When you take a screenshot on a modern Mac (using the standard Cmd + Shift + 3 or Cmd + Shift + 4 shortcuts), macOS does not immediately save the image to your desktop. Instead, it places a small, floating thumbnail of the screenshot in the bottom-right corner of your screen. This thumbnail lingers for approximately five seconds before finally saving the file to your designated folder.
Apple introduced this feature to allow users to quickly click the thumbnail to annotate or crop the image. However, if you are a power user who needs to take dozens of rapid-fire screenshots in quick succession, this floating thumbnail becomes a massive roadblock. Not only does it delay the file from actually appearing in Finder, but if you take a second screenshot while the first thumbnail is still on-screen, the thumbnail itself will be captured in your new image. If you prefer the old, instantaneous behaviour where screenshots save immediately with no preview, you can easily disable the floating thumbnail.
Disabling the Floating Thumbnail via the Screenshot App
You do not need to dive into System Settings to fix this; the toggle is located directly within the built-in Screenshot utility.
- Press the keyboard shortcut Cmd + Shift + 5. This will bring up the advanced on-screen screenshot control bar (usually located near the bottom middle of your screen).
- On this control bar, look for the button labelled Options and click it.
- A dropdown menu will appear with several sections (Save to, Timer, Options).
- Look under the bottom “Options” section of this menu.
- You will see a setting labelled Show Floating Thumbnail. It will likely have a checkmark next to it.
- Click on Show Floating Thumbnail to uncheck it.
- Press the Esc key on your keyboard to close the screenshot control bar.
The change is instantaneous. The next time you press Cmd + Shift + 3, your screen will flash, you will hear the camera shutter sound, and the image file will appear instantly on your desktop, exactly as it did in older versions of macOS.
