MacBook Pro (15-inch, 2016) and later and MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports) and later feature the Touch Bar, which changes automatically based on the application that you're using to show you relevant, familiar tools and controls. On some models, the Esc button appears on the left side of the Touch Bar, in the same place the physical Esc key appears on traditional keyboards.

1. Kerbal Space Program is a multi-genre game with a deep and complex gameplay. In KSP, you have to create a spaceship which will be able to safely take your crew into the space.
2. Qt::Modifier keys, cursor movement keys, function keys and miscellaneous action keys (e.g. Escape, Enter, Backspace, PrintScreen) will stop key event compression, even if there are more compressible key events available. Platforms other than Mac and X11 do not support this compression, in which case turning it on will have no effect.

4. For a more reliable replacement, OS X Daily suggests manually mapping Caps Lock to Escape, which has the added benefit of shutting you down every time you’re about to shout. Use of k eyboard.

The two biggest improvements are screen resolution and the mouse. The mouse in will now work seamlessly between OS X and the PC window, no keyboard use required. Move the cursor outside the PC window, and OS X owns it. When it's over the PC window, it belongs to the PC. Also, all the 'jerkiness' in mouse movement disappears.

Sometimes tools in the Touch Bar temporarily cover the Esc button:

After you tap or the Done button, Esc reappears.

How to use another key as Esc

You can choose a physical key to act as Esc, temporarily or permanently:

1. Choose Apple menu  > System Preferences.
2. Select Keyboard.
3. In Keyboard preferences, click Modifier Keys.
4. Use one of the pop-up menus to choose another key to act as Esc.
   

For example, if you choose Escape to the right of the Control (^) Key label, pressing Control has the same results as pressing Esc: it closes menus that are open, and pressing Control-Option-Command makes the Force Quit Applications window appear.

You can return your keyboard to its original behavior by clicking Restore Defaults.

How to force apps to quit using Esc alternatives

You might not be able to use the Esc button in the Touch Bar if the app you're using becomes unresponsive.

If you need to use Esc to force an app to close, you can switch to another app and try Option-Command-Escape. You can also choose Apple menu > Force Quit.

If that doesn't work, or if your Touch Bar doesn't respond in any app, restart your Mac. Choose Apple menu > Restart or, if your Mac isn't responding, press and hold Touch ID (power button) until your Mac turns off.
