In macOS Mojave, Apple introduced a brand new screenshot tool that combines features from many of its previous versions. Don’t worry: Command + Shift + ¾ are still there, but the Grab app is gone.
New is a Command + Shift + 5 shortcut. This triggers a screenshot tool with more flexibility and on-screen options. A bar along the bottom allows you to pick between snapping different types of windows, starting screen recordings, saving directly into a variety of apps, and triggering a timer.
It’s certainly a change. But after playing around with it, I really like and wish it had arrived a while ago.
