Hey, thanks for the report.

This is a known issue. It’s most often related to Git not being installed. Agent mode needs Git to work. Please try this:

  1. Check if Git is installed: open Terminal and run git --version
  2. If Git isn’t installed, install it from Redirecting…
  3. After installing, fully restart Cursor
  4. Try using Agent again

If Git is already installed but the issue is still there:

  1. CMD+Shift+P → “Developer: Reload Window”
  2. Check Extension Monitor: Settings > Application > Experimental > Extension Monitor Enabled, then CMD+Shift+P → “Developer: Open Extension Monitor” and see if any extensions look problematic
  3. Try running cursor --disable-extensions from Terminal. This will show if the issue is extension-related

You can also send:

  • Logs from Help > Toggle Developer Tools > Console, if there are any red errors
