I have installed Mono 5.2.0 for OSX and MonoFiddler 4.4.8.4 Built for Linux, and I also run mozroots —import —sync for HTTPS, however, when I run mono Fiddler.exe , it said "NameError: name 'lldb' is not defined" 
"Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application."    

and the mono process exited unexpectedly!

and I want to know why..

Hi,

Why are you trying to run Fiddler built for Linux on OSX? Go grab the Fiddler built for Mac and use it instead. Also, since you are using Mono 5.2.0 you have to pass --arch=32 to the mono command. You can find more information here.

[quote]pass --arch=32 to the mono command[/quote]

This helped, however overall user experience is awful, the only real workaround for me is to execute Fiddler in Parallels Coherent mode and use some tricks to redirect HTTP traffic via Parallels network.
