## Key points

- Apple issued emergency macOS updates fixing a Screen Sharing authentication flaw.
- Affects Tahoe, Sequoia and Sonoma; updates skipped normal beta testing.
- Mac users should install the patch as soon as possible.

## Summary

Apple has released unscheduled security updates for macOS Tahoe, Sequoia and Sonoma to fix a vulnerability in Screen Sharing, just days after its regular round of 26.6 updates at the end of July. The flaw could allow an attacker on the same network to authenticate to Screen Sharing without valid credentials, and the fact that the updates skipped the usual developer and public beta testing phases suggests Apple treated the issue as fairly serious. Mac users are advised to install the update promptly.

The new versions are macOS Tahoe 26.6.1, macOS Sequoia 15.7.9 and macOS Sonoma 14.8.9, with Apple's on-device update prompt simply describing them as security fixes. The change comes during a busy stretch for Apple's software team, which also began public betas for iOS 27, macOS 27 and related operating systems in mid-July, and two days earlier overhauled its bug bounty programme to cope with a flood of low-quality, AI-generated submissions.
