What macOS Sonoma 14.8.7 Fixes

macOS Sonoma 14.8.7, released May 11, 2026, fixes 44 vulnerabilities in 28 parts of the system, according to Apple's security advisory.

Apple does not say that any of them were exploited before the fix. That makes macOS Sonoma 14.8.7 a routine security update: worth installing soon, not an emergency.

It has since been superseded: the newest security release for macOS Sonoma is macOS Sonoma 14.8.9, from August 6, 2026, which includes these fixes.
