Apple has officially released the macOS 26.5 developer beta 1, giving developers early access to the next macOS update.
This beta arrives alongside iOS 26.5 and iPadOS 26.5 betas and is expected to be the last major macOS 26 update ahead of WWDC26, where Apple will preview macOS 27.
How to download macOS 26.5 developer beta 1
Developers can download and install the new beta on compatible Macs using these steps:
- Backup your Mac to ensure your data is safe
- Open System Settings
- Go to General > Software Update
- Click the ‘i’ icon next to Beta Updates
- Select macOS Developer Tahoe Beta from the top-right dropdown
- Tap Done and wait for the beta to appear for download
Once installed, macOS 26.5 beta 1 (build 25F5042g) will be ready for testing.
What to expect in macOS 26.5 beta 1
While Apple has not confirmed all changes, early expectations include:
- Performance improvements and minor refinements
- Continued stability updates ahead of macOS 27
- Bug fixes for issues discovered in macOS 26.4, which introduced Charge Limit, eight new emoji, Rosetta 2 sunsetting alerts, and Safari compact tab view
As with any developer beta, features may change before the public release, so caution is recommended.
