Anthropic shipped background computer use on macOS, with an escalation ladder before screen takeover.

Announced by Anthropic's official account, Claude can now drive your computer in the background in both Claude Cowork and Claude Code, clicking, typing and opening apps while you work in another window, as long as the machine is on and the desktop app is open. Beta for Pro and Max, macOS only, under Settings → General → Computer use, already enabled for anyone who used computer use before. The design detail I'd copy: Claude tries connectors first, then the in-app browser or Chrome, and only seizes cursor and keyboard as a last resort, asking permission once per session and waiting for you to stop typing.
