Q: How can one access mac partition files on bootcamp drive?

I've created a partition on my hard disk for the purpose of running windows through Boot Camp assistant. When I log into windows everything works fine but I'm not able to access the files that are stored on my Mac partition part. Not even read-only access. How do I enable this?

MacBook Pro, OS X Yosemite (10.10.4)

    If you run Yosemite or higher, the OS X file system is a CoreStorage volume. There are no Windows drivers that allow such readability. If you must, there are Terminal commands which will allow readability.

     

    Please post the text output (not a screen shot) of the following Terminal commands from OS X side.

    Your CS volume is revertible to plain JHFS+ volume as indicated by

    Revertible:            Yes (unlock and decryption required)

    If you use FileVault, you will not be able to see OSX volume on the Windows side.

     

    1. Disable FileVault - https://support.apple.com/kb/PH18674?locale=en_US&viewlocale=en_US .

    2. Check diskutil cs list for any CS volumes. If they exist use diskutil cs revert command.

    3. You should be able to see OSX on the Windows side after step 2.

    In the revertible section it says no, now that I've turned off FireVault but still can't access the drive for bootcamp windows 10.

    Your BC drivers are not installed properly. You are missing AppleHFS.sys and AppleMNT.sys on W10 side. Please download appropriate drivers from System requirements to install Windows on your Mac using Boot Camp - Apple Support and Boot Camp: Install or repair Boot Camp drivers.
