Fiddler for Mac OS X: A Game-Changer for Web Developers

The wait is finally over! We are thrilled to announce that we have successfully ported the latest version of Fiddler to the Mono Framework, making it possible to run Fiddler natively on Mac OS X. This beta release marks a significant milestone in our journey to bring Fiddler to the macOS platform.

With Fiddler for Mac OS X Beta, you can now inspect traffic, set breakpoints, and 'fiddle' with incoming or outgoing data with ease. While Fiddler for Windows is capable of being used as a proxy for apps running on OS X, there's immense value in having a native build that allows web developers to work seamlessly on their preferred platform.

Over the years, we have received numerous requests from our user community to provide a Fiddler build for OS X. Today, we are proud to deliver on this promise and invite you to try out Fiddler for Mac OS X Beta. Your feedback and suggestions will play a crucial role in shaping the future development of Fiddler.

Known Issues

During testing, we have identified some known issues that may affect your experience with Fiddler for Mac OS X Beta. Specifically, when 'decrypt HTTPS traffic' is enabled, Safari may encounter difficulties accessing certain well-known sites such as Facebook, Twitter, and GitHub. This issue appears to be limited to Safari and only occurs when you stop at the site before opening Fiddler. However, restarting or refreshing the impacted areas often resolves the problem.

Additionally, some users have reported issues with resizing windows and elements within them. We are aware of these problems and will prioritize addressing them in future updates.

We are excited to bring Fiddler to the macOS platform and appreciate your enthusiasm for this new release. Your feedback is invaluable in helping us refine Fiddler for Mac OS X Beta, so please don't hesitate to share your thoughts on our Fiddler forum.
