Description

How can I verify and troubleshoot changes in the macOS proxy settings? How can I confirm that the Fiddler Everywhere is successfully set as a system proxy?

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 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. Re-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.

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