Apple's big WWDC keynote this year lasted nearly two hours, and included news spanning the Apple ecosystem. Announcements included iOS 18, iPadOS 18, watchOS 11, macOS 15, and Apple Intelligence, the company's version of AI.
If it's been a few years since you upgraded your Apple Watch, the new watchOS features Apple showed off at WWDC this week may not work with your smartwatch.
IOS 18 will be available for all iPhones that run iOS 17. Apple will stop supporting some iPads, some MacBooks, and some Apple Watch models with software upgrades this year.
