Apple recently confirmed that along with the arrival of macOS Catalina comes a major problem involved with the end of support for iTunes. This problem, a report stated, will affect a particular group of MacBook users.

Cupertino tech giant Apple recently released macOS Catalina, the latest macOS version for Macs, iMacs, MacBooks and MacBook Pros. The latest macOS version brings a slew of new features, but also removes one of the most used and longest-running apps in Apple’s ecosystem: iTunes.

Apple told The Verge that along with the removal of iTunes also comes the end of XML file support. The new Music app has a new library format, which means that Mac, MacBook and MacBook Pro users who have a lot of music stored on their iTunes library won’t be able to play this music anymore.

This problem, according to Forbes, will greatly affect DJs who use their MacBook Pros when they perform. XML file support is a popular tool DJs use to organize their tracks and playlists.

iTunes also allows DJs to work seamlessly using other apps. The “Share iTunes Library XML with other applications” option, for example, allows them to transmit music and playlists with other useful apps like Pioneer DJ’s Rekordbox and Traktor. iTunes, with XML file support, is a very powerful tool DJs use in gigs and performances.

DJs who update to macOS Catalina, then, will find the new version troublesome, at least for now. The new Music app will not be able to communicate with other DJ apps, and will cause DJs and other professionals that are heavily dependent on XML files some considerable trouble. Worse, those who fail to backup might get their work erased simply by updating to Catalina.

That said, Apple recommends all DJs and XML file-dependent individuals to wait for third-party developers to release compatibility updates to Catalina, Fact Magazine noted. Some apps like Algoriddim’s djay and Virtual DJ are compatible with Catalina.

Rekordbox, on the other hand, doesn’t have a version or beta that has support for Catalina. “We will finish our initial research by the end of October 2019,” Pioneer DJ said as per DJ TechTools, “and will post updates on our progress when we know more.”
