# macOS Computer Use (universal, any-model) You have a `computer_use` tool that drives the Mac in the **background**. Your actions do NOT move the user's cursor, steal keyboard focus, or switch Spaces. The user can keep typing in their editor while you click around in Safari in another Space. This is the opposite of pyautogui-style automation. Everything here works with any tool-capable model — Claude, GPT, Gemini, or an open model running through a local OpenAI-compatible endpoint. There is no Anthropic-native schema to learn. ## The canonical workflow **Step 1 — Capture first.** Almost every task starts with: ``` computer_use(action="capture", mode="som", app="Safari") ``` Returns a screenshot with numbered overlays on every interactable element AND an AX-tree index like: ``` #1 AXButton 'Back' @ (12, 80, 28, 28) [Safari] #2 AXTextField 'Address and Search' @ (80, 80, 900, 32) [Safari] #7 AXLink 'Sign In' @ (900, 420, 80, 24) [Safari] ... ``` **Step 2 — Click by element index.** This is the single most important habit: ``` computer_use(action="click", element=7) ``` Much more reliable than pixel coordinates for every model. Claude was trained on both; other models are often only reliable with indices. **Step 3 — Verify.** After any state-changing action, re-capture. You can save a round-trip by asking for the post-action capture inline: ``` computer_use(action="click", element=7, capture_after=True) ``` ## Capture modes | `mode` | Returns | Best for | |---|
