Hello Michael, thank you for bringing this up.

From what I’ve read, you don’t have to import the certificates manually anymore, Mono does this for you (the changelogs from version 4.8.0 https://www.mono-project.com/docs/about-mono/releases/4.8.0/ and 5.16.0 https://www.mono-project.com/docs/about-mono/releases/5.16.0/#client-certificate-support) mention something in this direction.

I will remove that section from the article since it’s deprecated.

Are you currently running Fiddler on MacOS ? And did you have any difficulties in capturing https traffic with this tool?

Thanks again!
