According to the same Bloomberg report, iPadOS may get a widgets revamp. The newest version of macOS will be numeral Its name is still a mystery, though Apple is likely to keep consistent with its current naming convention, which means it will be named after some stunning California locale. Still, there are two key elements of any modern macOS update to keep an eye out for. In macOS Catalina, Apple rolled out Mac Catalyst, which was a way for app makers to more easily port their mobile apps over to the Mac desktop.
In recent years Apple has also made some of its mobile apps Mac-compatible—think Podcasts, News, Stocks. This allows you to listen to music, watch TV shows and movies, and share your screen with people over FaceTime. You can tune in and watch the same content together and communicate at the same time over FaceTime. Focus allows users to set different home screens based on times of day. Notifications have also been redesigned with a focus on making them more glanceable.
There is also a new notification summary feature that collects non-time-critical notifications for delivery at a more opportune time, such as in the morning and evening. Apple has announced a handful of new features for Apple Maps.
There are a variety of design updates for Apple Maps to bring a ton more details for cities in commercial districts, buildings, and more.

The first developer beta is available now, while Apple says a public beta will be released in July. A stable release is expected this fall. Next up, Apple introduced iPadOS One of the biggest changes here is that widgets are now available on the iPad home screen for the first time.
No longer are widgets delegated only to the Today View on the side of the home screen, but now they be placed in the midst of all of your other app icons. The App Library is located directly in the dock for easy access to all of your applications, regardless of where you are in iPadOS. The new system is similar to iPadOS 14, but Apple has rethought how you access the controls. The new multitasking menu appears at the top of apps, letting users go into Split View or Slide Over directly from that menu.
You can also now have access to the Home Screen when using Split View, making it easier to get to the right app. The experience is also changed when using an external keyboard with your iPad, with all-new keyboard shortcuts and a redesign of the menu bar.
Users can quickly set up and switch between Split View and Slide Over with new shortcuts for multitasking right from the keyboard. The Translate application is now on the iPad for the first time. Text can now be translated anywhere on iPad by selecting it and tapping Translate, and handwritten text can also be translated. Code is immediately reflected in the live preview while building apps, and users can run their apps full screen to test them out.
One of the biggest changes here is that the Shortcuts automation app is now available on the Mac for the first time. You can build new shortcuts, access existing shortcuts, and more.
