Based on this article from apple, I'm going to assume Chess app is not the only app you can't hide. It says System Integrity Protection includes protection for these parts of the system: Apps that are pre-installed with OS X. The moving and/or hiding issue you are having is because of SIP. Play chess online for free on Chess.com with over 50 million members from around the world. Have fun playing with friends or challenging the computer! As a new and learning chess player this app is useful but as an avid proficient chess player, it's equivalent to playing with a real person who tries to cheat. Chess is a game of challenging strategy and there is absolutely no room for cheating. Perhaps I'll check back on the app. To restore the proper default app, verify the app icon is the same as the default app on the iOS device, and that the developer of the app is Apple. You can also follow direct App Store links to the iOS default apps if you don’t want to bother with the Search function in the App Store of the device. The easiest way to get started is with the Stockfish app: If you want the engine only, you can get it through Homebrew: brew install stockfish. Note: The Stockfish chess engine is a command line program. You may want to use it in your own UCI-compatible chess GUI.

If you have every watched a chess video on YouTube, or chess streamers on ChessTV, you have probably seen them drawing orange arrows on their screen to explain their moves.

How do they do that? It's easy! And it is a feature everyone on Chess.com can use.

How to draw arrows on your board

You can do this on any board automatically, except in Live chess. To enable this option in Live chess, click on the gear icon next to the board:

Then toggle the switch to draw arrows and highlights. Don't forget to click save!

You can also find this option in your account settings under the Live Chess settings.

Controls

To draw an arrow simply right-click and drag your mouse across the board in the direction you want the arrow to point. Please see here for how to right-click on a Mac if you don't have a two button mouse!

To draw a knight's move arrow, click and drag over the squares you want the arrow to cover. When you let go of the right mouse button the arrow will appear. The point of the arrow will be wherever you let go of your mouse button.

Colors

The default arrow is yellow, but you can also hold Ctrl to draw a red arrow, hold Alt to draw a blue arrow, or hold Shift to draw a green arrow.

Try it on any board on Chess.com to practice!

You can also highlight squares by right clicking. Similar to arrows, you can choose to highlight in red, green, yellow or blue color. But in the case of squares, the default color is red.

Right click on the square to turn it red

Control+Right click on the square to turn it yellow

Alt+Right click on the square to turn it blue

Shift+Right click on the square to turn it green

To clear all arrows and colors from the board, simply left click anywhere on the board.
