macOS Tahoe 26.5.2
The Current macOS Release — a Security Update Worth Installing Promptly
What's in macOS Tahoe 26.5.2
macOS Tahoe 26.5.2 is the current, latest stable version of macOS as of July 2026. It is a security-focused update with no new user-facing features, and Apple recommends it for all Macs running Tahoe.
- 32 security vulnerabilities patched in total.
- 23 fixes in WebKit and related technologies — the engine behind Safari and any app that renders web content.
- Several kernel vulnerabilities addressed, shared with the matching iOS 26.5.2 and iPadOS 26.5.2 updates.
- Apple has not indicated that any of the patched vulnerabilities were exploited in the wild.
Because most of the fixes are in WebKit — code that processes untrusted web content every time you browse — this is the kind of update you should install sooner rather than later.
Released Alongside
- iOS 26.5.2 and iPadOS 26.5.2 — matching security updates for iPhone and iPad.
- Safari updates carrying the same WebKit fixes to macOS Sequoia and Sonoma.
- Release candidates of macOS Sequoia 15.7.8 and macOS Sonoma 14.8.8 were seeded to testers the same day for Macs still on the older systems.
System Requirements
- MacBook Pro: 2019 and later
- MacBook Air: 2020 and later
- Mac mini: 2020 and later
- iMac: 2021 and later
- Mac Studio: All models
- Mac Pro: 2019 and later
Note: macOS Tahoe 26 is the final macOS release to support Intel Macs. macOS 27 Golden Gate, arriving in September, requires Apple Silicon.
How to Update to macOS Tahoe 26.5.2
- Back up your Mac with Time Machine or a clone before installing.

What's Next
Expect at most small maintenance and security updates for Tahoe over the summer while Apple focuses on macOS 27 Golden Gate, announced at WWDC 2026. Golden Gate is in developer beta (beta 3 arrived July 6), with a public beta this month and a full release expected in September.
