Apple's most exciting WWDC 2021 announcements for iPhone, Mac and more

Apple's annual WWDC event is synonymous with software -- specifically, updates to the brawny platforms that power your iPhone, iPad, Mac, Apple Watch, home security cameras and more. Think of it as a sneak peek at the new tools your devices will be able to do, and as a summer buildup to the fall event when Apple is expected to unveil iPhone 13 and more.

True to form, Apple revealed upgrades to many of its operating systems, most notably iOS 15. Apple also introduced MacOS Monterey, previously known as MacOS 12, along with WatchOS 8 and iPadOS 15. (The rumored HomeOS, however, didn't make an appearance.) Developer betas of all Apple OS upgrades are available today, but the general public will have to wait for public betas to start in July, with wide releases likely coming sometime this fall.

In Apple's big keynote address, with CEO Tim Cook at the helm, the iPhone-maker also unveiled some new tricks for existing products such as FaceTime, iMessage and Apple Maps, a slew of new health features, updates to Siri and AirPods, and a new iCloud Plus service with enhanced privacy controls. The conference, all-virtual for the second year in a row, began June 7 and continues through June 11. In the meantime, here's everything Apple announced on Day 1 of WWDC 21.
