Stacks basically cleans up your desktop by automatically arranging all your content into organized groups of files that can easily be expanded with a click. This feature can be very useful, especially for people like me who have to save everything to the desktop and then clean it up once or twice a month. The effect that Stacks has on tidying up your desktop is easily visible. You can try it for yourself by following the steps below. Note: you’ll need macOS Mojave or later to enable and use Stacks on your Mac.
Open Finder.
In the upper-left Finder menu, click on View and select “Use Stacks.”
All your desktop files will now be automatically sorted out group-wise, as determined by macOS.
The neat feature about Stacks is that is doesn’t randomly create groups for your files but groups them by file type (for example, Documents, Images, Films, Spreadsheets, etc.). This allows you to find whatever you need quickly without any fuss. However, do note that Stacks will only organize the files present on your desktop. All folders will be left as they are.
Organizing the Stacks
You can organize the stacks by various dates or by any file tags you may have added. To do this, open the View pane again, and select your desired sorting option from “Group Stacks By.”
Once you click on a Stack, it’ll expand, displaying all your files. You can then interact with them (rename, drag, drop, etc.) as you normally would. For old time macOS users, this feature might sound familiar; it was previously (and still is) present for creating stacks for the Documents and Downloads folder in the Dock. However, Apple decided to extend the feature to the desktop in the latest version of macOS Mojave, and we’re glad they decided to! If you later want to revert back to the standard layout, simply uncheck the “Use Stacks” option in the Finder View menu.
