I have had a 4 TB external hard drive for years and used Monterey until November of 2022. I never had issues with my large music library prior to updating. After updating to Ventura things have never been the same. My computer often does not stream to my Apple TV. Play counts don't register. The software is extremely sluggish. Apple Music crashes occasionally. Very, very buggy all in all. I get the feeling that Apple doesn't want to support users with external hard drives and want to move users to their streaming service. I will never do that because no streaming service has everything that I have and I want control of my music library. This is really frustrating. Apple used to respect their users. I don't think they do anymore.
