Ah so Apple is throwing you under a bus and instead of being disappointed with Apple you are here complaining about calibre, expecting me to do endless amounts of work trying to get approximately 100 dependencies and calibre itself to work on a whole range of OS releases from a trillion dollar company that cares nothing about backward compatibility or its users. I have better things to do with my time, thank you very much.
The version of Qt calibre 7 uses does not build without a certain version of xcode and xcode which is from the afore mentioned trillion dollar company requires certain versions of macOS to run.
Now it *may* be possible to build all of qt which includes all of chromium and all the other ~100 dependencies of calibre on Ventura in a way that it *might* run on versions of macOS older than ventura, but then I would need to run those versions and test on them those OSes and I am not going to do that. I can commit to supporting *current* macos releases which thanks to apple means about two releases at a time. Beyond that, feel free to build calibre and its dependencies yourself. Or maybe, just maybe, ditch apple for a company that cares about you.
