Yes, had same issue after update to 15.4 (Sequoia) the OS of MacBook Air, EyeTV was only "loading..." endlessly.
I have started downloaded from the official website the "EyeTV Reporter" app for to uninstall first EyeTV application and all other components and files related to EyeTV,:

then installed the Senitel app for Mac as per the URL link provided in the forum then installed the EyeTV4.0.0_8528 version, used Senitel app, dropping EyeTV app in quarantine then to self sign and worked like a charm. That forum is great! Thank you for the tip!
