Quick Actions are a new type of system extension for manipulating files from the Finder’s Preview pane or the Touch Bar. The other new feature of the Preview pane is Quick Actions, which are located at the bottom of the pane. One drawback though is that for some types of files, like video files, the metadata window can get very long, so viewing it isn’t a great experience on a smaller laptop screen. If you work with the same types of files over and over, you probably need certain data about them time and again, which is what makes the new Preview options so powerful. Although everyone has hundreds of different kinds of files on their Mac, most people probably only work with a handful on a regular basis. The ability to customize the Preview pane on a per-filetype basis makes it much more useful.

Just tick off the checkboxes for the data you care about and you’ll see the information appear in the Preview pane. That will open a separate window with a list of every bit of metadata that can be shown in the Preview pane for the currently-selected file type. From the Finder’s View menu you can select the new Show Preview Options menu item. The same information available in the High Sierra Preview pane is in Mojave too, but there are options to include so much more. Use the shortcut ⌘⇧P to open the pane if it’s not showing in your current Finder view. If that sounds like you, I’d suggest giving it another try.

Until recently, I rarely kept the Finder’s Preview pane open. The Preview pane got much more useful with Mojave too. Show Preview Options opens a separate window of all the metadata that can be displayed for a file.
