Environment

• ChatGPT Desktop for macOS
• Version: 26.707.91948
• macOS Tahoe 26.3.1
• Computer Use plugin version: 1.0.1000387

Issue

Computer Use cannot start in any task.

The Computer Use plugin is installed correctly.

• MCP server is ON
• Computer Use skill is ON
• Launching through the official "Try now" button creates a task that immediately reports:

"Computer Use interaction runtime isn't available in this task's toolset."

Other messages observed:

• "UI-control tool wasn't exposed."
• "Computer Use interaction runtime isn't available in this task."
• "Required node_repl Computer Use interface isn't available."

Expected behavior

Clicking "Try now" should start a Computer Use session, request macOS permissions if necessary, and allow ChatGPT to control local applications.

Actual behavior

The runtime never starts and macOS never requests Accessibility or Screen Recording permissions.

The issue occurs even when launching Computer Use through the official "Try now" button on the Computer Use plugin page. The task is created successfully, but the Computer Use runtime is never attached to the task.

Troubleshooting performed

• Reinstalled the Computer Use plugin
• Restarted ChatGPT
• Restarted macOS
• Created multiple brand-new tasks
• Used the official "Try now" button
• Tested with TextEdit, Chrome, and Chess.app
• Verified MCP server is enabled
• Verified Computer Use skill is enabled

No change after any of the above steps.
