Leafrune 0.9.4 Beta for Mac

Leafrune for Mac: a fast, private PDF reader with an AI assistant that runs on your own computer. For Macs with Apple silicon (M1 or later).

Install

1. Download Leafrune_0.9.4_aarch64.dmg below and open it.
2. Drag Leafrune onto the Applications folder, then eject the Leafrune disk.
3. Open Leafrune from Applications.
4. The beta is not notarized by Apple yet, so the first time macOS does not open it. Click Done, go to System Settings ▸ Privacy & Security, click Open Anyway next to the Leafrune message, and confirm with your password. You only do this once.

On first launch Leafrune downloads its AI models once (about 3.2 GB) in the background; you can read meanwhile.

To check the download: shasum -a 256 ~/Downloads/Leafrune_0.9.4_aarch64.dmg must match SHA256SUMS.txt.

What's in it

• A Mac app: toolbar in the title bar, translucent sidebar, your accent and highlight colors, the macOS menu bar, Find as a bar under the toolbar, password prompts as a sheet; the window reopens at its last size and place.
• The assistant writes answers with Gemma 4 E2B (Google DeepMind) on the Mac's graphics processor; every answer cites its pages. A Report answer button under each answer opens a filled-in report you can check before sending.

Windows: get Leafrune from the Microsoft Store.
