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

Hi rollercoasta, I con confirm you that even with the mac os sierra update, I didn't see the mac os partition on windows. I had to install paragon HFS plus for windows. And now everything works as previously. I see my bootcamp partition on mac os sire and I also see my mac os partition on windows bootcamp (but with a third party software paragon hfs plus for windows).

If you are using anything other than the BC/Apple supplied AppleHFS.sys/AppleMNT.sys to see a JHFS+ OS X partition, it does not address the OP. Windows 1511_1 and 1511_2 work, but 1607 and any other subsequent ISO release does not work.

OSX has built-in NTFS read-only (by default) driver.

Anyone tried the latest Windows 10 update?

KB3200970 (Anniversary Update 1607) Build 14393.447

That is released 3 days ago.

I wonder if this update fixed missing macPartition issue.

djpenn has been testing releases diligently. He may have better insight. It is very rare for Windows to fix such driver issues and Apple has no interest in fixing them either as they march towards CoreStorage as default.

I have the 14393.447 up and running - no change.

Though MS had announceda fix already in Septembre, I wouldn't mind converting my HD into CS either.

But there's no Bootcamp-CS-driver available yet from Apple - afaik.

So, for the time being, we're apparently dependant on Third-Party-Software.

Thank you for your posts - looking forward to any news on the OP 🙂

The so-called 'fix' is broken. Converting your OS X Partition to CS will stop third-party drivers from working with JHFS+. There is no likelihood of a BC/CS driver, unless consumers threaten to stop buying Macs to run Windows. CS was released in 2011 under OS X Lion, and for the last 5+ years, if Apple wanted to write a CS driver for Windows, they already would have written one.

Yesterday after the mac os sierra update, I was able to see the bootcamp partition on mac OS. But today I cannot see anymore the bootcamp partition... Strange.... But I still can see the mac partition on windows with paragon HFS plus for windows.

Do you have a third-party NTFS driver on the OS X side?

This is third-party software, not the native BC drivers. Users may not want to spend money to buy a third-party product.

I was having the same problem at first initially and then again after a more recent update, but I am now running 1607 version 14393.4979 (release preview)on a mid 2010 Macbook Pro and can access the partition. In connection with that issue and a separate problem I had booting OSX at all, I downloaded the Paragon trial version. After I had installed that trial version, before I had even restarted for it to actually take effect, suddenly my Mac E partition showed up again via Explorer without me even needing to login to Paragon. So it seems like somehow something that happened during that install process made it visible to Windows again without even needing to use the program itself. And it's definitely via Windows -- other applications such as Real Player are also able to access music files on that partition. Hope that helps somebody!

hey mate, THAT's News 🙂

I've reverted to 1511 just yesterday- because I thought nothing would change anymore. But now - maybe I'm gonna go for 1610 once again 😀

Before I start - could you just state if you can also see your macOS-drive in your windows-explorer again?

It seems to be a Microsoft-Problem then...

Thanks for sharing! 😀

A Restart is not absolutely necessary. As a test remove Paragon, reboot to ensure that there are no Paragon DLLs in use and then test again. Paragon also uses the MBR, which is not the case on 2015 and later Macs.

I don't know about the MBR (mine is definitely an older Mac), but I am definitely accessing the files via Explorer and they are also accessible via other applications such as Real Player. I do not have to open Paragon and it's also showing up in Disk Management where it wasn't before.

A 2010 Mac is uses an MBR to support Windows. If you upgraded from a W7/W8.1 installation it should be an MBR/legacy BIOS installation. Can you remove Paragon and run the test?

Also, the program isn't running and it is still working. So even if it's Paragon that triggered it, I hope it continues working even after the trial theoretically expires.
