Installation - Light SDK

macOS
Windows

Light SDK requires macOS 12 or later.

Download the app

Grab the latest LightSDK-macOS.zip from the LightSDK releases page, then unzip it.

Move it to Applications

Drag LightSDK.app into your Applications folder.

Open it the first time

Right-click the app, click Open, then click Open again to bypass the Gatekeeper warning. macOS remembers this, so future launches are a normal double-click.

The right-click step is only needed because the app is ad-hoc signed. A notarized build opens with a normal double-click.

Light SDK requires Windows 10 (version 1803 or later) or Windows 11.

Download the app

Grab the latest LightSDK-Windows.zip from the LightSDK releases page, then unzip it anywhere.

Launch the app

Double-click LightSDK.exe. No installer needed.

Light SDK on Windows uses Microsoft Edge WebView2, which ships pre-installed on Windows 10 (1803+) and Windows 11. If the app fails to start, download and install the WebView2 Evergreen Runtime from that link.
