How Computer Use agents control your PC: perception, execution, and Mac background mode
dotey · x · 2026-10-24
Dotey publishes a video explainer on how Computer Use agents work: the model only handles 'seeing' and 'thinking,' while a separate program actually clicks and types, looping through observe-plan-act-verify.
It answers four questions: how the agent locates buttons (screenshots, accessibility APIs, software interfaces); why agents can run in the background on macOS but occupy your desktop on Windows; how much faster the new GPT-6 Astra model is and whose numbers back that up; and the safety risks of letting an agent loose on your machine.
