Spatial Slideshow 0.7.0

First public experimental release of Spatial Slideshow for Apple Silicon and macOS 27.

Spatial Slideshow uses the actual installed Apple Photos Reframe models and Gaussian renderer to animate photos with depth. Choose a Photos album or local images, then play with varied camera motion, persistent caching, fades, music, optional videos, and fullscreen controls.

Settings and framing

• A dedicated Settings window replaces the large options menu.
• Optional Apple Fast Clean Up edge expansion adds camera travel room while keeping the original composition close in view.
• Maximum zoom out controls how much generated area may be revealed. It defaults to 0%; the limit follows the amount of expansion.
• New-user defaults: 9 seconds, Strong varied motion, Fit with Black Bars, fades and shuffle on, full-quality unedited originals at 3840 pixels. Expansion and videos start off.
• Existing saved preferences are retained.

Download and requirements

Download the arm64 ZIP below, extract it, and open Spatial Slideshow.app. It requires macOS 27, Apple Silicon, and the supported Photos models already installed locally. Optional expansion also requires Photos Clean Up assets. Apple frameworks and model weights are not bundled.

This is an ad-hoc signed, non-notarized prerelease using private APIs. It has been verified on the development Mac; compatibility across other macOS builds and machines is not established. A downloaded app may require macOS's normal user approval to open.

Validation

• 12 synthetic test suites passed, covering cache persistence, preparation, playback, navigation, controls, camera math, music, and display sleep.
• Actual Apple Clean Up → Reframe → video pipeline passed on a Trip photo, including cache reuse in a separate process.
• Trip-based visual comparison checked the zoom-out range and return toward original framing.
• Fresh-profile settings and preservation of existing preferences checked in the running app.

Source includes build/test tools, the app icon, and reusable research probes. Personal media, generated caches, Apple binaries, model weights, and decompiled implementation files are excluded.
