Fiddler For Mac Os

While Fiddler for Windows can be used as a proxy for apps running on OS X, there is still great value in being able to run Fiddler on OS X natively. So we have ported the latest version of Fiddler to the Mono Framework which in turn supports OS X—and you can grab the beta bits today. Available for Windows as a download from the developer website. There are also beta versions available for Mac OS, and Linux. Is there a better alternative? No, there isn’t a better alternative to Fiddler. Wireshark and Firebug are potential alternatives. These two do not compare when it comes to functionality and usability.

Overview

I could not find a good walkthrough so here is one for you. Disclaimer: This is on the latest OS and Latest version of Fiddler Beta

Steps

Install Mono – You can do this many ways but I wanted to do Xamarin development so I downloaded and installed Visual Studio for Mac and installed Mono as part of that installation:

Download Fiddler – https://www.telerik.com/download/fiddler/fiddler-osx-beta

You did step 1 of the instructions on this page already if you installed Visual Studio.

Move the ‘fiddler-mac’ folder somewhere you have write access to. I chose my Applications Folder. Open in Finder:

and then just drag and drop it into Applications:

And here it is!

Next find the Terminal app in LaunchPad and run it:

Navigate to the Applications folder: cd /Applications/fiddler-mac/

Pre the instructions I ran this: mono fiddler.exe

And got this error:

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

Stacktrace:

at <unknown> <0xffffffff>

at (wrapper managed-to-native) System.Windows.Forms.XplatUICarbon.CGDisplayBounds (intptr) [0x00002] in <36fbc38531724d82b10aef6ebafea6e9>:0

And this error because I never ran/accepted the xcodebuild license : Agreeing to the Xcode/iOS license requires admin privileges, please run “sudo xcodebuild -license” and then retry this command.

To fix this I first ran: sudo xcodebuild –license

and then used the correct 32 bit command to run mono and fiddler: mono –arch=32 fiddler.exe

You next have to allow changes to your networking so you will be prompted:

And Fiddler will start running!

When you start capture, again you need to enter your password to reset the proxy.

Conclusion

Pretty simple but like I said, I had no luck finding a good workaround and the fiddler instructions did not have the sudo xcodebuild –license, nor the mono –arch=32 fiddler.exe commands

Drop me a note if you found this useful!

Switching to Fiddler Everywhere 1.0 broke my internet

On Mac OS Mojave.

Here is what I think happened:

1. I started an older version of Fiddler Everywhere (probably 0.5, but I'm not sure)
2. It asked for my system password to configure proxy settings
3. I got a download prompt about a new version
4. I Cmd+Q in Fiddler Everywhere (This typically would break internet. You have to properly exit in order to properly tear down the proxy settings.)
5. When I launched Fiddler again, it was the 1.0 version

• Rebooting does not fix this.
• When I exit Fiddler 1.0, there are no obvious or visible proxy changes in Settings > Network > Advanced > Proxies
• I tried to find a download link for v0.5.0, so I could reinstall that, start it and exit it properly. However, the download link for previous versions is not available.

Hello Greg,

I am sorry to hear that you are having issues with the new version of Fiddler Everywhere.

I noticed that you have already examined the Proxies settings and everything there appears to be in order. Nevertheless, since this is the most common cause for such behavior, I would ask you to try the steps outlined below before we look for other possibilities.

1. Make sure that Fiddler Everywhere is not running.
2. Open System Preferences -> Network.
3. In the Network dialog, select the active adapter (for example, Wi-Fi) and click Advanced.
4. In the new dialog (the settings of the selected active adapter), select Proxies and disable Web Proxy (HTTP) and Secure Web Proxy (HTTPS). Click OK to close the dialog and then Apply to save the changes.

Let me know if this helps.

Following those steps, I can confirm that there are no checked boxes in the settings (see screenshot).

~$ scutil --proxy

<dictionary> {

FTPEnable : 0

HTTPEnable : 1

HTTPPort : 8866

HTTPProxy : 127.0.0.1

HTTPSEnable : 1

HTTPSPort : 8866

HTTPSProxy : 127.0.0.1

It allows you to do many works without any hesitation. You can connect as many MIDI devices as you like and control onboard instruments independently. With this application, your all dreams come true in the music industry.

ProxyAutoConfigEnable : 0

ProxyAutoDiscoveryEnable : 0

SOCKSEnable : 0

}
But not here:

~$ networksetup -getwebproxy Wi-Fi

Enabled: No

Server:

Port: 0

Authenticated Proxy Enabled: 0

~$ networksetup -getsecurewebproxy Wi-Fi

Enabled: No

Server:

Port: 0

Authenticated Proxy Enabled: 0

How do I clear out the system wide proxy?

Greg,

This is strange, I haven't seen such behavior so far and I cannot reproduce the issue.

The commands that you are looking for should be:

However, the steps provided in the previous response should do the same. Can you confirm that you are doing this for the active adapter? Also, can you share an image of the Network dialog?

I'm not sure if my previous reply made it through..
Those networksetup commands don't improve my situation. I have attached a screenshot of the network settings dialog -- however, it's pretty standard.

Did you see my comment above about hard-exiting the previous version of Fiddler Everywhere? There was a known issue with that version which would leave your network settings in an inconsistent state.

The fix was to simply restart Fiddler and properly exit. On both start/stop it would request your password.

I believe that's what happened here. Can you give me a link to a previous version of Fiddler Everwhere for Mac?

Fiddler Free Download Windows 10

Hello Greg,

I am sorry to hear that the issue persists.

We are aware of the known issue that you linked, we are just not certain if installing an older version of the client will resolved the current problem. We are continuing to look for a resolution that does not involve installing an old version of the client. Nevertheless, I will still ask my colleagues if they can provide an older version of the client (v0.5.0) and if they do, I'll share it in my next reply.

Regarding your message not making it through, it did, but we are moderating posts that contain links, and that caused some delay.

Fiddler Trace

Greg,

You can use the following link to download version 0.5.0 of the Fiddler Everywhere client.

We identified some key changes between the two versions that would explain this behavior but we haven't made progress on finding an alternative resolution to this issue. Please, let me know if you were able to resolve the issue with the help of the older version.

Regards,

Garo Garabedian

0.5.0 didn't seem to help. I got the password prompt on startup & exit, but afterwards was still unable to access webpages.

However, I plugged an ethernet adapter into this Macbook Pro. That changed the output of:

and I was able to access webpages without Fiddler running.

Switching back to Wi-Fi:

I am cautiously optimistic that my machine is working again.
