TestFlight update brings managed background assets and faster macOS app installs on Apple Silicon

Apple’s TestFlight app for distributing pre-release software has been updated with new features and performance gains.

Apple released TestFlight version 3.9 today, introducing managed background asset testing and a speed boost for beta app installation on recent Macs.

• Introduction of managed background assets (self-hosted assets) and Apple-hosted background assets for testing
• Faster installation of macOS apps on Apple Silicon
• Stability improvements and bug fixes

Apple announced Background Assets as part of WWDC 2025. It describes the technology as “a new feature that enhances the app launch experience by allowing you to download and update app assets separately from the main app.” The feature is supported on iOS, iPadOS, macOS, tvOS, and visionOS.

The latest version of TestFlight is available now in the App Store.
