Shortly after the announcement of macOS Catalina and iOS 13, Apple released beta versions to developers. Leaks from these testers have given us more information about the new operating systems.
Catalina brings a lot of new features, but also says goodbye to an old one: the Dashboard. Screen Time comes to the Mac, along with some new parental controls. Clicking the green button at the top of windows will give you the choice of using the app full screen, split screen, or moving the app to the iPad screen if you are using the new Sidecar feature alone with an iOS 13 iPad. The new Music, Podcasts and TV apps seamlessly replace iTunes, with all purchases and content access going to the proper app. The Finder will take over iOS device syncing with screens that look very similar to what we have now in iTunes.
iOS 13 brings Wi-Fi network selection to the Control Center, and will let apps like Spotify work through Siri commands. The volume control indicator will move to the edge of the display. iOS 13 will include an interesting new optimized battery charging feature that keeps your battery at about 80 percent charge during the night and completes a 100 percent charge just before you wake up to prevent some battery aging.
Both Catalina and iOS 13 are only available to developers now, but will be released as public betas in July, then to everyone most likely in September.
