Fully customizable

Use the Setup application to pick the sections and system components you want to include in the widget. You can also choose your preferred units here.

For your convenience, the setup application can be launched from the widget at any time.

Advanced features

Most Macs have several temperature sensors for each system component. In VitalSigns, the one with the highest temperature is selected by default, but you can change it at any time.

Just click the little gear icon when hovering your mouse over a system component and choose a sensor from the list.

Visual style

Fan speeds are displayed through animated gauges, for a quick and easy interpretation. If you want more accuracy, numerical values are also shown for each fan.

You may choose between absolute RPM readings and percentage of maximum fan speed.

Smart design

A combined indicator shows the Physical, Used and Available memory in your system at any given time. This section also shows how your RAM is currently being used.

Both the Setup application and the Widget use the same graphics style for a meaningful, consistent look.

Notification Center widget

Hardware sensors are grouped in different sections for quick access and a cleaner look. The widget has been designed to save precious space in the Notification Center, showing clear and readable indications. All sensor readings are updated in real-time.

You can use the Configure button to open the Setup application and make any changes you want.
