What is the WeatherWidget on Mac?

The WeatherWidget process on Mac refers to the background process that powers the weather information displayed in the macOS Notification Center or Desktop Widgets area. It is part of the system's Notification Center and Today View, which shows various widgets including weather updates, calendar events, reminders, and other info.

You can add the widgets to the Notification Center since macOS Big Sur, and add widgets to the Desktop since macOS Monterey. When you add the Weather widget, the WeatherWidget process is responsible for fetching weather data from Apple's servers or a weather provider. 

This process runs in the background and periodically updates the weather information that you see in the widget. It might also be responsible for fetching data in response to specific user actions, like opening the widget or changing the location settings.

In general, the WeatherWidget process isn't something that users interact with directly. It runs automatically as part of the macOS environment, and you typically won't notice it unless it's using an unusually high amount of system resources.
