Have you tried syncing your iTunes to an IOS 14 device?After a year of thinking I was better off with Mojave, I decided to finally update my 2012 Mac Mini to Catalina. This forum thread scared me out of updating due to all of the problems with the Apple Music app. I use iTunes extensively in my day job, managing a music library of over 100,000 tracks. I don't bother with album art or any cloud features, nor do I subscribe to Apple Music, but I still have concerns about bugs that could potentially mess up the library. I'd be pretty screwed if a track magically disappeared, granted I do keep backups. And I am glad to hear the column browser made a return and Doug's AppleScripts can still be used, though I still worry!
Thanks to your suggestions, I updated to Catalina and installed iTunes with Retroactive. I haven't even tried the Apple Music app, but my library loaded up in iTunes just fine as if I were on Mojave. I also feel like iTunes is running a bit faster for me on Catalina. So it looks like I'm all set for the time being! I do hope the Apple Music app will eventually be improved so I can move my large library to it. If any of you have the same concerns I do, Retroactive will solve your problem!
*Edit* I do have a question though. If I open the Apple Music app, will it automatically load my iTunes library? I'm thinking about using Music for my own personal music collection while keeping my work library exclusively linked with iTunes. I know I can hold Option when starting Music to start a new library, but I guess what I'm asking is will Music create a separate library file without attempting to import or overwrite my existing iTunes library?
Scanning all sites and forums I can find, I see no solution for syncing an IOS 14 device to get iTunes files from a Mojave or earlier device to the 14 device without destroying or losing iTunes files and artwork. Sync on iTunes is refused without upgrading OS.
Looks like Apple really serious about forcing the world to go to Apple Music.
