Booted to Windows how do I enable access to a Mac CoreStorage volume?
Instead of a default/classical Mac volume like your iMac, your MacBook Pro contains a CoreStorage volume.

Booted to Windows, CoreStorage volumes cannot be mounted and consequently the contained files can't be read - until now.

You would need to revert the CoreStorage volume wrapper that contains HFS+ back to a straight HFS+ volume to regain read-only access.

I'm surprised Apple doesn't have KB article on this, but look here:


Why I can not see mac partition under windows installed with bootcamp?
Can&#39;t make more than two partitions


Basically, boot to Recovery HD (or another external Mac volume) and then issue the command:

diskutil cs revert E21EC611-3794-4B0D-BFDB-299510FCDFAB


That would take partition 2 on disk0 (the Core Storage part) and revert it to the HFS+ or classic disk layout that Windows knows how to read.
