Well, I found some info here: http://e-www.motorola.com/files/32bit/doc/app_note/AN1800.pdf But I'm missing something :-( I guess. Most likely licensing is in the way. Perhaps someone knows better. Also found this: http://mail-index.netbsd.org/port-powerpc/2002/03/03/0000.html But nothing more to it. I'm sure it's possible. Under Mac OS 9, many software products did it, so there is a way to interface to the hardware and retrieve the info. The question is how under OS X? More interesting is it apparantly has a PPC 750: http://www.bresink.de/osx/TemperatureMonitor.html Seems supported. Shawn Erickson wrote:

Is there a way to get the processor temp via terminal in OS X?

I'd like to script some method to record the processor temp of my old

beige G3.

Note the following email... it may give a avenue but as other have

stated no defined interface exists.

Hi,

I've been trying to figure out where the readings for the G5

temp sensors can be located (also for Xserves). I'm assuming

OS X has this info in a way where I can just 'cat' it (since

everything on nix is treated as a file). Or is there a

framework that I'm not aware of that allows me to access this

info (still new to programming on OS X ;)? Can someone point

me to the right direction?

I hopefully can get on the path at least... (don't know that

answer myself at the moment)

Try running the following command: "ioreg -b -n IOHWSensor"

You will see entries like the following...

| | | | +-o temp-sensor <class IOService, registered, matched,

active, busy 0, retain count 6>

| | | | +-o IOHWSensor <class IOHWSensor, registered, matched,

active, busy 0, retain count 6>

| | | | {

| | | | "current-value" = 1847296

| | | | "polling-period" = 18446744073709551615

| | | | "location" = "DRIVE BAY"

| | | | "type" = "temperature"

| | | | "IOClass" = "IOHWSensor"

| | | | "IONameMatched" = "temp-sensor"

| | | | "version" = 1

| | | | "zone" = <00000001>

| | | | "IOProbeScore" = 0

| | | | "IOMatchCategory" = "IODefaultMatchCategory"

| | | | "IONameMatch" =

("temp-sensor","voltage-sensor","current-sensor","power-sensor","adc-sensor","fanspeed-sensor")

| | | | "CFBundleIdentifier" = "com.apple.driver.AppleHWSensor"

| | | | "IOProviderClass" = "IOService"

| | | | "sensor-id" = 4

| | | | }

Using IOKit methods you can scan the IO registry programatically

to find the above information (see IOKit / Kernel document on

Apples developer site). You can also get a hold of the driver

instances (instances of IOHWSensor) which may or may not provide a

user client that will allow you directly communication with

whatever API it exposes. I don't know the units or encoding for

current-value...

Also sysclt may exist for the above information... (I don't know

myself)
