    I installed the Fiddler on the Mac.

    Following the instructions, when I enter

    mono Fiddler.exe

    I get the following error message:

    -bash: mono: command not found

     

    Any ideas?

    Thanks,

    Michael

    Hello,

    It looks like mono didn't install successfully. It should be in /Library/Frameworks/Mono.framework/. Is it there?

    Yes, it is there. I see the Versions folder and its subfolders 4.6.1 and Current.

     

    But now I get another error message:

    Cannot open assembly 'Fiddler.exe'

    Hello,

    How did you make Mono work? Are you sure that your installation of Mono is fully functional? Can you run other Mono applications?

    Hi,

    I had same issue, but i figured it out by:

    run "/Library/Frameworks/Mono.framework/Versions/<your fiddler version>/bin/mono Fiddler.exe" from your unzipped fiddler directory.

    Hope this will help.

    If anyone hits this, before you do anything too drastic I would suggest trying to quit terminal (make sure dot goes away) and re-open.  I believe the installer modifies the path on your .bash_profile but it is not re-sourced so mono is not in your path.  I was able to quit and reload the terminal which allowed mono to be found.  Hopes this helps someone else out.

    I get a mono error when I execute:

     /Library/Frameworks/Mono.framework/Versions/Current/bin/mono ~/bin/Fiddler.exe

    It gives an alert "mono quit unexpectedly", and an execution error and stacktrace:

    WARNING: The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at all
    Stacktrace:

    Hello,

    You have to run Mono in 32-bit, because "The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at all". Please, use the following command in order to start Fiddler:

    mono --arch=32 Fiddler.exe
