Upgraded to High Sierra and Bootcamp graphics and now I can't boot in Mac OS

How can I boot back into Mac OS?

I upgraded to High Sierra and ran it without issue. Later, I restarted into Windows 10 using bootcamp. Bootcamp had a graphics card update it wanted me to install. Once I updated that, I could no longer boot into Mac OS, only windows. How can I boot back into Mac OS?

Thank you for any help,

Hello artwheat,

It sounds like you need help booting back into Mac OS. I don’t blame you for seeking a solution - it’s important to have your device running the way you want. You’re in the right place to find a resolution.

Here's are some resources that can help:
