Drag Files into Stage Manager Apps on macOS 13

Yes, you can drag files directly into application windows docked in the Stage Manager sidebar in macOS 13 Ventura. While you cannot immediately drop a file onto a minimized thumbnail to process it directly, macOS supports a "spring-loading" action that allows you to drag a file over an inactive window to bring it to the center stage, where you can complete the drop.

How to Drag and Drop Files Using Stage Manager

  1. Select the File: Click and hold the file or folder you want to move from your desktop, Finder, or an open application.
  2. Hover Over the Docked App: Drag the file toward the Stage Manager strip on the left side of your screen and hover the cursor over the thumbnail of the target app.
  3. Wait for Spring-Loading: Keep the cursor held over the thumbnail for a brief moment. The thumbnail will activate, bringing that application window into the center of your screen while sending your previous window back to the strip.
  4. Drop the File: Once the target app is expanded and active, drag the cursor over the document, message, or upload area and release the mouse or trackpad button to drop the file.

Adding Files by Creating App Groups

If you frequently transfer files between a Finder window and a specific app, you can create a temporary group in Stage Manager:

  • Drag the target app out of the Stage Manager strip and place it next to your open Finder window.
  • Both windows will now share the center stage simultaneously.
  • Drag and drop your files directly between the two open windows without waiting for the hover delay.
  • When finished, drag the app back to the left sidebar to ungroup them.

Troubleshooting Drag-and-Drop Issues

If hovering over a thumbnail does not bring the window forward, verify your system settings:

  • Spring-loading delay: Go to System Settings > Accessibility > Pointer Control and ensure Spring-loading is enabled. You can adjust the spring-loading speed slider to make the windows pop open faster when hovering.
  • App compatibility: Ensure the target application supports the specific file format you are attempting to drop into it.
