Apple has just released macOS 11.3, alongside iOS 14.5. It’s probably worth updating your Mac to it as soon as you can — not only because it comes with some new features, including improvements for running iPhone and iPad apps on M1 Macs and updates to Apple Music and Podcasts, but it also fixes a major security flaw.
The update reportedly patches a vulnerability that allowed malware to bypass many of macOS’s built-in protections, like File Quarantine and GateKeeper’s opening dialog box. While Apple’s built-in anti-malware system could still block malicious programs if Apple were aware of them, enterprise software company Jamf did find evidence that the security flaw was being exploited by attackers.
Apple also details a slew of other security fixes that are included with the latest update on its security update page. Catalina and Mojave have received security patches as well, for those who haven’t yet updated to Big Sur.
Aside from security updates, one of the biggest new improvements in 11.3 (at least for owners of M1 Macs) is the ability to resize iPhone and iPad app windows. Apple’s also added keyboard, mouse, and trackpad support for games that are compatible with controllers.
Apple has also added autoplay to the Music app — a feature which is either great or annoying depending on your mood. After you reach the end of a song or playlist, Apple Music will continue playing music that it thinks is similar (thankfully, it can be turned off if you’re just looking to listen to one specific song). The News and Podcasts apps also have redesigned pages to make them easier to use (with the former getting a reworked search feature — something that’s exciting to me, and possibly no one else).
