macOS 16 is Apple's upcoming operating system for Mac computers. It should be announced at the WWDC 2025 keynote ahead of a public release this fall. Apple is expected to expand itsApple Intelligence features, as it still needs to catch up with Google, OpenAI, and other top rivals. Heres everything you need to know about the upcoming macOS 16 operating system update.When will Apple announce macOS 16?If Apple follows the trend, it should announce macOS 16 during the WWDC 2025 keynote. The Worldwide Developers Conferencewill take place from June 9 to June 13. While it was previously held at the San Jose McEnery Convention Center in California, WWDC changed to a pre-recorded video presentation when the pandemic started. Now, the company also invites the media and developers to watch it from the Apple Park campus in Cupertino.As of now,Apple has already begun work on macOS 16.What will Apple call macOS 16?Rumors previously suggested Apple was teeing up macOS Mammoth, as the Cupertino company asked for a trademark extension of this name in 2021.Mammoth was rumored for 2021 when Apple unveiled Monterey and again rumored in 2022. For 2025, it's unclear what Apple will call macOS 16. Internally, the software is known as Cheer.Release datemacOS 16 is expected to be released in September 2025. Apple usually says the new system update will be available in the fall. However, the company has released it later in September for the past few years.Some rumors say Applewont make every major macOS 16 feature available all at once due to delays in Apple Intelligence.In fact, the most impressive features might not arrive until the first half of 2026.Rumored macOS 16 featuresSo far, the main rumored features are related to the expansion ofApple Intelligence and a major redesign. Heres what we know:A major redesign is comingBloombergs Mark Gurman reportsthat macOS 16 will fundamentally change the look of the operating systems and make Apples various software platforms more consistent. According to the journalist, Apple will unify the look of iOS, iPadOS, and macOS to deliver a more straightforward experience through the platform.With that, Apple will adjust the look of icons, menus, apps, windows, and system buttons. This is said to be the most significant redesign for the iPhone since iOS 7 and for the Mac since Big Sur. The primary goal behind these design overhauls is to bring more cohesion to Apples disparate operating systems.Besides that, in January,Front Page Techsuggested iOS 19 might get a redesign inspired byvisionOS, especially the Camera app, which several users find more confusing than ever. With several layers of interaction, some have suggested Apple might need to make the Camera app simple again, and redesigning it with the visionOS UI might be a possibility.Then, in April, John Prosseroffered yet look at what he thinks will be Apples iOS 19 redesign, afterBloombergs Mark Gurman said the leaked images were based on either very old builds or vague descriptions.Front Page Techhost Jon Prosser claims that Gurmans post actually prompted him to go back and take a closer look at the leaked iOS 19 build. When he did, he noticed that tapping on icons changed their shape. The icons suddenly became more rounded, similar to the look of the apps on visionOS, but not quite a perfect circle.Potential leak of iOS 19 redesign.

However, it would be interesting if the company made the design language of its major systems similar.Apple Intelligence has a long way to goApple doesnt have new Apple Intelligence features to introduce during themacOS Sequoia cycle. That said, the more advanced features will come in later 2025 or 2026 with macOS 16.According toBloombergs Mark Gurman, the first version of Apple Intelligence only offers domestic changes. However, a ChatGPT-like model is coming at a later date:These upcoming upgrades will make Siri easier to use on a day-to-day basis, but its not the brain transplant that the service really needs. Siri is still based on an outdated infrastructure AI models that have been overtaken by the technology used by ChatGPT and Googles Gemini. Siri hasnt yet been rebuilt for the generative AI age, even if Apple is trying to create the impression that it has.Its not just the LLM Siri chatbot that wont be released in 2026. Gurman says that a larger-than-usual number of features scheduled for macOS 16 (beyond the new Siri) are already postponed until spring 2026 (when macOS 16.4 debuts).In March, Apple announced that thelong-awaited personalized Siri experience in Apple Intelligence would be available in the coming year as the company delays the most important AI feature to date.Siri GPTAccording toBloombergsMark Gurman, Apples new version ofSiriwill employmore advanced large language models (LLMs)to allow users to have long back-and-forth conversations with the virtual assistant. Sources also claim that LLM Siri, as Apple employees have dubbed it, will be capable of handling more sophisticated requests even faster.Apple is currently testing the upgraded Siri oniPhones, iPads, and Macs as a standalone app, but the goal is to eventually replace Siri with the new version. Apple plans to introduce LLM Siri next year as part of iOS 19 and macOS 16 (codenamed Luck and Cheer).As was the case with Apple Intelligence this fall, the new Siri reportedly wont launch alongside the new hardware in 2025. Rather, Apple will announce it next year and start rolling out the upgraded Siri as early as spring 2026.The revamped Siri will rely on new Apple AI models to interact more like a human and handle tasks in a way thats closer to ChatGPT and Googles Gemini, Gurman explains in his report. It also will make expanded use of App Intents, which allow for more precise control of third-party apps. And the software will be able to tap into features from Apple Intelligence, such as the ability to write and summarize text.New emojiNew emoji coming to iOS 18.
