Anthropic launched Claude Computer Use and Dispatch on March 23, 2026, giving Claude the ability to autonomously control macOS desktops — opening apps, navigating browsers, filling spreadsheets, and completing multi-step tasks. Dispatch pairs a mobile device with a Mac via QR code, allowing users to text Claude instructions from their phone and receive results when the tasks complete.
How It Works
Claude Computer Use operates through a priority hierarchy. When direct integrations exist — Slack connectors, Google Calendar APIs, file system access — Claude uses those first for speed and reliability. When no integration exists, Claude falls back to screen control: reading pixels, moving the mouse, clicking buttons, and typing text. The setup requires enabling Computer Use in Claude Desktop settings and granting macOS Accessibility and Screen Recording permissions.
Dispatch extends this by decoupling the instruction from the execution location. Users scan a QR code to pair their iPhone with their Mac, then send tasks via the Claude mobile app. Claude executes on the desktop — which must remain awake — and returns results to the phone. The use case is straightforward: assign research, data entry, or multi-app workflows before leaving your desk and find them completed when you return.
Performance and Limitations
The March 2026 update reduced error rates approximately 40% on desktop application interactions compared to the initial Computer Use release. Sonnet 4.6 hit 72.5% on OSWorld-Verified — matching human expert performance at 72.4% and scoring 94% on the Pace Insurance Benchmark for computer use tasks.
Limitations remain. Complex tasks sometimes require second attempts. Screen-based interaction is inherently slower than direct API integrations. macOS is the only supported platform — no Windows or Linux support. And the Mac must stay awake with the screen unlocked for Dispatch to work, which creates a physical security consideration that Anthropic’s documentation acknowledges but does not fully resolve.
Claude Computer Use is available for Pro ($20/month) and Max plan subscribers in research preview. For the cost of a subscription, it replaces much of what the “$600 AI Mac Mini” trend promised — a dedicated machine running AI tasks autonomously — at a fraction of the hardware investment.
