I am on macOS Catalina 10.15.7.
After installing Fiddler Everywhere, i am able to start and login.
However, it's not capturing any traffic. I've tried with chrome and firefox.
After doing some search (
https://docs.telerik.com/fiddler-everywhere/knowledge-base/troubleshoot-mac-proxy-settings), it looks like Fiddler is not updating the proxies after it is opened.
I have also tried install & trust root certificate.
