I'd downloaded chromedriver some time ago and already used it in my project - I'd been able to run the same tests previously - but the recent system update resulted in this file being newly flagged. Impact: a malicious application may bypass Gatekeeper checksĭescription: a logic issue was addressed with improved state management. As described in the Apple security updates release,

In the latest update, I saw there had been an update to the Gatekeeper logic to make it more robust. By default, downloads from the Apple store or with a valid Apple developer certificate are allowed. MacOS has security checks run via software called Gatekeeper, which checks any downloaded apps or executables. If not, here's what I did to resolve this issue. It may be possible to 'open anyway' from your Security & Privacy settings. MacOS cannot verify that this app is free from malware.

“chromedriver” cannot be opened because the developer cannot be verified. Having updated MacOS, I found I couldn't run the tests in my project due to the chromedriver file being quarantined. I've been learning Selenium WebDriver, which allows me to automate tests by using WebDriver's chromedriver tool to navigate the Chrome web browser automatically.
