Mount hfsplus and hfs read write on Linux

Mount HFS+ rw on Linux (at your own risk...)

# Install HFS+ support
aptitude install hfsplus hfsprogs hfsutils
# Keep an eye on your dmesg:
tail -f /var/log/messages
# Get an idea on what partition you'd want to mount
cat /proc/partitions
# See what filesystems are supported
cat /proc/filesystems
# Check for a hfsplus LKM
modprobe -l | grep hfsplus
# Load it
modprobe hfsplus
# Check to see if it's loaded
grep hfsplus /proc/partitions
# Mount the HFS+ partition. If it's journaled, we don't need -o force.
mount -t hfsplus -o force -o rw /dev/sda2 /mnt/test
# Verify it
/dev/sda2 on /mnt/test type hfsplus (rw,force) touch /mnt/test/selftest ls -la /mnt/test/selftest
# If we're not allowed to mount with the write option, check dmesg
# If required, fsck, then remount.
/sbin/fsck.hfsplus -f /dev/sda2
# As an alternative, you can disable the journal on a MacOS:
# GUI: hold option while clicking the menu in Disk Utility. CMD:
diskutil list
sudo diskutil disableJournal /Volumes/Yourdisk
