Windows 10 - could not locate the macOS boot volume
I recently installed windows 10 via bootcamp, but am getting the error "could not locate the macOS boot volume" when using the Bootcamp tray icon to restart my MacBook into macOS. I'm able to use the option key during boot to select startup OS, and both windows and macOS work.
The AppleOSSMgr service is running as expected.
At a loss of what else to try, any help greatly appreciated!
MacBook (Retina, 12-inch, Early 2015), macOS High Sierra (10.13.3)
