What to expect from WWDC 2019: new Mac Pro, iOS 13 with Dark Mode and updates to core apps, macOS 10.15 with Marzipan apps, and 31.6-inch 6K pro display
Apple's big Worldwide Developers Conference (WWDC) keynote is happening on Monday, June 3rd, and this year looks to be more consequential than most.
Context & Ripple Effects
Apple set the stage in March when it confirmed WWDC 2019 would run June 3-7 at San Jose's McEnery Convention Center, and this preview consolidates the rumor set ahead of Monday's keynote: a new Mac Pro, iOS 13 with Dark Mode, macOS 10.15 carrying Marzipan apps, and a 31.6-inch 6K pro display.
The arc here runs back through The Verge's prior WWDC previews — 2016's Siri SDK and Siri-on-the-Mac expectations, then 2017's spec-bump-and-Siri-speaker slate — which were incremental OS years. What makes 2019 read as more consequential in this coverage is the combination of a pro-hardware reveal with Marzipan, Apple's bridge for running iOS apps on the Mac.
First-order effects
- Developers attending the keynote get their first official look at Marzipan tooling in macOS 10.15, the mechanism that lets them port iPad apps to the Mac rather than maintaining separate codebases.
- Creative-pro buyers finally have a current-generation Mac Pro and a matching 31.6-inch 6K display to spec against, ending the wait that has defined Apple's pro desktop line.
Second-order effects
- If Marzipan ships broadly, the Mac's software catalog shifts toward iOS-derived apps, pressuring Mac-native developers to justify platform-specific versions of their products.
- A modular Mac Pro paired with a first-party 6K display pulls high-end monitor purchases into Apple's own accessory lineup, competing directly with the third-party displays pro users currently pair with Macs.
Third-order effects
- Dark Mode arriving in iOS 13 alongside Marzipan points toward a single design language and shared app economy across iPhone, iPad, and Mac — the structural endgame being one developer platform with two hardware surfaces.
- If the pattern from 2016 through 2021 holds — each WWDC layering the next OS iteration onto the last — Apple's annual June cadence becomes the fixed point around which its entire developer and pro-hardware roadmap is planned.
The trend: Apple is using WWDC to converge iOS and macOS around a shared Marzipan app model while re-entering the pro hardware market with the Mac Pro and 6K display.
