From your website, I downloaded mono framework and fiddler-mac in SnowLeopard.

After installing mono and doing /Library/Frameworks/Mono.framework/Versions/4.6.2/bin/mozroots --import --sync, I extracted the zip file in the document folder. In terminal, cd to the folder and type mono Fiddler.exe, then following error occured:

exception inside UnhandledException handler: The type initializer for 'Fiddler.CONFIG' threw an exception.

I have the exact name issue where it crashes immediately after calling mono Fiddler.exe. I first tried in /Applications, then move the app to ~/Downloads. I'm running El Capitan (10.11.6).

 

Tsviatko, any ideas on how to resolve this?

 

Thanks.

Hello,

Sorry about the late reply.

That is a pretty weird problem. Which version of Mono do you, guys, have installed? Chris, are you certain you get exactly the same error?

Hello,

Looks like your installation of Mono is not complete. libgdiplus.dylib seems to be missing. Please, make sure this library gets installed.

Well it looks like the brew installation really misses libgdiplus.dylib. It seems to be missing from other third-party installations, too. 

So, please, install the official Mono packages.

Looks like the version 4.6.1.5 that brew installs does not have a libgdiplus.dylib file. I checked another version of mono on my machine (version 4.8) and I see the libgdiplus file. So, I ended with the following:

/Library/Frameworks/Mono.framework/Versions/4.8.0/bin/mono Fiddler.exe

since brew wouldn't install a RC version of Mono.

Hi Govind,

You have to pass --arch=32 to the mono command. This is needed because the 64-bit version of Mono does not support WinForms.

If you installed mono with homebrew, try this

```sh

brew cask install mono-mdk

 

# and... PATH setting in your profile (ex ~/.bash_profile or ~/.zshrc)

export MONO_HOME=/Library/Frameworks/Mono.framework/Home

export PATH=[....previous path setting]:$MONO_HOME/bin

 

# mono run with argument

mono --arch=32 Fiddler.exe

```

Hi Rahul,

The command should be "mono --arch=32 Fiddler.exe" (notice the 32  in the --arch parameter).

As a side note - have you tried the new Fiddler Everywhere?

Alexander

Hi Alexander, 

using mono --arch=32 Fiddler.exe command running on default port: 8888, however the problem here is registering the FiddlerRoot.cer file and even Trusting this certificate, mac doesn't capture the required Traffice from the Browser?

will appreciate a solution here so that , we don't spine a docker image of windows and run this useful tool everytime, so would like a solution to this problem. 

We are using your Edge license.

Rahul.

Hi,

HTTPS decryption does not affect the traffic capturing, i.e. if Fiddler does not capture traffic from application X configuring HTTPS decryption would not fix it. Would it be possible to share a screenshot of the proxy settings tab for your active network connection?

Alexander

Hello,

Yes, I see the problem. By default on startup Fiddler changes the proxy settings to point to 127.0.0.1:8888. In order to do so, Fiddler needs elevated privileges and asks for password. Was there a password prompt on startup?

Regards,
Alexander
