### Event: 'thermal-state-change' _macOS_
* `state` string - The system's new thermal state. Can be `unknown`, `nominal`, `fair`, `serious`, `critical`.
Emitted when the thermal state of the system changes. Notification of a change
in the thermal status of the system, such as entering a critical temperature
range. Depending on the severity, the system might take steps to reduce said
temperature, for example, throttling the CPU or switching on the fans if
available.
Apps may react to the new state by reducing expensive computing tasks (e.g.
video encoding), or notifying the user. The same state might be received
repeatedly.

Notification of a change in the operating system's advertised speed limit for
