Apple has sent an urgent update for macOS to billions of Mac and MacBook customers worldwide.
Earlier last week, macOS 15.1.1, the most recent version of Sequoia, was made available. Less than a month has passed since the significant 15.1 release, which included the first wave of generative artificial intelligence software in the Apple Intelligence suite along with several minor Apple issues and security warnings.
After all, Macs as old as the 2020 MacBook Air can run Apple Intelligence indicates that Apple isn’t overly concerned with updating its Mac hardware. If Mac customers can utilize Apple Intelligence on their four-year-old machines, there is no urgent need to prepare them for it, suggesting that Apple is not under any pressure to upgrade its Mac hardware. It’s fantastic for a Mac user that my M1 Mac mini will support Apple Intelligence.
Two Apple issues have been fixed, according to the macOS Sequoia 15.1.1 release notes. First, a JavaScriptCore bug (related to “maliciously crafted web content”) is fixed, and then a WebKit bug (related to “Processing purposefully designed web content can give rise to a cross-site scripting attack”) is fixed. CVE-2024-44308 and CVE-2024-44309 are the documented numbers for this. Kate O’Flahery, a Forbes writer, has examined the technical aspects of these attacks.
The U.S. Cybersecurity and Infrastructure Agency’s intervention has emphasized how important it is to implement this update. Apple has published security upgrades to fix vulnerabilities in several of its devices. Some of these flaws might be used by a cyber threat agent to take over a compromised machine. Users and administrators are urged by CISA to read over the following warnings and implement any required upgrades.
The macOS version came out at the same time as the iOS (18.1.1) and iPadOS (18.1.1) updates. David Phelan, a writer for Forbes, has examined the iPhone upgrade in further detail. In addition to the iOS 18 update for the current model, Apple is also releasing an iOS 17 update to make sure the changes work with the greatest number of iPhones.
All MacBooks and Macs running Apple Silicon are compatible with macOS Sequoia. macOS Sequoia supports several Intel-powered Macs, including those with the Xeon W and Coffee Lake or later chipsets, in addition to any Mac with these M-series chipsets. Thus, the iMac Pros that have been available since 2017, the iMacs released since 2019, the Mac Minis since 2018, and the MacBook Pros since 2018 & 2019 are all supported and ought to be updated as soon as feasible.
To start a manual update to macOS 15.1.1, go to the System Settings / General / Software Update and click Update Now. Go to System Preferences and select Software Update to access this in a different area on old Mac hardware.
Hence, the necessity of upgrading macOS 15.1.1 is highlighted by Apple issues and warnings. Protect your MacBook or Mac, address security flaws, and get new features right now.
