Apple is encouraging billions of users of Mac and MacBook devices worldwide to update them to the latest version of macOS, following the macOS 15.1.1 Sequoia, launched earlier this week. This update comes within nearly a month of the major release of macOS 15.1, which not only bashed out minor bugs but also forwarded several security patches along with the launch of Apple's generative AI tools in the Apple Intelligence suite.
What Does the Update Address?
The macOS Sequoia 15.1.1 update addresses two critical security issues. The first concerns a vulnerability in JavaScriptCore, which Apple describes as including "maliciously crafted web content" that could potentially cause harm. The second one is related to WebKit and allows "maliciously crafted web content" to gain access to "cross-site scripting.". These issues are tracked under CVE-2024-44308 and CVE-2024-44309. For the more technical reader, cybersecurity consultant Kate O'Flahery has written in greater depth on the character and potential consequences of these flaws.
Meanwhile, CISA of the United States has underscored the urgency of this update. This agency warns, "A cyber threat actor could exploit these vulnerabilities to take control of an affected system." "Users and administrators are advised to review security advisories and apply relevant updates to protect their devices," it recommended.
macOS 15.1.1 Update Available Across Multiple Apple Devices
Apple rolls out iOS 18.1.1 and iPadOS 18.1.1, fixing similar security concerns as in the macOS update. According to Forbes contributor David Phelan, "the iPhone and iPad update includes not just fixes for iOS 18 but devices running iOS 17, so the patches become available on a huge range of Apple devices.".
mac OS Sequoia supports M-series chips-powered Mac and MacBook. This means that several Intel-based Macs are also in support, but more importantly, with Xeon W or Coffee Lake process and above. This is to say, iMac Pro 2017 or later, iMac 2019 or after, MacBook Pro 2018, Mac Mini 2018, and Mac Pro 2019 or later models can be updated immediately.
How to Update Your Mac or MacBook Pro
To manually update your macOS, follow these steps:
Go to System Settings > General > Software Update, and click Update Now.
(On older Macs, go to System Preferences > Software Update to find the update option.)
Apple encourages all users to install the update as soon as possible to ensure their devices are protected from potential cyber threats.
