Nidhi Singh: let Claude Code use Codex's computer use to drive Mac apps (includes a sponsored segment)

Try this

1. Watch Codex computer use work in the background with its own virtual cursor, leaving your mouse free. 01:11
2. Note that it reads an app's buttons and fields (the accessibility tree), not just screenshots. 02:08
3. Treat computer use as the broadest but slowest option: a last resort. 03:10
4. Try options in this order: an MCP server, then bash, then Claude in Chrome, then computer use. 04:09
5. Use it where it earns its keep: testing native or Electron apps, checking layouts, and GUI-only tools like the iOS Simulator. 04:31
6. Register the ChatGPT app's cua_repl program as an MCP server so Claude Code or another MCP agent can use it. 06:30
7. For sites that need you to stay logged in, a browser-session tool works better (this is the sponsored GoLogin pitch). 08:24
8. If the newest mcp.json in the Codex plugin cache has empty args, you've got a stale stub. 10:04
9. Fix it by keeping the ChatGPT desktop app open so it downloads the full plugin. 10:48
10. Remember background mode is Mac-only; on Windows it takes over your screen. 12:02
