Apple killed iTunes in macOS Catalina, which begs the question: how will I sync my iPhone or iPad with my Mac now?

Though Apple tends to do the weirdest of things at times but the company’s move to abandon iTunes completely in favor of three separate apps for music, movies and podcasts is a move many have decided to rally behind. Everything makes far more sense now. But same can’t be said for those who make use of iTunes to create backups, sync movies, backups and more.
