As with previous years, Apple is relying on a lottery system to address demand for tickets.
That's because Apple is expected to introduce universal apps that would run across Macs, iPhones and iPads.
iOS and macOS aren't the only game in town for Apple. The McEnery Convention Center will once again be home to Apple's developers from across the world.
Despite being developer-focussed events, these events are significant to everyone else as well because it's at these events that Apple announces updates to the software that powers its iconic devices. Apple needed to talk up the HomePod so that developers could start working on optimizing their apps for the Siri-powered speaker in advance of its release. This year, Apple will unveil iOS 12 and we could see the new Apple iPad Pro slates that feature an edge-to-edge display, the TrueDepth Camera and Face ID.
