Apple is now distributing the sixth release candidates (RCs) for macOS Sonoma 14.8.8 and macOS Sequoia 15.7.8. This marks an unusually high number of pre-release builds, suggesting Apple is addressing significant issues.

While Apple has not detailed the specific changes beyond "important security fixes" and a recommendation for all users, the timing of these releases is notable. Apple recently expedited the rollout of security fixes for iOS, iPadOS, and macOS, moving patches forward due to risks associated with new AI-powered tools. It is likely that these macOS RCs contain similar critical security updates.

The release build numbers for the latest RCs are 23J619 for macOS Sonoma 14.8.8 and 24G822 for macOS Sequoia 15.7.8. Users can find more information on Apple's security releases via their official channels.
