I'm having trouble with the setup from the title.
When I launch the GUI, the app seems to recognise when Flirc is connected. If I open Device log and check "Enable IR Debugging" it seems that the keypresses from my remote (One for All URC 7935) seem to be registering with Flirc. However, I am not able to record any buttons.
So far I tried clearing the configuration, loading embedded firmware (I'm on v4.9.3), giving it Accessibility/Input Monitoring permissions in System Preferences, and plugging it into a different USB hub. None of it helped.
Could this all be the fault of Rosetta/Flirc app not being compatible with the new silicon? Or am I missing something?
