Today the latest build for chrome browser version got installed automatically which is now 54.0.2840.71 m (64-bit). I am unable to drive the browser using the latest Chrome
The whole chain needs to be aliged to version which support what they control: Selenium -> Selenium Chrome Driver -> ChromeDriver -> Chrome.
Regarding Chrome Driver:
See the other answers for traditional installation.
For Apple / MacOS with Brew, you need to:
Upgrade ChromeDriver through brew:
brew cask upgrade chromedriver
The version of chromedriver is nowadays aligned with Chrome, so Chrome 80 comes with ChromeDriver 80. It seems to appear in Brew very soon after Chrome.
Regarding Selenium ChromeDriver: Don't forget to upgrade to the latest version of selenium-chrome-driver (along with the rest of Selenium deps) which knows how to operate the latest ChromeDriver.
