Fixed a crash on macOS 26 that could cause the app to quit almost immediately after launch, before any UI was drawn (AppKit's new private TouchBar observer conflicted with the app's window lifecycle). Fixed invisible button and label text on macOS 26, caused by a system font (PingFang) rendering with zero width. The app now uses a more broadly compatible CJK font (Hiragino Sans GB) that renders correctly on every supported macOS version, 13 through 26. No visual changes on macOS 13–15; this release only affects text rendering and app stability on macOS 26.

Fixed: The first-run permission setup now auto-dismisses when Screen Recording is already granted, so it stops prompting you to open System Settings on every launch. Fixed: The export "Original" resolution no longer gets stuck at 1280×720. The source resolution is now re-probed each time the export dialog opens, so it matches the actual recording. Bundled FFmpeg 9.0 binaries remain included for reliable screen capture and export. Build 13, signed and uploaded to Mac App Store Connect.

What’s New in 1.3.4 This update introduces an invisible borderline for cleaner captures, fixes original-quality exports so detail is preserved above canvas resolution, and upgrades the bundled FFmpeg engine and Rust dependencies for better performance and stability. We also resolved a sandboxed camera-overlay export issue, added TTF font-index validation to prevent crashes on macOS 26, and tightened App Store entitlements for a more secure, store-ready release.

Add font settings to prevent crashes

Version 1.3.1 Release Notes Fixed Video export failure: Fixed a sandbox issue where the bundled FFmpeg/FFprobe helper tools could not start after App Store download, resulting in "FFmpeg engine not found". The helper tools now correctly inherit the parent app's sandbox. Improvements Reliable bundled FFmpeg: Verified in a local sandboxed test app that both ffmpeg and ffprobe successfully launch and return version output under the same App Sandbox environment used by App Store builds. App icon and packaging: Added the required app icon and ensured all bundled binaries are correctly signed with hardened runtime and sandbox entitlements. Technical Details Version: 1.3.1 Build: 7 Bundle ID: com.knoxcore.knoxstudio Includes ffmpeg and ffprobe 8.1 Signed with Apple Distribution certificate Package signed with 3rd Party Mac Developer Installer certificate Known Issues TestFlight is temporarily unavailable because the main bundle lacks a provisioning profile. This does not affect App Store release. Thanks for your patience — the bundled FFmpeg issue should now be resolved.

Version 1.3 Release Notes Key Fixes Fixed video export functionality: Ensured FFmpeg and FFprobe are properly bundled with the application, resolving the video export failure issue reported by users Improvements Added app icon: Added standard app icon to improve user experience Optimized packaging process: Improved application packaging workflow to ensure all required components are included Technical Details Version: 1.3 Build: 6 Includes complete FFmpeg toolchain (ffmpeg + ffprobe) Signed with Apple Distribution certificate Compatible with macOS 13.0 and later Known Issues TestFlight functionality is temporarily unavailable (missing provisioning profile), but this does not affect App Store release Thank you for your feedback in helping us improve our product!
