How can I verify and troubleshoot changes in the Mac proxy settings?

Solution

To troubleshoot common Mac scenarios, verify the Mac proxy settings. For example, after installing Fiddler Everywhere on a Mac, Fiddler Everywhere may not be able to start capturing traffic. This issue may be caused by various reasons and, therefore, may require troubleshooting.

To troubleshoot this issue:

  1. Reset the Fiddler Everywhere settings to their default values.
  2. Close Fiddler Everywhere.
  3. Verify the Mac proxy settings.
  4. Open Fiddler Everywhere.
  5. Verify the Mac proxy settings.

Verifying the Mac Proxy Settings

Go to the Apple Mac proxy settings in System Preferences > Network > Advanced. Note that each network adapter will have proxy settings. For example, if the Internet is available through an Ethernet port and a WiFi connection, you will see two adapters each with separate proxy settings.

The default settings of Fiddler Everywhere will Act as a System Proxy on Startup. This will turn on Configure the Proxy Settings Automatically when Fiddler Everywhere is running, and will clear the Configuration when Fiddler Everywhere is closed.

When Fiddler Everywhere is closed with the default settings, the System Proxy Settings will look like the following.
