MOUNT_APFS(8) System Manager's Manual MOUNT_APFS(8)

mount_apfs — mount an APFS volume

mount_apfs [-o options] [-u user] [-g group] special directory

mount_apfs [-o options] -s snapshot pathname directory

The mount_apfs command attaches the APFS volume indicated by the device special to the global file system namespace at the location indicated by directory. This command is normally executed by diskarbitrationd(8) or mount(8) at boot time.

The special parameter should be the path to an APFS pseudo disk device node, such as /dev/disk0s2s1 (which is a volume inside the container /dev/disk0s2), which can also be specified as simply disk0s2s1.

The options are as follows:

options
Options passed to mount(2) are specified with the -o option followed by a comma separated string of options. See the mount(8) man page for possible options and their meanings. All listed options are currently supported except for the ``force, sync and [no]async'' options.
user
Set the owner of the files in the file system to user. The default owner is the owner of the directory on which the file system is being mounted. The user may be a user-name, or a numeric value.
group
Set the group of the files in the file system to group. The default group is the group of the directory on which the file system is being mounted. The group may be a group-name, or a numeric value.
snapshot
The name of the snapshot to mount. In this usage pathname is the mounted root directory of the base volume containing the snapshot.

The mount_apfs utility exits 0 on success, and >0 if an error occurs.

mount(2), unmount(2), fstab(5), mount(8), umount(8)

The mount_apfs utility first appeared in OS X 10.12.
