![]() The application has to respect this information and cannot change this. If you update to such an operating system, Mac OS X might qualify your processor as "not capable of providing temperature readings" although it was accepted in earlier versions. Because - as mentioned before - this technology is very inaccurate, Apple has tightened the checks in the latest operating system versions whether the processor is capable of measuring temperatures or not. No, in this case you are using a processor with TAU. The application has to respect this information and cannot change this.Īfter an operating system update the CPU temperature is no longer displayed. If your computer contains a processor with TAU but is not displayed by the application as software sensor with the name "Mach Kernel", Mac OS X has detected your processor as being "not capable of providing temperature readings". Up-to-date versions of the G4 series no longer support temperature measurement on the chip die. Due to this problem, the processor manufacturers have disabled the TA Units for later product generations. For IBM G3 processors there can even be a difference of 20 degrees Celsius (68 degrees Fahrenheit) between the measured and the true values. Motorola specifies that the readings supplied by such processor types can be off by 12 degrees Celsius (21,6 degrees Fahrenheit) from the actual values. However, this technology is very inaccurate and only works correctly if each processor is calibrated. This is a technique to acquire temperature values directly on the chip die and compute it by the processor itself. Some older G3 or G4 systems can be equipped with processors containing a so called " Thermal Assist Unit (TAU)". Not the operating system but a self-contained control device monitors the readings in this case. In a few cases, sensors are indeed available, but they are not accessible by Mac OS X. Computers built by Apple before 2002 are usually not equipped with sensor technology and therefore cannot be supported. I wonder if my iBook fan stopped working because some OS X update decided there was no way to know the temperature on this machine!. PowerPC 970 (G5)The Temperature Monitor FAQ has some interesting information about the history of Mac temperature measurement, and how OS X has changed over time.Your Macintosh system is very likely not capable of providing temperature values if it has no temperature sensor and uses one of the following processors: It is very likely that your hardware is capable of providing temperature values even if it has no temperature sensor if your computer uses one of the following processors: ![]() Your only chance is to let the software analyze your particular computer. ![]() Unfortunately, this means it is impossible to predict if Temperature Monitor will run correctly on your hardware. The computers known as "iBook (Late 2001)" may have a PowerPC 750 cxe v 2.4, or a PowerPC 755 v3.1 inside, and so forth. For example, in the product series known as "Power Macintosh G4 Cube", some systems are capable of providing temperature values and others are not. Apple appears to have shipped Macintosh product lines with same labels but different hardware inside. Power Macintosh G4 (Mirrored Drive Doors)įor all other models, there is no easy answer: Analysis of over hundred Macintosh systems shows that there is no one-to-one-relationship between model name and support status possible.This is why it's so hard to find something that works on my iBook: The following Macintosh models are definitely supported by Temperature Monitor, because they are equipped with dedicated temperature sensors: The most comprehensive sounding temperature monitoring solution yet.
