Hey guys, lately my MBP keeps booting into my Windows 10 partition. I have chosen Mac as my default in Boot Camp Control Panel and still whenever I power on, it goes right into Windows. On the Mac side, I have also chosen Mac as my default in the "Startup Disk". Everytime I boot into Windows, I notice that my choice on the Mac partition to use Mac as my default gets erased in the sense that it is as if I didn't make or confirm my choice (both choices are grey-ed out). Anyone have any ideas as to what's going on? This only started after a "graphics driver update for bootcamp" in Windows 10. Thanks guys!

Could you try hold Alt on startup and select Macintosh HD with the arrow key. Hold CTRL. The arrow icon will then change. Press Enter.

Does it now boot into Macintosh HD by default or does it still exhibit the same issue?

Thanks for the reply! That works only if I boot into Mac. If I boot into Windows and restart, it will automatically boot me into Windows. Holding down the alt key after that on startup does nothing and I go straight into Windows again. I have to restart into Mac from the boot camp control panel to have Mac start up as my default.
