Question: I am flowing the official [tutorial](https://flutter.dev/docs/get-started/install/macos) to install flutter and run the default app on my iPhone Device. After I execute the `flutter run`, the app is installed and launched on my iPhone but the logs show the bellow error. How do I solve it?

```

Answer: 
It happens that there are some process needed to Flutter plugin correctly run on physical devices. I struggled with that and finally found that the processes `idevicesyslog` and `iproxy` were being silently blocked by MacOS.
You may have noticed already a message liked this:

[![Mac suggesting to remove iproxy](https://i.stack.imgur.com/thBaw.png)](https://i.stack.imgur.com/thBaw.png)

or a similar one for idevicesyslog.

Once I went to System Preferences -> Security & Privacy in General tab and allowed this apps, everything works. Note that this screen shows only the last app that you tried to run. So I'd recommend that you run flutter app with preferences opened so you can (hopefully) see the messages appearing and click allow.

[![Option to allow the app. Here it should show one of those 2 names above at a time](https://i.stack.imgur.com/Nl7fs.png)](https://i.stack.imgur.com/Nl7fs.png)

MacOS may warn you one more time about the file being downloaded from the internet. Just click open and you're good.
run the flutter app using flutter run from command line, then the MacBook will ask for permission to open the app and app runs,
