Does this use my mac's browser in headless mode? If yes, my current version of chrome is 76 and everytime i run the automation locally, it throws "SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 74
(Driver info: chromedriver=74.0.3729.6 (255758eccf3d244491b8a1317aa76e1ce10d57e9-refs/branch-heads/3729@{#29}),platform=Mac OS X 10.13.6 x86_64)"

Work just fine.

Thank you.
