So after I upgraded my MBP to Yosemite, I have lost dualboot. After a long struggle, I finally reinstalled refind to work properly. Unfortuantelly, when I use Ubuntu, I cannot access Macintosh HD drive anymore... Is anyone having a same problem? If so, is there a way to fix it?
First, if you intend to write to the HFS partition from Ubuntu, you need to disable journaling on your Mac
On your Ubuntu install
sudo apt-get install hfsprogs hfsplus libhfsp0 libguestfs-hfsplus hfsutils
Check your partition as montioned @Adam Zahran :
sudo fsck.hfsplus -f /dev/sdXY
Mount Mac partition:
sudo mkdir /mnt/your_mount_point sudo mount -t hfsplus -o force,rw /dev/sdXY /mnt/your_mount_point
The same thing happened to me, I ran:
sudo fsck.hfsplus -f /dev/sda2
and then tried again and it worked perfectly.
Note: You should replace
/dev/sda2 to whatever corresponds to your Macintosh partition.
