The all-new macOS Big Sur 11.3 update is now available for compatible Macs. It adds support for AirTag, includes app improvements for Macs with M1, introduces new emoji, and adds more diverse voice options for Siri.

Apple late on Monday rolled out its latest macOS Big Sur 11.3 update, which is the third update to the Big Sur operating system. It is now available for download on all compatible Macs. Users can manually check for update via Settings app > Software Update. One of the major highlights of the new Big Sur update is that it brings optimisations for M1 Macs launched in October last year. The latest update also adds support for the company's all-new tracking accessory, AirTag. The all-new Big Sur 11.3 update also brings the option to change an iPhone or iPad app's window size and support for displaying the highest resolution version of an iPhone or iPad app on full screen. Much like iPhones, the new update on Mac also brings diverse voice options for Siri. There's also Safari enhancements like a customisation option for the Start page section, WebM and Vorbis video and audio format support. The macOS Big Sur 11.3 update adds support for Xbox Series X S Wireless Controller and Sony PS5 DualSense Wireless Controller on the gaming front. For Mac computers with an M1 chip, the new update adds hibernation support. The latest update is over 5.5GB in size, and we recommend users download it via Wi-Fi to save mobile data. With the latest update, Apple also fixes old malware. The company told Techcrunch that macOS 11.3 fixes the macOS bug that exploited vulnerabilities.
