WWDC 2021: Apple's biggest announcements, from iOS 15 to new ways to use FaceTime

At its annual WWDC conference Monday, Apple unveiled upgrades to many of its operating systems, most notably iOS 15. Apple also unveiled MacOS Monterey, previously known as MacOS 12, along with WatchOS 8 and iPadOS 15. (The rumored HomeOS, however, did not make an appearance.) Developer betas of all Apple OS upgrades are available today, but the general public will have to wait a while for public betas, with wide releases likely coming sometime this fall.

In Apple's big keynote address, at Tim Cook's helm, the iPhone giant also unveiled some new tricks for existing products like 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 one of WWDC 21.
