Apple has released third release candidates for both macOS Sonoma 14.8.8 and macOS Sequoia 15.7.8, marking an unusual step in the update cycle. These RC versions target developers and beta testers before final public releases. The move suggests Apple is taking extra precautions with these particular updates.

The third RC rollout follows a consistent timeline. Build 23J610 for Sonoma and build 24G812 for Sequoia arrived today, continuing the pattern from earlier RCs on May 26 (builds 23J604 and 24G806) and June 15 (builds 23J607 and 24G809). This represents the third iteration for both operating systems.

Apple's release notes indicate these updates provide important security fixes and recommend installation for all users. However, the company has not yet published detailed security information on its official security releases page. Users can expect the final versions to address vulnerabilities that may affect Mac security and stability.

This rare triple RC deployment signals Apple is prioritizing stability over speed for these maintenance releases, likely addressing bugs discovered during the extended testing period.
