🔎 Overview

MacAgentBench is a comprehensive macOS agent benchmark with:

• 676 tasks across 25 applications
• Deterministic rule-based evaluation with fine-grained multi-checkpoint scoring
• 3 agent frameworks (Baseline, Agent-S3, OpenClaw) and 16+ models evaluated
• Containerized execution — each task runs in an independent Docker container

📊 Key Results

Framework	Best Model	Pass@1
OpenClaw	Claude Opus 4.6	73.7%
Agent-S3	Claude Opus 4.6	66.9%
Baseline	Claude Opus 4.6	39.2%

🚀 Quick Start

1. Set Up the Environment

Download the macOS VM image (~50GB):

pip install huggingface_hub
huggingface-cli download JetLM/OpenClaw-macOS --local-dir .

Install dependencies:

pip install -r requirements.txt

Start the macOS Docker container:

bash launcher/docker/simple_start.sh

Connect via VNC:

vncviewer localhost:5901

2. Run Evaluation

1. Configure your model API in run_example.sh
2. Run:

bash run_example.sh

For specific models with parallel dispatch, see scripts in scripts/run_*.sh.
