Apple has officially released macOS Tahoe 26.5.2 to the public, bringing important security fixes to the Mac.
The software carries build number 25F84. Apple's official release notes for the update are brief, stating simply that the firmware provides security fixes for your Mac.
The update arrives alongside today's release of iOS 26.5.2 and iPadOS 26.5.2, addressing vulnerabilities across Apple's ecosystem. It also follows the highly targeted macOS Tahoe 26.5.1 patch from earlier this month, which resolved a specific issue causing M5-powered Macs to unexpectedly shut down on restricted enterprise networks.
Mac owners are encouraged to install the latest software to keep their machines secure. You can download the update over the air by opening System Settings, navigating to General, and selecting Software Update. For those who prefer a manual installation or need a full restore image, direct download links are available on our Where to Download macOS Tahoe page.
