Can't get my MacBook to switch back Mac os from windows 10

I recently installed windows 10 pro education n edition through boot camp. I have a MacBook Pro 2016. I cannot get back to Mac OS X. I've tried multiple times restarting/powering off computer and pressing down the option key. It does give me the icon to click to switch to Mac but every time I click on it, it restarts and gives me a symbol with a circle and slash. And the computer still windows mode. I've also tried the icon panel in the bottom right which I can open up bootcamp control panel. It gives me a choice to restart in Mac or windows. I choose Mac and the same thing happens. When it restarts, I get that circle with a slash and I am still in windows. Please do help if you have an answer. Thanks!!

If you see a circle with a slash, your macOS system folder is likely damaged.

Based on your current circumstances, you’ll need to use another Mac in order to repair yours. Connect an empty flash drive to the other Mac and create a bootable installer using the steps in this article:

Make sure your flash drive is named MyVolume before using the Terminal command.


Once you’ve made a bootable installer, connect it to your malfunctioning Mac and hold the Option key while turning it on. Release when you are presented with various startup disks to choose from. Use the arrow keys to select Install macOS High Sierra, then hit Return (Enter). Your Mac should proceed to boot Recovery Mode using the flash drive. When the Utilities menu appears, choose Reinstall macOS. (You will not lose your data.) Select Macintosh HD as the target volume and let the installer repair your Mac. If all goes well, your Mac should restart to the login screen when it’s done (or to a setup assistant if you wiped your hard drive).
