Public beta testers can download ‌‌macOS Big Sur‌‌ 11.3 from the Software Update section of the System Preferences app after installing the proper profile from Apple’s beta software website. Those who want to test the update can sign up on Apple’s site.

‌macOS Big Sur‌ 11.3 brings new customization options for Safari, adding a way to rearrange the different sections on the Start Page like Favorites, Reading List, Siri Suggestions, Privacy Report, and more. Developers also have access to a new integration to develop features for the Start Page.

The update includes optimizations for using iOS apps on M1 Macs. When running iPhone and iPad apps on ‌M1‌ Macs, there’s a Touch Alternatives preference pane to set keyboard commands for touch input alternatives, plus iPadOS apps launch with a larger window if the Mac’s display allows for it. Touch Alternatives can be enabled for ‌iPhone‌ or ‌iPad‌ apps by clicking on the app’s name in the menu bar and then selecting the Preferences option. Touch Alternatives let you customize taps, swipes, and drags with keyboard commands.

‌macOS Big Sur‌ 11.3 adds support for the latest PlayStation 5 DualSense and Xbox Series X/S controllers for use with macOS games.

In the Reminders app, reminder lists can be sorted by Due Date, Creation Date, Priority, or Title, and there is an option to print lists by going to File > Print. Reminders can also be moved manually across lists with drag and drop, something that wasn’t possible before.

Apple added a new “Made For You” library shortcut in Apple Music for finding personal mixes and Replay playlists, and the Listen Now section has been updated with support for highlighting live events.

There’s also a new autoplay feature in the ‌Apple Music‌ app that lets the streaming service to continue to play music after a playlist or music queue ends. ‌Apple Music‌ sources music similar to what’s in a person’s ‌Apple Music‌ library, with the feature mimicking the autoplay option added to ‌Apple Music‌ in iOS 14.

‌macOS Big Sur‌ 11.3 adds support for HomePod Stereo pairs, allowing a set of paired HomePods to be set as the default sound output option, with the two HomePods showing up as a single selectable speaker rather than separate as in prior versions of macOS.

Code in the update suggests that the Optimized Battery Charging feature will now make sure the Mac’s battery is fully charged before a scheduled calendar event. The Mac will charge to 100 percent three hours before a calendar event’s start time.

Optimized Battery Charging is designed to preserve the lifespan of the Mac’s battery by limiting the amount of time that a Mac sits at 100 percent battery.

In Safari, there’s support for WebM video playback, allowing users to play WebM videos using Apple’s browser. WebM is a niche video format designed to be a royalty-free alternative to the H.264 codec used in the MP4 format. WebM allows video files to remain small without sacrificing quality and can be played with little processing power, making it ideal for webpages and browsers.

Code in found in the third ‌macOS Big Sur‌ 11.3 beta suggests that Rosetta could be removed from some ‌M1‌ Macs in some select regions after the software is released. There’s a mention that “Rosetta is no longer available in this region. Applications requiring Rosetta will no longer run,” but no additional information is available at this time.

There are also appear to be new assets that suggest a feature for mapping game controller buttons to keyboard layouts, and there’s a Game Center toggle to enable or disable connections with friends, which lets games set you up with your friends or prevents apps from accessing that info.

More on ‌macOS Big Sur‌ can be found in our macOS Big Sur roundup. The software is expected to see a release this spring.
