Why Is My Macintosh HD – Data Partition Not Mounted?

I noticed that my hard drive is divided into two partitions. They are Macintosh HD and Macintosh HD – Data. I also noticed that while the Macintosh HD Partition is mounted the Macintosh HD – Data portion is not mounted. Is this normal? I’m viewing this in disk utilities in recovery mode.

I was working with apples tech-support on an issue I had and was in recovery mode when I noticed that my Macintosh HD – Data partion was not mounted. While the Mac Hd was. Is this normal?

    Starting with Catalina, this is how it works. The System is on a special read-only partition. The rest of your files are on the “Data” partition. This is a great security measure. The way it is designed, you see both as one “Macintosh HD” as normal with your System in the right place, just not modifiable.

    But why is the HD – Data portion listed as “not mounted” while the system portion is mounted?

    George: That’s just the way it is represented in Disk Utility. It isn’t “mounted” as a separate drive. This isn’t something you need to manage or take an action here — it is working as it should.
