Troubleshooting

Troubleshooting “chromedriver” Not Opened

If you get this error message:

Apple could not verify “chromedriver” is free of malware 
that may harm your Mac or compromise your privacy.

Then you need to adjust your system settings:

• Apple menu -> Settings -> Security & Privacy -> General

• See the entry that says: "chromedriver" was blocked to protect your Mac.

• Click the button "Allow Anyway".

Troubleshooting "This version of ChromeDriver …"

If you get this error message:

UnhandledPromiseRejectionWarning: 
SessionNotCreatedError: session not created: 
This version of ChromeDriver only supports Chrome version …

Then you may need to harmonize your Chrome browser app and your Chrome webdriver.

To update your Chrome browser app:

• On your computer, open Chrome.

• At top right, tap the "More" icon, which is 3 vertical dots.

• You see the "More" menu. If you see a menu item "Update", then choose it. If you don't see a menu item "Update", then you're on the current version.

To update your Chrome webdriver:

• Go to https://chromedriver.chromium.org/downloads

• Download the version that matches your Chrome browser app.
