Why does macOS create file mounts for each app? I installed a lot of apps on my new MacBook, and I can see my desktop is filling with file mounts for each app. The Finder is also listing them like this.



Can someone please help me understand why that happens? What is the use of those mounts? Is there a way I can control/hide/stop that?
These seem to be installers DMGs. You can unmount and discard them after installing the apps in your computer, typically by copying them to /Applications or ~/Applications.
