Running 4.0.0 (8526) on an Intel 2018 (i7) Mac mini with the beta OS, eyeTV crashes saying it is unable to find the library /System/Library/Frameworks/FWAUserLib.framework/Versions/A/FWAUserLib.
Interestingly, I'm unable to find a file at that path under Monterey either.
Hope this isn't the end of the road for eyeTV on Mac.
NB No, I've not bothered to submit a bug report as it appears Geniatech don't read them anyway.
