Apple has released urgent security patches for macOS Sonoma, Sequoia and Tahoe, addressing a critical Screen Sharing vulnerability exploited by attackers with root access, without prior beta testing.
Apple has released security updates for macOS Sonoma, macOS Sequoia and macOS Tahoe, moving all three operating system branches forward at the same time and doing so without first seeding developer or public betas. The new builds are Sonoma 14.8.9, Sequoia 15.7.9 and Tahoe 26.6.1, and Apple says the updates are recommended for all users.
For much of the day, the company had not yet published a detailed security bulletin, but the timing suggested the patches were meant to close an issue Apple did not want to leave until a later release cycle. Apple has now said the updates address a Screen Sharing vulnerability, adding a clearer explanation to what had initially been described only as important security fixes.
That context matters because recent reporting has shown Apple has been dealing with a serious macOS flaw affecting systems with Screen Sharing or Remote Management enabled, particularly where the older VNC password option is used. Security researchers at Bynario said the bug could allow an attacker with the VNC password to gain root-level access, and TechRadar reported that Apple later tracked the issue as CVE-2026-43760. Against that backdrop, Mac users on Sonoma, Sequoia or Tahoe have strong reason to install the latest updates as soon as possible.
