If I wipe out the storage device does it wipe out the volumes and container as well?

I ask because it looks like my Mac has two storage devices and a container. What is the most thorough way to wipe out my Mac?

MacBook Pro 13″, macOS 11.6

I ran diskutil and noticed a bunch of extra volumes that I'd like to delete.

From what you posted from diskutil, none of them are "extra."

Everything on your Mac is as it should be.

Big Sur splits the drive into multiple volumes. The two main ones are the System volume (Mac HD) and the Data volume (Mac HD - Data).

Further, it creates a Preboot, VM, Recovery, and Update volume.

The com.apple.os.update.… volume is the Sealed snapshot of the boot volume (Mac HD). The Mac boots from that sealed snapshot which prevents any modification to the OS by anything.

What happens if I wipe everything out? If I plug a bootable Big Sur USB in safe mode will everything be restored? I'd like to start fresh.

You would completely wipe out everything, and then when you re-install, it will look exactly like it does now. You will not have changed a thing, but you will have wasted a lot of time. If it is an M1 Mac, you can possibly render it unusable until you take it to an Apple Store or use Apple Configurator on it from a second Mac.

Again, what you seek to do will not accomplish the goal you seek.

What is one trying to the achieved ?


Is there an issue wherein the computer is not functioning ? Is the computer Mal-functioning ?


Below is the Terminal to list all Volumes on this computer and looks much like yours.


So Suggest leaving the volumes alone as other Contributors have mentioned

If I wipe out the storage device does it wipe out the volumes and container as well?
