Arch Linux: DMG Image Mount

How to mount Apple’s macOS disk image (DMG) under Arch Linux…

Kernel Support Check

The condition is to have built in or compiled kernel drivers for HFS/XFS. In can be checked in Arch Linux as follows:

$ zcat /proc/config.gz | grep XFS
CONFIG_XFS_FS=m
CONFIG_XFS_QUOTA=y
CONFIG_XFS_POSIX_ACL=y
CONFIG_XFS_RT=y
# CONFIG_XFS_WARN is not set
# CONFIG_XFS_DEBUG is not set
# CONFIG_VXFS_FS is not set

In Gentoo (or in any other linux distro where the kernel was manually built), it can be checked as follows:

$ grep XFS /usr/src/linux/.config
CONFIG_XFS_FS=y
