1. Create an app that runs on all platforms: flutter create some_app
2. Run flutter attach from the some_app/ directory
3. In another terminal, run flutter run -d macos from the some_app/ directory
4. Observe, the flutter attach command times out waiting for the VM service connection

If you happen to have a simulator open, and then repeat steps 2 & 3, flutter attach assumes it is waiting for a connection on the iOS simulator even though the app I'm trying to connect to was ran on the macos target.
