Apple pushes emergency macOS patches to close Screen Sharing flaw
Apple issued new updates for macOS Tahoe, Sequoia and Sonoma to fix a vulnerability that could let network attackers access Screen Sharing without credentials.
Apple rolled out fresh versions of its three current macOS platforms—Tahoe 26.6.1, Sequoia 15.7.9 and Sonoma 14.8.9—to address a serious Screen Sharing vulnerability. According to Apple’s support notes, an attacker on the same network could potentially authenticate to the service without valid credentials, and the new builds are intended to seal that gap. The patches were delivered directly to users, bypassing the typical developer and public beta stages, which signals the company’s assessment of the risk.
The update prompt simply states that it provides security updates for the Mac. The timing follows a period of intense software activity, including public betas for iOS 27, macOS 27 and other systems, as well as a recent revamp of Apple’s bug bounty program in response to a surge of AI-related submissions. Users running any of the affected macOS versions should download and install the updates without delay.
Why it matters
Unpatched Macs could be hijacked via Screen Sharing, exposing personal data and network security.
