The feature lets Copilot operate desktop applications: reading accessible app content and visual context, clicking controls, entering and editing text, pressing keys, scrolling, dragging and moving through workflows that span several apps.\n\nGitHub says the aim is to widen what Copilot can automate, including legacy and GUI-only software that offers no API, command-line interface or MCP integration. Its launch demonstration was an expense-report workflow in Safari. The New Stack reports that the feature works in local sessions, reading application content through the operating system's accessibility tree and taking screenshots when it needs visual context.\n\nThe controls are the other half of the announcement. GitHub says Copilot asks for approval before controlling an app, and users can review or reset apps they have marked \"always allow\"; organization-managed settings can disable the feature. Per The New Stack, enterprise policy overrides a developer's local preference, and approvals saved in the CLI carry over to the desktop app on the same computer. To start, CLI users run /computer on, while app users turn on Enable Computer Use in Settings. On macOS, setup walks through the Accessibility and Screen Recording permissions.\n\nWhat stands out is how much GitHub hedges. The New Stack reports the company recommends direct tools, such as an API, MCP server or terminal command, wherever they can do the job, because they give more structured and predictable results than desktop interaction. It also relays GitHub's warnings that Copilot may repeat an action or stall when timing or window state changes, may pick the wrong control, and may take sensitive information visible in a window as context. Enabling the feature in the CLI activates a bundled plugin with its own MCP server, according to the same report.\n\nThe New Stack also frames the launch as catching up with rivals, saying OpenAI added computer use to Codex in April and Anthropic brought broader computer use on macOS to Claude Code and Claude Cowork earlier this year. We have not independently verified those competitor dates.\n\nTwo sources support this account, and they are not fully independent: the GitHub changelog is the company's own announcement, and The New Stack's product details largely trace to GitHub's documentation. We have seen no independent testing of how reliably the feature performs, and neither source addresses plan eligibility or pricing. For anyone considering it, GitHub's own guidance points to using computer use only where no more direct tool exists.\n\nRevised 16 October 2026: Guth re-read the original sources and rewrote this article.
