Apple has officially released macOS Sequoia 15.7.1 on September 29, 2025, just weeks after version 15.7. This new update is part of Apple’s ongoing support for Macs running Sequoia, even as macOS Tahoe becomes the primary operating system for newer devices.
What’s New in macOS Sequoia 15.7.1
Unlike feature‑rich major releases, 15.7.1 is a maintenance update focused on critical fixes and security patches. Here’s what Apple highlights:
- Security updates – Apple has patched vulnerabilities that could allow malicious apps or web content to execute arbitrary code. While Apple has not yet disclosed all CVE identifiers, the company notes these are important security fixes.
- Stability improvements – Addresses rare system crashes reported by some users after the 15.7 update.
- Compatibility fixes – Improves reliability when running third‑party security and enterprise management tools, an area that had issues in earlier Sequoia builds.
Why This Update Matters
Many Mac users are not upgrading to macOS Tahoe 26 immediately, either due to hardware limitations or enterprise rollout schedules. For those users, Sequoia 15.7.1 ensures continued protection against newly discovered threats.
