Temperature Monitor is an application to read out all accessible temperature sensors in Macintosh computers. The program can display and visualize the values measured by Mac OS X in a large variety of fashions. Among others, the following operations are supported:
- display in a default window
- output in a screen display in front or in the background of the screen
- tabular display in an overview window
- display in the menu-bar
- display in the Dock icon
- graphical display of short-term and long-term history curves in an unlimited number of windows
- speech output
- display of minimum and maximum values
- export to text or CSV files
Moreover, the application can display additional technical information about your computer. Among other information this includes processor type, processor and bus frequencies, and manufacturing information.
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. Starting 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.
Temperature Monitor tries to detect all sensors on as many Macintosh 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. The particular graphics card, hard disk configuration and operating system version is also important.
- Added support for a large number of new temperature sensors of Intel-based
Macintosh systems. This includes thermal diodes monitoring the processors
externally, GPU sensors, drive bay sensors and FB-DIMM sensors of the Mac
Pro, etc.
- Added new feature to combine multiple history windows, making it possible
to put sensors with different quantities into direct relation with each
other. The user can define overlays for any selection of graphs.
- Readings of sensors which have raised an alarm are now displayed with
warning markers in the sensor window, the screen display, and the menu-bar.
- The display of sensor readings in some output channels has been optimized
further. No additional space is added in front of the readings which consumes
less screen real-estate and enhances the appearance in windows where left-aligned
layouts were selected.
- Corrected a problem where the curves of history graphs could show a flicker
effect under very special circumstances.
NOTE: Some specific sensor location labels for Intel-based systems are subject
to change and may not be final. Compatibility Reports for the new Core 2-based
Mac series created via the Help menu of Hardware
Monitor are welcome. Intel
Xserve models are not fully supported yet. Support will be added when these
systems become available.
