Apple Releases macOS Security Updates to Address Screen Sharing Vulnerability

Apple released three security updates for macOS yesterday in the form of macOS Tahoe 26.6.1, macOS Sequoia 15.7.9, and macOS Sonoma 14.8.9. The new bits fix the same screen sharing vulnerability on these three versions of macOS.

In the release notes for the updates, Apple explained that “an attacker on the network may be able to authenticate to Screen Sharing without valid credentials.” Even if you don’t use screen sharing, it’s recommended to install the new updates as soon as possible.

On July 27, Apple had already released macOS Tahoe 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8 to fix a much longer list of security flaws. Safari 26.6 was released on that same day on macOS Sonoma and Sequoia to address vulnerabilities in Apple’s WebKit engine.

While it’s normal for Apple to continue supporting older versions of macOS with security fixes, the upcoming macOS 27, which is expected to be released in September, will drop support for Intel-based Macs. macOS 26 Tahoe will be the end of the line for all Mac models with Intel chips introduced in 2019 or later.
