I just tried without OHR.kext, Restart and Shutdown does not work.

Added the EC to my DSDT today. Here's the latest and greatest:

With the new fakeSMC I also see the +9000 degree CPU A temperature diode in Temperature Monitor.

[VCH888]

I tested the fakesmc.kext from the 1st post on 945GCM-S2L, E2180 @ 2 GHz.

I got CPU temperature in iStat about 48-50 C.  GB bios showed about 34-35 C.  Is this Correct?

Also, I used Temperature Monitor and it showed as a below picture.



CPU A Temerature Diode was very high.  I think this one was not correct.  If I didn't use the modified fakesmc.kext, CPU A Temperature Diode would not show up.

Thank you for your work.

The file in question is in FakeSMC source package. I presume you don't have Xcode installed (sorry if I'm wrong), so here is the same kext without the "key not found" log message.
fakesmc.kext.zip

As I checked today I still have the errors in my log

(kernel FakeSMC: key info not found VSFC, length - 6 .... and so on)

Thanks

10.5 version works fine, thx

As Tmongkol, a new temperature appeared in Temperatur Monitor Menu but the value is wrong lol here is a screnshot :

I don't see any difference betwin Temp Monitor and IStat temp

Here is also the FakeSMC console error messages when I launched IStat, some seem to be related to FanSpeed value (Fnum?) :

Just tested, and it works fine. The Temperature diode seems to be the temperature multiplied by 256.

Thank you, would be great to have the temp for each cores though.

About "CPU A Temperature Diode", looks like Temperature Monitor reads the same 2 bytes TC0D key, but big-endian, while iStat uses little-endian.
For example:
TC0D = <31 00>
iStat reads: 0x0031 = 49
Temperature Monitor reads 0x3100 = 12544

Looks like I removed the wrong log message ("key not found" instead of "key info not found"). I'll compile it again when I get home at night (GMT -3).

I used 100 for Tjmax value, and looks like your CPU's is 85, that's why you see the 15º difference. I'll look for a better way to do it.

TC1D, TC2D, TC3D appear as CPU B, C and D

This is from smc.0.01 :

Temperature sensors
-------------------
TB0T
TC0D
TC0P

Th0H
Ts0P
TN1P

ALV1 - Right 

Motion sensors

Thanks, I'll try to make it show temps for all cores.

[DieBuche]

an interesting read is this : http://apt.wikimedia...wmon/applesmc.c
It's an smc port for hardy, from line 87 on, it lists all the smckeys for temperature which can be accessed for the respective mac model.

but that's for a mac which already has an smc device!

[oldnapalm]

If someone want to, please test this. Should show temp for each core, and there's a "tjmax" key in Info.plist so one can change it's value.
Thanks.

Hi,
Checked the latest edit to your fakesmc.kext. Indeed shows 4 CPU temp values in istat menus. Left Tjmax @ 100 (default), which values seem correct with Q9550 CPU.
But friend, those messages about smckeys are still there in the log. All else seems to work okay.

Thank you.

Mate those are there with a purpose, the kext is not finished...
Wait until someone add debug option in plist, or you do the job if that upset you so much...

[sk1nhead]

working great here, thanks a lot oldnapalm for the updated kext.

Temperature monitor still shows 9000 degrees for diode A with this one. Anyone care to confirm?

I confirm it, but if you change the kext to work with Temperature Monitor, iStat won't work anymore.

I get these kind of readings, Temperature monitor application works, but all sensors show +5 degrees compared to VoodooMonitor or iStat.

Now I understand, thanks, that'll teach me to read..

Maybe Temperature Monitor calculates a different Tjmax value for your CPU?
Here it shows the same values as iStat and VoodooMonitor (except for diode temps which are 10000º+ as mentioned).

In Temperature Monitor preferences, under sensor tab, you can select "don't acquire readings from this sensor" for the ones showing wrong values.

Seems to be defined to 105 for some reason.
