Apple Fixed the M5 Wi-Fi Bug Everything New in macOS Tahoe 26.4.1.

Apple Releases macOS Tahoe 26.4.1: Critical Wi-Fi Fixes for M5 MacBook Models

Following the recent release of iOS 26.4.1, Apple has rolled out macOS Tahoe 26.4.1. While the general release notes briefly mention "bug fixes and performance improvements," further details from Apple’s Security and Enterprise support pages reveal critical patches for the latest hardware and security vulnerabilities.

The Enterprise Fix: Wi-Fi Connectivity on M5 Chips

The most notable change in this update addresses a specific connectivity issue for power users. Apple informed enterprise customers that macOS 26.4.1 resolves a bug affecting the MacBook Air M5 and MacBook Pro (M5 Pro / M5 Max).

Prior to this patch, these latest-generation Macs experienced failures when attempting to connect to 802.1X Wi-Fi networks—commonly used in corporate and academic environments—if a content filter was active. This fix is essential for professionals working in managed network environments.

Security and Stability

In addition to hardware-specific fixes, the Apple Security documentation confirms that this update addresses several under-the-hood security vulnerabilities. While Apple has not disclosed the full nature of these flaws to prevent exploitation, the update is highly recommended for all users to ensure system integrity.

How to Update

For users without automatic updates enabled, the patch can be installed manually by navigating to: System Settings > General > Software Update

The 802.1X Wi-Fi bug specific to the M5 family reflects the complexity of the new Secure Enclave's built-in security system. The fact that the Content Filter interferes with enterprise-level authentication protocols indicates Apple is retuning the network stack architecture to support higher data transfer speeds at the M5 chip level.

Although Apple refers to it as 802.1X, experts speculate that this update also subtly improves the stability of Wi-Fi 7, the new standard in the MacBook Pro M5, to reduce latency issues when used with the increasingly widespread new routers.

macOS 26.4.1 arrives during the "mid-cycle" of the year. Typically, updates ending in .4 or .5 are the most stable versions and are the ones that large organizations begin to "approve" for employee upgrades across the company. This 802.1X bug fix therefore "greenlights" corporate users to fully migrate to macOS Tahoe.

The fact that Apple released this update just one day after iOS suggests the presence of a vulnerability of this type. Cross-platform vulnerabilities affecting both iPhones and Macs (such as bugs in WebKit or ImageIO) mean that updating quickly isn't just about features, but also about protecting against malicious actors who might try to exploit these vulnerabilities through browsers.
