how to turn off Maps’ location circle
If you’re finding that the large blue location circle is obscuring your view of your current location, here’s a quick script that will allow you to toggle it on and off. You could create a Service and then a hotkey for it, or save the script as an Application and add it to your Dock. That’ll give you a one-click method for toggling the circle on and off – you can also turn it back on (but not off!), just by clicking the usual Location button in Maps’ user interface.
