Hi all,

I have a question for any other Bootcamp users out there. I've used Windows on my Mac via Bootcamp for many years; it is not unfamiliar to me. However, after recently upgrading to my new MacBook Pro (15-inch, 2017) I'm encountering a small but mildly irritating bug.

When in Windows, normally you can simply click on the Bootcamp control panel in the taskbar and click restart in macOS and there you go, MBP boots up automatically in macOS. However when I do that now, since upgrading to my new computer and setting up Bootcamp, it says that it cannot find the macOS volume. Similarly, when I go to view the volumes from the Bootcamp control panel in Windows, only the Windows partition shows up (and of the proper size, I might add.).

In macOS, however, when I go to Bootcamp settings I can clearly see both volumes, and can select which I want to boot in to on restart - macOS or Windows.

As a result, whenever I boot in Windows, I have no choice but to manually boot into macOS - restart and hold down the option key. The strange thing is that again, like in macOS, both volumes show up - Windows and macOS. It is only within Windows itself that the Bootcamp control panel cannot "find" the macOS partition. My first troubleshooting thought would be to think that I overwrote the macOS partition when installing Windows, but I know that I didn't and either way if I did that I wouldn't be able to manually boot into macOS anyway.

Does anyone have any suggestions on how to resolve this? Admittedly it isn't a break-fix as I have a workaround solution, but instead of every time I use Windows having to be prepared upon restart to hold down option at the right time it would be nice to have the BC Control Panel work as designed and be able to simply click on restart in macOS.

Thanks for any suggestions. Really hoping to avoid having to delete my Windows partition and start over as I've installed a lot of things already and it'd be a pain in the ass to have to do so again and fight with Windows support to get my activation key working again since it's been used.

Cheers!

I read somewhere that it is a problem with APFS, since the Bootcamp software in Windows only supports booting to HFS+ partitions up to now.

I am having the same issue... I am not even able to open the Bootcamp utility at all in Windows. I am using Windows 10.

Thanks for the information.

Strange - hopefully they release a software update soon. When I was finished installing Windows 10, the Bootcamp setup assistant installed the BC Utility/control panel and related drivers, Apple Software Updater, etc., and I was able to use my Magic Mouse 2 and Keyboard properly - the only thing that seemingly is "wrong" is that boot in macOS and the macOS volume missing when I view the volumes from within Windows.

I suppose I'll just have to keep doing the manual reboot + option-select volume workaround for now until (hopefully) a software update is released to the Bootcamp utility and/or macOS to resolve this.

Cheers
