How to access Yosemite MAC partition from Linux

As an addict and old user of the i3 tiling wm. I couldn't use MAC OS more that 6 months, than I decided install Linux in my MAC bookair :D

However this computer offers only 128GB of SSD and I was with many work files, than I needed access this files on my MAC partition, for this I installed the hfsplus-tools avaliable in my Linux distribution, but I can't mount my MAC partition :(

Some research found that Yosemite change its partition from HFS+ to "Core Storage", but is possible do you convert Yosemite’s Core Storage partition back to HFS+. Let's go.

On MAC terminal use the command shown below to get the lvUUID for the partition.

diskutil cs list

This will give you a list of partitions similar to this:

            Volume Name:           OS X Test
            Content Hint:          Apple_HFS

If the partition says “Revertible: Yes”? That means we can convert it back.
Use the command shown below to revert this partition to HFS+

diskutil coreStorage revert 2F7B1893-07E8-4298-840B-F2552042E055

Now, come back to Linux and mount your MAC partition normally.

mount -t hfsplus -o force,rw /dev/sda2 /mnt/apple

Good luck
