SmartHopper 1.4.3: macOS Compatibility, Provider Security, and Smarter AI Canvas Tools

This patch promotes the 1.4.3 release candidate to a stable release with no additional changes. From the last stable release (1.2.4), this release provides full macOS support through Yak/Rhino Package Manager, a safer cross-platform provider verification system, an updated AI model catalog, and more reliable AI-generated script placement on the Grasshopper canvas.

Detailed list of changes

🖥️ macOS Compatibility

• Full Yak/Rhino Package Manager support for macOS, including fixes for race conditions, GhJSON validation, JSON parsing, and URL handling.
• First release open to everyone (not just as a pre-release) as macOS-compatible through Yak/Rhino Package Manager.
• Platform-appropriate provider security: Authenticode + hash verification on Windows, hash-only on macOS.
• Fixes "Compatibility with Mac" (#263) and macOS-specific issues in 1.4.0-alpha (#389, #393, #395).

🔒 Provider Security

• SHA-256 hash verification for AI provider DLLs.
• Three-tier verification modes: Soft, Hard, and Strict.
• Manual verification menu item and a comprehensive status dialog.
• Improved offline detection, caching, and reduced timeout for faster hash checks.

🛠️ Grasshopper Components & Canvas Tools

• Component name alias resolution: AI tools can use informal names like "python" or "slider" and resolve them to canonical Grasshopper components via the live component server before GhJSON placement.
• script_generate output is now correctly placed by the GhPlace component.
• gh_put can instantiate components when the AI uses informal component names.
• Script code is now properly applied to placed script components after alias resolution.
• AIScriptGenerator renamed to AIScriptGenerate for consistent naming.
• Fixed Id missing GhJSON validation errors in script tools.

🤖 AI Models

• Refreshed model registries across Anthropic, DeepSeek, Gemini, MistralAI, OpenAI, and OpenRouter.
• Adjusted default models and rankings across providers based on official documentation.

⚙️ Settings & UI

• Enhanced About Dialog now shows the current SmartHopper version and platform information.
• Fixed encryption initialization to use local hash storage.
• Improved provider status dialog messaging, sizing, and text wrapping.

🏗️ Infrastructure & Stability

• Improved provider stability, thread safety, and timeout handling.
• Centralized canvas connection and replacement logic to preserve external wires during component replacement.
• Improved AI capability bit ordering and model catalog consistency.

🛠️ Technical Requirements

• Rhino 8.24 or above is required
• Windows 10/11 or macOS
• Valid API keys for at least one supported AI provider

⚠️ Important Notes

• API keys are required, and usage costs apply based on your provider and model choices
• Selecting the right provider and model for each task is key to getting the best results and requires some trial and error.

🚀 Getting Started

1. Install SmartHopper in Grasshopper
2. Add your API key in SmartHopper Settings
3. Click the SmartHopper button on the canvas to start chatting
4. Drag AI components onto your canvas for specific tasks
5. Explore a new endless world of possibilities with SmartHopper!
