Apple is expected to unveil macOS 27 during WWDC 2026 on June 8, with the first developer beta likely becoming available shortly after the keynote. A public beta is expected to follow in July, while the final stable version should arrive later this year for compatible Macs.
If you’re planning to try macOS 27 as soon as it becomes available, there are several ways to download and install it, depending on whether you want the developer beta, public beta, or the final public release. Here’s everything you need to know.
Download macOS 27 Developer Beta
The developer beta is usually the first version Apple releases after announcing a new macOS update. In recent years, Apple has made developer betas available to anyone with an Apple Account enrolled in its developer program.
Developer betas are designed for testing. They often contain bugs, app compatibility issues, and performance problems. It’s best to install them on a secondary Mac rather than your primary work machine.
- Back up your Mac using Time Machine.
- Sign in with your Apple Account.
- Open System Settings.
- Click General.
- Select Software Update.
- Click the Beta Updates option.
- Choose macOS 27 Developer Beta when it appears.
- Click Done.
- Select Upgrade Now or Install Now.
- Follow the on-screen instructions and restart your Mac when prompted.
The update should then download and install automatically.
Download macOS 27 Public Beta
If you want early access without using the developer version, the public beta is usually the safer option. Apple typically releases public betas after several rounds of developer testing. Reports suggest macOS 27’s public beta could arrive sometime in July 2026.
Public betas are generally more stable than developer betas, but they are still unfinished software. You may encounter bugs and unexpected behavior.
- Visit Apple’s Beta Software Program website.
- Sign in with your Apple Account.
- Enroll your Mac if it is not already enrolled.
- Open System Settings.
- Go to General > Software Update.
- Click Beta Updates.
- Select macOS 27 Public Beta.
- Return to Software Update.
- Click Upgrade Now when the beta appears.
- Complete the installation process.
After restarting, your Mac will boot into the macOS 27 public beta.
Download the Final macOS 27 Release
Most Mac users should wait for the final version. Apple is expected to release macOS 27 to the public in the fall, likely around September, after several months of beta testing.
The final release receives the most testing and typically offers the best performance, battery life, and app compatibility.
Steps to download the stable version
- Open System Settings.
- Click General.
- Select Software Update.
- Wait for macOS 27 to appear.
- Click Upgrade Now.
- Accept Apple’s terms and conditions.
- Allow the download to complete.
- Restart your Mac to finish installation.
How to Check if Your Mac Is Compatible
Apple has not yet published the official compatibility list for macOS 27. That information should become available during WWDC 2026.
To check your Mac model:
- Click the Apple logo in the top-left corner.
- Select About This Mac.
- Note your Mac model and chip.
- Compare it with Apple’s official compatibility list once released.
Apple continues to prioritize Apple silicon Macs, so older Intel-based models may see reduced support going forward.
