Use case overview

A writer gave Claude computer use control of his Mac to play chess and create notes; simple tasks worked, complex ones failed, and usage quota nearly ran out.

Reported experience

  1. What they did

    Ben Patterson turned on computer use in Claude's settings on a Mac mini and granted accessibility and screen recording permissions. He also had to approve each app individually. Claude opened Notes and wrote a note, and it added a lasagna shopping list when asked from his iPhone through Dispatch. He then asked it to play Chess.

  2. How it went

    The Notes tasks worked. Claude got stuck trying to move a single chess piece on the 3D board. Those failed attempts used up nearly his whole five-hour Claude Pro allotment in about 30 minutes, so he stopped it.

  3. Worth knowing

    Computer use sends screenshots of your whole screen to Claude and burns usage quickly on a Pro plan, so keep sensitive windows closed and stick to simple tasks.

Example prompts

Try with Claude
Take control of my computer and open [chess app or website]. Play a game against the built-in [easy/medium] computer opponent, then open [notes app] and write a short note summarizing how the game went. Keep to these two simple steps, tell me if something fails instead of retrying endlessly, and stop once the note is saved.
