Apple releases macOS Catalina with new apps Find My and Screen Time, as well as Music, TV, and Podcast apps to replace iTunes, Sidecar for companion iPads, more

Context & Ripple Effects
This release closes an arc that started when sources reported in April that the next macOS would ship standalone Music, Podcasts, and TV apps, and Apple made it official at its June announcement that it was breaking up iTunes into separate apps. A public beta followed in late June, with early impressions framing Catalina as the start of a cross-platform era via Project Catalyst.
Today's shipping release turns that plan into default software on every new Mac: iTunes is gone, replaced by Music, TV, and Podcasts alongside new Find My and Screen Time apps, and Sidecar lets an iPad serve as a wireless second display. The same-day reviews flag the trade-offs — Sidecar lands well, but Catalyst-built iPad apps are thin and security prompts are aggressive.
First-order effects
- Every Mac user upgrading loses iTunes as a single hub, with libraries split across Music, TV, and Podcasts and device syncing moved into Finder.
- iPad owners gain Sidecar, turning existing tablets into external Mac displays without new hardware, which strengthens the case for keeping both devices in Apple's ecosystem.
Second-order effects
- Desktop streaming rivals like Spotify now compete against a preinstalled, native Music app on the Mac rather than one bundled iTunes storefront, raising the bar for third-party clients.
- Developers face a fork in the road: Project Catalyst offers a path to bring iPad apps to the Mac, but reviewers finding those ports lacking means half-finished Catalyst apps could hurt more than staying off the platform.
Third-order effects
- If Catalyst matures, the historical separation between iOS and macOS app catalogs erodes toward a single Apple developer target, reshaping how Mac software is built and distributed.
- The iTunes breakup signals Apple's shift from monolithic media hubs to per-service apps, making each subscription — Music, TV, Arcade — its own surface inside the operating system.
The trend: Apple is dismantling its monolithic first-party apps into service-specific ones while converging iOS and macOS onto shared app foundations, with the iPad positioned as the connective hardware.
