One feature of macOS Mojave I’m loving is Continuity Camera, which lets you use your iDevice’s camera to take photos or scan documents, which then appear on your Mac!
It currently works in the Finder and many Apple apps that accept typed input (i.e. Pages, Keynote, Mail, Messages, Notes, and TextEdit to name a few). The easiest way to determine if it’s available is to right (or Control) -click in a document or on the Finder’s desktop. If Import from iPhone or iPad appears in the shortcut menu, select the iOS device you wish to use and choose Take Photo or Scan Document.
If you right-click in a document (i.e. not the Desktop or Finder), the photo or scan will appear at the insertion point; if you right-click on the Desktop or in a Finder window, the photo or scan will appear on the Desktop by default.
