I am trying to reverse engineer a protocol which uses HTTPS exclusively.

On Windows I was using oSpy to view the plaintext of local SSL packets, but for MacOS I have not been able to find an equivalent.

Is anyone aware of a tool which allows you to view the plaintext of HTTPS communications on a Mac?

Charles can do this according to the description.

It might also work with HTTP Scoop, there is a section on the support page about it.
