What is the ApplicationsStorageExtension process on macOS? I heard my MacBook Air's fan running loudly, so I opened Activity Monitor. I see that a process named &quot;ApplicationsStorageExtension&quot; has a high number for % CPU. How do I kill that process?

Did you leave About This Mac open with Storage selected?
I think ApplicationsStorageExtension calculates how much storage your Mac is using.
To stop it:

Choose About This Mac from the Apple menu  (located in the top-left corner of your screen).
Close the window that appears.
