Unable to use chromedriver following OS upgrade Error: “chromedriver” cannot be opened because the developer cannot be verified.


Updated OS is Catalina, version 10.15.2 (19C57). 

chromedriver was working fine prior to the OS update. I've tried both the local chromedriver that was working previously as well as a newly downloaded copy.

What can I do to get this running again?
Open system preferences, security and privacy, General tab and click "Open Anyway" or similar. It will ask for root password.

If that doesnt work, try the following, courtesy of user365987

Open a terminal window and run this command to find the location of chromedriver:

which chromedriver



Once you find the location, open that directory with MacOS Finder.
Ctrl + Click the chromdriver file.
Select Open on shortcut menu.
Click Open on the dialog.
