CEO Tim Cook delivers the keynote address Monday during the 2020 Apple Worldwide Developers Conference in Cupertino, Calif., and provided a glimpse at upcoming software changes as they minimize personal contact during the worst pandemic in a century.

Apple on Monday provided a glimpse at upcoming software changes designed to make the iPhone even easier to use and also announced a long-anticipated shift to a new type of chip to power its line of Mac computers.

The preview of the next version of the iPhone’s operating system, known as iOS 14, highlighted Apple’s annual conference for computer programmers and mobile app makers. The event, which was delayed for three weeks due to the coronavirus pandemic, took place in virtual form via a webcast from the company’s Cupertino, Calif., headquarters.

In recognition of the pandemic, Apple’s next iPhone operating system will include an option to put a face mask on a personalized emoji. Upgraded software for the Apple Watch will also detect when wearers wash their hands.

Apple CEO Tim Cook kicked off Monday’s session with remarks that acknowledged the nationwide protests triggered by George Floyd’s death last month at the hands of Minneapolis police, as well as the social and business challenges posed by the pandemic.

But most of the presentation revolved around an array of new features that, for instance, could help iPhone users manage their apps better, find new ones, and use their phones to unlock and start their cars remotely. (Though that last feature will initially only be available for a 2021 BMW model.)

Apple also promised an upgraded version of its digital assistant Siri intended to make it smarter and less cumbersome, helping it fend off rival voice-activated concierges made by Google and Amazon.

Apple also said its Mac computers will begin using its own chips as it phases out the Intel processors that have powered the machines for the past 15 years. Some Macs will have the Apple chips before the end of the year, but the full transition away from Intel chips won’t be completed until 2022. There had been speculation that Apple would unveil apps that rely on augmented reality, or AR, a technology that melds digitally projected images with the real world. Although Cook has been hyping AR has the next big wave in technology, it hasn’t caught on in the mainstream yet and Apple didn’t drop any new bombshells about it during Monday’s event.
