Apple unveils 'Glow All Out' wallpaper ahead of WWDC 2026: How to download and what to expect from Apple’s biggest event of the year

Apple is all set to host its annual developer conference WWDC 2026. Apple has announced that WWDC will start with a keynote presentation on June 8 at 10.00 AM Pacific TIme and 1 PM Eastern Time. Now ahead of Apple's biggest event, the company has dropped a fresh teaser for its upcoming conference unveiling a new ‘Glow All Out’ wallpaper and curated Apple Music playlist. The release comes just days before the keynote event which is expected to showcase major updates across iOS, macOS, and Apple’s expanding AI ecosystem. The Glow All Out wallpaper features Apple’s signature vibrant gradients, designed to match the conference’s theme. Greg Joswiak, senior vice president of worldwide marketing shared a wallpaper on social media platform X (formerly known as Twitter) encouraging fans to download and set it ahead of the keynote. The design reflects Apple’s tradition of using bold, colourful visuals to build excitement around WWDC.Apple has made the wallpaper available for free across devices. Users can download the wallpaper directly from Apple’s WWDC 2026 event page via links shared on social media. The wallpaper is optimised for iPhone, iPad, and Mac making sure seamless integration across the Apple ecosystem.Alongside the wallpaper, Apple has released a WWDC 2026 playlist on Apple Music. Curated to match the “Glow All Out” theme, the playlist features upbeat tracks meant to capture the energy of the developer community and set the tone for the conference.On the software side, WWDC26 will preview the "27" generation of Apple's operating systems—iOS 27, iPadOS 27, macOS 27, watchOS 27, and visionOS 27. The biggest draw is expected to be a long-overdue Siri overhaul. Apple is reportedly building a chatbot version of Siri—codenamed "Campos" internally—that would put it in direct competition with ChatGPT and Gemini. It would retain Siri's familiar trigger mechanism but add a full conversational interface on top.iOS 27 is otherwise shaping up to be a Snow Leopard-style release: heavy on stability, lighter on splashy features. Apple engineers are reportedly rewriting chunks of the OS to squash bugs and improve battery life, even on older iPhones. On the Mac side, macOS 27 will drop support for Intel-based Macs entirely, making Apple Silicon a hard requirement going forward. Rosetta 2, however, sticks around for one more cycle.Hardware isn't off the table either. The Mac mini and Mac Studio are both due for M5-series chip upgrades, and WWDC is a plausible landing spot if Apple doesn't release them before June. The M5 Pro and M5 Max bring up to 30% faster CPU performance and 50% faster graphics over their M4 predecessors.Apple VP Susan Prescott called WWDC26 "one of our best yet"—standard fare, but the Siri chatbot alone should make June 8 worth watching.
