Apple will end security support for macOS Sonoma in late 2025. Federal agencies still running Sonoma should plan their upgrade path now.
Timeline
Based on Apple’s typical support cycle, macOS Sonoma 14.x will likely receive its final security update in October 2025. After that date, new vulnerabilities won’t be patched.
What This Means
Running unsupported macOS versions violates most federal security policies. CISA’s BOD 22-01 requires agencies to remediate known vulnerabilities, which becomes impossible without security updates.
Next Steps
Start testing macOS Sequoia compatibility with your agency’s applications now. Work with your IT team to establish an upgrade schedule that ensures all systems are current before Sonoma’s end-of-life date.
Check Apple’s official support documentation for the exact timeline when announced.
