How to take a timed screenshot in macOS

UI

MacOS Mojave introduced a new screenshot interface with lots of options. One of them being the ability to set up a fixed timer to grab screenshots.

Bring up the screenshot utility by pressing Shift + ⌘ + 5 or by pressing ⌘ + Space and looking for “screenshot.app”
Once in the Screenshot utility, click on Options and select one of the three commands: None, 5 Seconds or 10 Seconds.

Terminal

I recently found out you can also take screenshots using the terminal:

screencapture -C -T10 Desktop/screenshot.png
