Fiddler everywhere crash immediately upon start

crash on 3.0.1 or 2.2.0

macOS version 10.14.6

was able to launch the app before...

suddenly it doesn't work.


tried reinstall, clean install, rollback to 2.2.0


and the log directory is empty, the only log I got from console:

Hello Goncc123rr,


Your logs indicate that the used OS is macOS Mojave which is not officially supported by Apple anymore (Apple only officially supports the three most recent versions of macOS, currently 10.15 Catalina, 11 Big Sur, and 12 Monterey). Try to update your OS and then retry running Fiddler Everywhere. 

Hi Nick,


Thanks for quick response,

this does not make sense because I could open Fiddler with the same OS before.

The older versions of Fiddler Everywhere used an older version of the NET framework, which was utterly compatible with Mojave. Our tests with the beta versions of NET6 alongside Mojave also worked very well. However, the final version of the framework is most likely the ones that are no longer compatible. Given that we provide support for the officially supported versions listed from Apple, I would still recommend an OS upgrade.
