Fiddler not capturing after installing MacOS Ventura

Fiddler was working fine until I installed MacOS Ventura. Just before the install it was working, not anymore right after the install. I don't believe anything happened in between (e.g. installed something, updated another settings, etc.).


I tried reinstalling Fiddler and the root certificate, but nothing helps. 


Fiddler start fine. I can make requests. But no traffic is captured. When I enable traffice capturing (the switch) nothing seems to happen. System proxy is also not updated. You can find a short movie of the behavior enclosed.


Anyone else with this issue? Any ideas I can try? Is this a Fiddler/Ventura bug?


Please help. I am just about to give an internal knowledge share about this product

Hello Peter,



Thank you for reporting the issue related to Fiddler Everywhere not working on the new macOS Ventura. 


I can confirm that the Fiddler team pinpointed the issue, and we are currently working on fixing the problem caused by a breaking change in the macOS core network tooling. Once the fix is thoroughly tested and approved, we will immediately release it through a public patch version - stay tuned for more information about when we plan to release the patch.
