macOS app: Canvas overlay covers permission dialog, creating deadlock
증상
When canvas.present is invoked by the agent, the Canvas overlay renders at a higher z-order (window level) than the “Allow this command?” permission dialog in the macOS app. This creates a deadlock: the user cannot see or interact with the permission dialog to approve or deny the command, and the Canvas overlay won’t dismiss until the command completes.
원인
Race condition or deadlock from multiple concurrent operations targeting the same shared resource without proper locking.
해결법
Send a blind Return keypress via AppleScript to approve the hidden dialog:
osascript -e 'tell application "System Events" to key code 36'
This works because the permission dialog still has keyboard focus even though it’s visually obscured. However, this is fragile — it blindly approves whatever dialog is pending without the user being able to read it, which defeats the purpose of the permission system.
