Why is my Macintosh Data partition completely empty?

When I view "About My Mac" it shows that I have 87GB available of a 500GB. But when I view the Macintosh Data partition using the Finder, it shows zero files. How am I supposed to make sense of this? Are my documents, videos, and music supposed to be stored on the Macintosh Data partition?


I'm using Big Sur.


Thank you.

When I clicked the minus icon, a scary warning came up that said all data will be deleted and this can not be undone. I don't get why this volume is supposedly only using 934KB, and yet there also seems to be roughly 500GB of data in 6 other volumes. I don't know what those other volumes are, so I'm not sure how to proceed. Obviously I don't want to risk losing data, unless I know what that data is.


Thanks for helping!

That's not your Data volume. It is an orphaned Data volume, probably from a reinstall where you didn't remove the old one.


Open Disk Utility and select each - Data volume.

Look at the Mount Point in the info pane.

The volume mounted at /System/Volumes/Data is the correct one.

The one volume mounted at /Volumes is the orphan (and the one showing up in the Storage display and the Sidebar).

That Volume is inside the same Container as your Macintosh HD and Macintosh HD - Data. That's why you see "Other Volumes" with 447GB of data. About 20GB are on Macintosh HD and the rest is on Macintosh HD - Data (the good one).


If you select "Show All Devices" from the View Popup menu, you will see all of the volumes contained in Container Disk X.

An APFS Container is like a partition, but it is divided up by Volumes. All of the Volumes in the container share the same storage space.

So, you have a 500GB drive with one APFS Container (of roughly the same size). All of the volumes, Macintosh HD, Macintosh HD - Data, your other Macintosh HD - Data, and a few system volumes all share the same 500GB of storage, taking whatever they need.
