Mantle for macOS 0.1.0

First release of Mantle for macOS, a native desktop app for Mantle. Python and Node.js are built in, so you don't need to install anything else to run it.

Download and run

1. Download Mantle-0.1.0-macOS-arm64.zip below and double-click it to unzip.
2. Drag Mantle.app into your Applications folder.
3. Open it. The first time, macOS will block it, because this build isn't notarized by Apple yet. To allow it:
   • Open System Settings → Privacy & Security, scroll down to the message about Mantle and click Open Anyway, then confirm.
   • Or run this in Terminal once:

     xattr -dr com.apple.quarantine /Applications/Mantle.app

After that it opens normally.

Requirements

• A Mac with Apple Silicon (M1 or later). Intel Macs are not supported by this build.
• macOS 14 Sonoma or later.
• To run agents you need a model provider login (such as OpenAI or Anthropic). Mantle downloads its Pi runtime the first time you need it. Git is needed only for Git-based resources.

Notes

• Your data is stored in ~/.mantle. If you already use the Mantle CLI, the app picks up your existing agents and logins.
• Built from commit 65aeba7.
• SHA-256 of the zip: 236dce89a8ec1f97c4b811b11bfcbd762f47a80a9572554f020209b720d373d9
