Note that new installs of Microsoft 365 for Mac also requires macOS Big Sur 11 or later. Upgrading your operating system to macOS Big Sur 11 or later will allow Office updates to be delivered for your apps.

If you continue with an older version of macOS, your Office apps will still work, but you'll no longer receive any updates including security updates. So what are you waiting for? Go to your Settings > General > Software Update and upgrade to iOS 16.3.1 now to keep your iPhone safe.Starting with the November 2022 update (16.67) macOS Big Sur 11 or later is required to receive updates to Word, Excel, PowerPoint, Outlook, OneNote, and Microsoft Defender. The iOS 16.3.1 update is available for the iPhone 8 and later, iPad Pro (all models), iPad Air 3rd generation and later, iPad 5th generation and later, and iPad mini 5th generation and later. The iOS 16 upgrade also comes with some brilliant new iPhone features, many of which are a boost to your security.

While Apple had previously been updating iOS 15 with important security fixes, it is only doing so for older iPhones that can’t upgrade to iOS 16. If you are on iOS 15 but have an iOS 16-compatible iPhone, now may be the time to update to iOS 16.3.1. However, there’s no reason to believe this has happened in real-life attacks yet, Wright adds. “It’s also theoretically possible to chain the WebKit vulnerability with the Kernel one to gain full access to the device,” he warns. Updating to iOS 16.3.1 as soon as you can is the best way to protect yourself, says independent security researcher Sean Wright.

The stakes are even higher for businesses and high-profile individuals. While the exploited bug probably targets a specific group of people, it’s only a matter of time before more attackers use it more widely. If you are already on iOS 16, you need to update to iOS 16.3.1.
