It’s not just music applications that are having issues. This has “broken” a number of music tools, such as Traktor and Rekordbox. The underlying XML database and associated XML file no longer exist to index a local music collection. If you do any kind of audio mixing or heavy music work using iTunes and third-party software, you will likely run into problems. In macOS Catalina, Apple has done away with the iTunes app, splitting its features into three separate apps: Music, Podcasts, and TV (coming later this fall). While there are some interesting new features in this OS, like SideCar, Catalyst, increased security, and Apple Arcade, there are a number of things that either just won’t work or will present problems.
(As a general rule, waiting until the first set of OS updates are released allows Apple to fix initial stability problems and bugs before the OS even makes it to your machine.) Information Technology Services cannot yet support Catalina on University-owned Macs until several issues have been resolved, followed by further testing. As with most OS releases, we strongly recommend that you wait and not upgrade your University-owned Mac. Apple’s latest release, macOS Catalina (10.15), has what Apple admits are “major issues” and we have a variety of concerns.
