Taking a screenshot of a window in macOS is easy, even if it is a bit of a hand-twister key combination. It's done by by pressing Shift-Command-4 and then Space bar and clicking the window you want to screenshot. If you've got a Mac with the Touch Bar, you can customise it to always display a screenshot shortcut. Both these methods add a 56 pixel shadow to the window you're taking a screenshot of. This shadow may add a cool visual effect to the UI but is a pain to deal with when it's a part of the screenshot. Read on for how to disable it.

If you don't want to make a permanent change to your Mac's configuration, simply hold down the Alt/Option key after pressing Space and clicking on the window. This will disable the shadow for that one screenshot.
