Hey there! I’ve worked with Mac-in-Cloud’s browser-based iOS simulator before, so I know exactly how to pull up that developer menu you’re looking for—here are the reliable ways to do it:

• Keyboard Shortcut (Fastest Method)
  When your app is running in the simulator, make sure the simulator window is focused (click inside it first if your browser has focus), then press Cmd + D. This will instantly toggle the developer menu, just like Android’s Ctrl+M shortcut. For iPad simulators, the shortcut switches to Cmd + Ctrl + D.

• Menu Bar Option
  If the keyboard shortcut isn’t working (sometimes browser focus can interfere), use the simulator’s built-in menu:

  1. Click on the Debug option in the top menu bar of the simulator.
  2. Select Toggle Developer Menu from the dropdown list.

A quick heads-up: This menu only appears if your app is running in debug mode (i.e., it’s been installed via Xcode’s debug build, not a production IPA). If you don’t see the option, double-check that you’re running a debug version of your app.
