Glance 1.5.9
Glance 1.5.9
Glance 1.5.9 is a major update focused on interactive folder previews, reliable Open With actions, native macOS 26 design, and safer preview rendering.
Important
Glance 1.5.9 requires an Apple silicon Mac running macOS 26 or later. Intel Macs and earlier macOS versions are no longer supported.
Highlights
Interactive folder previews
Folders can now be explored directly inside Quick Look:
- Expandable recursive folder trees
- Finder-style file and folder icons
- Progressive thumbnails for images, videos, and PDFs
- Search and native outline sorting
- In-place previews for nested files and packages
- Double-click or press Space to preview a selected item
- Open top-level or nested files with any compatible application
Hidden files are skipped. Folder traversal is bounded to 500 items and five levels to keep Quick Look responsive, while thumbnail work is limited and cancelled when the preview closes.
Reliable Open With support
The custom Open With menu now works for both individual files and items selected inside folder previews.
- Opens files once with the selected compatible application
- Does not change the default application association
- Keeps Glance hidden without stealing focus
- Uses a sandbox-safe handoff between the Quick Look extension and Glance
- Validates applications, files, requests, and responses before opening
- Reports failures unobtrusively inside the Quick Look utility bar
Native macOS 26 appearance
Glance now follows the native macOS 26 Liquid Glass hierarchy:
- Removed the redundant inner border from Quick Look previews
- Added adaptive window materials to the main, Supported Files, and Settings windows
- Uses standard macOS controls with native Liquid Glass styling
- Avoids nested glass containers and per-row visual effects
- Supports light and dark appearance, inactive windows, Reduce Transparency, and Increase Contrast
The Supported Files window is also resizable, scrollable, properly aligned, accessible to VoiceOver, and able to wrap long file-type descriptions correctly.
