Temperature Monitor is an application to read out all available temperature sensors in Mac computers. The program can display and visualize measured values in a large variety of fashions. The application supports the following operations on the measured readings:
- display in a default window
- display in a floating window
- tabular display in an overview window
- display in the menu-bar
- display of a maximum of two readings in the Dock
- graphical display of short-term and long-term history curves
- speech output of readings
- export to text files
Moreover, the application can display additional technical information about your computer. Among other information this includes:
- Processor type
- Processor and bus frequencies
- Manufacturing information
Of course, the application can read out the data only if your computer is equipped with the necessary sensors, and if Mac OS X can access them without needing third-party device drivers. Beginning in summer 2002, Apple has begun to massively drive forward the use of monitoring probes in the PowerMac series, the Xserve series, and in portable computers. Some models are equipped with 38 and more sensors. But Temperature and Hardware Monitor can detect sensors on many older systems as well if they are available.
We try to detect all sensors on as many Mac computer types as possible. However, a prediction which sensors are available in which models is not possible, because Apple very often releases "silent product updates", where the hardware equipments of some models are changed but the names are not (specifications are"subject to change without notice"). The particular graphics card and hard disk configuration used is also important because these parts can include independent sensors, too.
Please note that Apple does not support an official or standardized way of reading out sensor data in Mac OS X (the only exception is the Server Monitor application for the Xserve series). Moreover, there is no documentation or other technical note about the individual function of the sensors. For this reason, the development of Temperature Monitor and Hardware Monitor is very costly because the necessary data has to be determined by reverse engineering and tests run on a variety of computer models. Please support the development of the applications by purchasing a registration key for Hardware Monitor.
