If you opened Software Update on your Mac today, you may have noticed a small new release waiting: macOS 26.4.1. It’s not a feature-packed update, but it quietly fixes an issue that could prevent some newer MacBooks from connecting to certain secure Wi-Fi networks.
The update arrives just a day after Apple pushed iOS 26.4.1 and iPadOS 26.4.1 for the iPhone and iPad. When Apple releases updates across several platforms within a short window like this, it usually means the company is addressing bugs discovered after a larger rollout.
Here’s How to Fix the Wi-Fi Issue
If your MacBook has had trouble connecting to secure or managed Wi-Fi networks, installing macOS 26.4.1 should resolve the problem.
To update your Mac, open System Settings, select General, then click Software Update. If macOS 26.4.1 appears, choose Update Now and follow the prompts. Your Mac will restart once the installation finishes.
After updating, affected Macs should be able to connect normally to 802.1X Wi-Fi networks, including those commonly used by workplaces, universities, and other managed environments.
What the Update Actually Fixes
One confirmed fix affects Macs powered by Apple’s M5 chip family. According to Apple’s enterprise documentation, some MacBook Air models with the M5 chip and MacBook Pro models using M5 Pro or M5 Max struggled to connect to certain secure networks.
The issue appeared when those networks used 802.1X authentication together with content filter extensions. These tools are commonly deployed by businesses and schools to manage network access, filter traffic, and enforce security policies.
Apple later clarified the fix in its updated support documentation: “Resolved an issue where MacBook Air with M5 and MacBook Pro with M5 Pro or M5 Max failed to join 802.1X Wi-Fi networks while using content filter extensions.”
For users who rely on managed networks—such as those in offices, universities, or enterprise environments—this fix could restore connectivity that previously failed or behaved inconsistently.
A Small Update, But an Important One
Compared with the larger macOS 26.4 update released in March—which introduced new emoji, updates to Apple Music and Podcasts, and several security patches—this release is much smaller.
Apple has also not published any new CVE security entries tied to macOS 26.4.1 so far, suggesting the update focuses primarily on stability and bug fixes rather than major security changes.
That pattern is fairly typical. Smaller “.1” updates often arrive shortly after a major software release to address issues discovered once the update reaches millions of devices in real-world use.
There may also be another improvement included. Earlier this week, iOS 26.4.1 fixed an iCloud syncing issue that sometimes prevented data from updating across apps. Because macOS shares many underlying components with iOS, it’s possible the same fix has been applied on the Mac side as well, though Apple has not explicitly confirmed that.
For most users, installing macOS 26.4.1 will simply be a routine update. But for anyone affected by the Wi-Fi bug—especially those connecting to corporate or campus networks—it could make the difference between a frustrating connection failure and a normal working day.
