since. Sigma Chess is a freeware, master strength Macintosh chess program for Mac OS X. With Sigma Chess: Sigma Chess supports. Your own free text annotations. Chess uses the javascript chess engine and interface made by Sven Vahar to play chess against the computer. Note: The Stockfish chess engine is a command line program. You may want to use it in your own UCI-compatible chess GUI.
Since OS X 10.2 Apple has included a Chess game by default on your Mac. The current version allows you to play against the computer with varying difficultly levels, play against another person, and even play online. You can change the look of the 3D board, hear moves and even speak to make a move. You can also save and resume games.Check out Play Chess On Your Mac at YouTube for closed captioning and more options.
Video Transcript: Hi, this is Gary with MacMost.com. Did you know that a chess game comes with your Mac and it has for a long time. You can find it in the Applications folder, it's right there, or just launch it with Spotlight by using Command space and typing chess. It's a pretty versatile app. It asks you to sign in with iCloud, I'll tell you why later, but for now you can just cancel and skip that. So, you can start a new game and there are several different modes in this chess game. You can do different variations on chess and you can also play human versus human. So you don't need a chess board with you. If you've got your MacBook with you, you can play with the person sitting next you. You can also do human versus computer and reverse the situation there. You can even have a computer versus computer game where they play each other. Now, once you start you can set the number of seconds that the computer thinks per move. The more time you give the computer to think the tougher it's going to be. So you start. Now you just move the pieces as normal. Just drag and drop. Then the computer will make its move and even call it out for you. So you've got this little microphone here and you can even show the moves there so you can see all the different moves. There are a whole bunch of other options as well. So, for instance, you can go into Chess Preferences here and you can set the board to be something different like a metallic board. You can even change it during the game and the pieces as well. Lots of fun options there. You can turn off the speaking moves right there. Even change the voice that the moves are spoken in. You can change the intelligence of the computer right in the middle of the game if you wish. You can even speak your own moves and it will understand you. You don't even have to click anything or hold a key down. It's always listening. I'm going to create a pause hear so it starts listening and speak a move. Pawn E2 to E4. Pawn C7 to C6.There is a bunch of other options as well. For instance you can take back the last move. You can have it show a Hint. You can have it reshow the last move if you missed it. Check this out. You can save a game. So in the middle of a game you can save it and then open that game later on to resume it. So you can have multiple games going at the same time or pause to continue the game another day. Now I mentioned that you can also do multi player and that's what that iCloud sign in was before. If I do New and I choose Game Center Match there, then I hit Start and it allows me to connect with people I'm connected to using Game Center. If you're not familiar with Game Center it is a whole other subject. But it is a nice thing to be able to do. The one last thing I want to show you is that notice that this is a 3D view of a chess board. So you can click and hold any corner of the board and then drag to change the view. You can rotate it all the way around and you can kind of drag it up and down just to get a slightly different view of the board if you want.Legaroid's Chess Mac Os Update

What can I do with ExaChess?
If you use a Mac and enjoy chess, whether as a casual player wanting a bit of fun or as a serious student of the game, then ExaChess has something to offer you.
ExaChess as a chess database. If you haven'tused a chess database before, here's what you can do with ExaChess and areasonably sized game collection:
- Use it for entertainment. Pick a game at random and play through it -- choose a game by one of the leading grandmasters from a recent tournament, or a classic win by a past champion, or a quick win in one of your favourite openings, or a recent pawn and rook ending. A chess database gives you instant replays at a pace you control of thousands of entertaining games.
- Study openings. Assemble a collection of games in one of your favorite openings, or defenses, or a new line you are trying to learn. Find what other players have played in the same positions, and with what success ratios. Play against the database to check for holes in your opening repertoire or to check your memory. Explore deviations off the main line.
- Study middlegame themes and combinations. Look for combinations and sacrifices. Find how the Masters proceed as a particular opening line moves into the middlegame.
- Study endgames. Find where a rook draws against rook and pawn. When do bishops of opposite color draw and when don't they?
- Prepare a database. Build a database of your own games, or of games from a recent or historical event. ExaChess has a powerful game parser to extract games with annotations from a wide range of text sources. It allows fast duplicate finding and removal, easy merging of games with other databases, conversion of databases to other file formats, and can use databases in other file formats without conversion.
ExaChess as a chessboard. It's easy to move thepieces, take back moves, add annotations, keep a move tree of all the linesyou explore.
- Play through a game. It's quicker than setting up a board. You can instantly wind the game back or forward to any point. Move entry is easy: type the moves, choose them from a menu, drag pieces with the mouse, or use the move prediction feature to just click on the destination square and have ExaChess play the most likely piece to that square.
- Use as an analysis board. It's ideal for correspondence chess. Try out and save all your candidate moves and all sidelines of play with all their sub-sidelines. Once you investigate any line of play, you have it forever. No more going back through the same lines, over and over. Add comments. ExaChess makes it easy to keep detailed annotations on any number of games in progress. A huge advantage over analyzing with a board and pieces.

ExaChess as a chess partner. Its built-in enginelets you play against the database to test your opening repertoire. It workswith external chess engines, providing the user interface while a chessplaying program calculates the moves, and can host a match between two chessplaying programs.
- Play speed chess against the computer. Or play serious games. Practise banging out opening moves in your favorite lines, or checkmating your opponent when you have a large material edge but only seconds left on the clock.
- Analyse your own games. Play through them again. Ask a chess engine to find its best move in a critical position, or to annotate the whole game. Play against the computer in a side variation -- can you still win?
ExaChess as a chess publisher. It can directlyprint games with full formatting, figurines and diagrams. It can export asingle game or a whole database of games with formatting, figurines, anddiagrams in RTF (Rich Text Format) format for import into word processors orpage layout programs.
- Annotate your own games and print the analysis. Write your own book of best games.
- Publish a book on an opening you've studied with example games from the database.
