macOS Tahoe 26 beta 3 is out now for developers! Here’s how to download the latest macOS 26 developer beta on your Mac and what to expect from this update.
macOS 26 Beta 3 Is Now Available For Developers with Compatible Macs, Here’s How to Get It
Apple just released macOS Tahoe 26 Beta 3 for developers, marking another step toward the big macOS 26 release this fall. If you’re testing on a compatible Mac, the update is live and ready to install.
It’s a bug-squashing, performance-boosting kind of beta, not packed with new features (yet), but laying the groundwork for a smoother Mac experience.
How to Install macOS 26 Beta 3 on Your Mac
Already running an earlier beta? You’re just a few clicks away from the latest build:
- Open System Settings
- Go to General > Software Update
- Wait for macOS Tahoe 26 Developer Beta 3 to appear
- Click Update Now and follow the prompts
Not enrolled yet? Sign up for free at developer.apple.com using your Apple ID. Apple’s Developer Program no longer requires a paid membership to access beta software.
What to Know Before Installing macOS 26 Beta 3
While Beta 3 is more stable than earlier builds, this is still a developer beta. That means:
- Bugs? Yep.
- Crashes? Possibly.
- App incompatibility? Almost guaranteed.
This update is meant for testing, development, and feedback, not daily use on your main machine. If you’re a casual user, you’re better off waiting for the public beta, expected later this July 2025.
What’s New in macOS 26 Beta 3?
While Apple hasn’t released full patch notes, testers are reporting improved system responsiveness, smoother animations, and better stability.
Final Thoughts
macOS Tahoe 26 Beta 3 is another solid step in Apple’s journey to the final macOS 26 release. If you’re a developer or power user, go ahead and update your test machine. If not, hang tight for the public beta, it won’t be long now.
