iSCPreboot, shown as a volume or folder, containing files and folders.

Hardware, shown as a volume or folder, containing files and folders.

FieldServiceDiagnostic, an empty folder.

Instead, you’re likely to see the following in addition to the expected volumes: While Catalina normally shows what you’d expect, Big Sur isn’t as straightforward. The normal place to look for mounted volumes in Catalina and Big Sur is /System/Volumes. Neither of those is present on external bootable disks for the M1, where the traditional EFI partition is present instead. Instead, they have two additional partitions, named Apple_APFS_ISC and Apple_APFS_Recovery, of about 520 MB and 5 GB size respectively.

Internal disks of M1 Macs are unusual in that they don’t contain a top-level EFI partition. Note that, at least in macOS 11.1, the seal on the unmounted read-only System volume is normally broken, but it’s the snapshot which is the important one: that should be sealed (unless you have broken its seal intentionally).

Recovery, the Recovery Volume, of around 600-950 MB.

Preboot, a small volume of around 350 MB.

The System volume is now the mounted snapshot of a sealed volume known as the Sealed System Volume (SSV):

VM, containing virtual memory caches, which is upwards of 20 KB depending on use.Ĭatalina changes that by splitting the startup volume into two:.

Recovery, the Recovery Volume, of around 500 MB,.

Preboot, a small volume of around 40-50 MB,.

the startup volume, by default on the internal disk named Macintosh HD, which forms the root of the boot file system,.

Within the latter are a minimum of four APFS volumes: I will detail those for release versions of Big Sur in an article next week Catalina and pre-release versions of Big Sur are detailed in this article.Ī standard APFS boot disk in High Sierra and Mojave consists of an EFI partition and the main APFS container. Within the System and Data volumes, standard folders/directories also have fixed layouts, with firmlinks to bind those two volumes together. This article summarises all you need to know about the layout of volumes on APFS boot disks from High Sierra through to Big Sur, running on both Intel and M1 Macs.

When you format a disk and install macOS on it, making it a startup or boot volume, it has a standard structure, something that has changed greatly over the last few years.
