Q: Windows 10 Anniversary + Boot Camp = no longer mounting Mac partition

I have a Retina MacBook Pro (Late 2013) with Mac OS El Capitan, dual-booting with Windows 10 with Boot Camp installed. Everything was working fine until I installed the Windows 10 Anniversary Update today; now Windows no longer mounts the Mac partition. I successfully reinstalled the latest Boot Camp drivers, but Windows still won't show me the Mac partition. (Booting into Mac OS works fine.)

 

Is anyone else seeing this problem? Anyone know of a solution or workaround?

    I have a 12 inch Retina Macbook that has Windows 10 build 1511 on it, and I can't see my mac partitions.  I think this is because the SSD on the macbook was configured with core storage, which the bootcamp NTSF drivers don't support

     

    I have a 5K iMac that doesn't have core storage, and I can see my Mac partitions just fine in bootcamp. 

    To check if your drive is partitioned under core storage go to Terminal and type "diskutil cs list".  If it says "No CoreStorage logical volume groups found", then you don't have core storage.

     

    Just wondering, is apple not enabling CoreStorage on all their new macs?  Are all the iMac 5K configured with core storage off, but Retina Macbooks come with it on for some reason?

    CS is the default beginning with Yosemite. It is mandatory if you use FileVault2 or have a Fusion drive. If you do not use FV2, and your CS is revertible, you can revert to HFS+ which will be visible and read-only on the Windows side.
