Apple Seeds Second RCs for macOS 14.8.8 and 15.7.8 With Security Fixes

3 articles · Updated · 9to5Mac · Jun 15

Summary

  • Apple issued second release candidates for macOS Sonoma 14.8.8 and macOS Sequoia 15.7.8, signaling the two older Mac operating systems are nearing public release.
  • The new builds—23J607 for Sonoma and 24G809 for Sequoia—carry only “important security fixes” in Apple’s notes and are recommended for all users.
  • These are the second RCs after initial candidates on May 26 and public betas on May 28, an unusual step because Apple’s other updates released the same day were standard 26.6 beta builds.
  • That split suggests Apple may ship Sonoma 14.8.8 and Sequoia 15.7.8 within days, extending support for users who cannot or do not want to move to the latest macOS.
