Apple has introduced a new interface for screen shots and screen recordings in macOS Mojave. Let’s have a look at how it works.

To bring up the new interface press Shift-Command (⌘)-5.

 Capture the entire screen

• Your pointer changes to a camera.
• Click any screen to capture that screen or click Capture in the onscreen controls.

You can also still use the old school shortcut: Shift-Command (⌘)-3

 Capture the selected window

• Your pointer changes to a camera.
• Click a window to capture that window.

You can also still use the old school shortcut: Shift-Command (⌘)-4

 Capture a selected portion of the screen

• Drag to select an area of the screen to capture.
• To move the entire selection, drag from within the selection.
• Click Capture in the onscreen controls.

You can also still use the old school shortcut: Shift-Command (⌘)-4

Edit & Share

After you take the screenshot a thumbnail of it briefly appears in the bottom right of your screen.

• If you do nothing or swipe the thumbnail to the right the screenshot is saved.
• You can click the thumbnail to open the screenshot. You can then edit it or share it.
• Drag the thumbnail to move the screenshot to a document, an email, a Finder window or the Trash.
