AppleSMC.kext-10.7.4 causes smcReadKeyAction error in consol

[Dewitts]

Hey guys I updated to 10.7.4 2 days after it came out and yesterday I had a look on console under Kernel.log and noticed 3 almost identical error messages being posted every 5 seconds.

May 20 15:31:44 Christophers-Mac-Pro kernel[0]: SMC::smcReadKeyAction ERROR TC0D kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff800b540600
May 20 15:31:44 Christophers-Mac-Pro kernel[0]: SMC::smcReadKeyAction ERROR F0Mn kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff800b540600
May 20 15:31:44 Christophers-Mac-Pro kernel[0]: SMC::smcReadKeyAction ERROR F1Mn kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff800b540600

It turns out this isn't just hackintosh related as it is all over the official apple support forums such as HERE.

There seems to be a problem with the 10.7.4 version of AppleSMC.kext so as suggested I have extracted the kext from the 10.7.3 combo update (as I no longer have a 10.7.3 install) and reinstalled it using kextbeast.

If someone with the knowledge know's what apple screwed up and can fix this kext then you'd be helping a lot of people but anyway i've attached the 10.7.3 kext for those of you that have this problem and don't have a 10.7.3 install to copy the kext from.

Kudo's for Mickey1979 for finding the thread with the solution in the apple support community forums.

Re: 10.7.4 AppleSMC.kext error

I've got the same message, but only two errors repeatedly :

May 21 18:22:52 Mac-Pro-de-Olivier kernel[0]: SMC::smcReadKeyAction ERROR F0Mn kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff802f574400
May 21 18:22:52 Mac-Pro-de-Olivier kernel[0]: SMC::smcReadKeyAction ERROR F1Mn kSMCBadArgumentError(0x89) fKeyHashTable=0x0xffffff802f574400

N.B: 10.7.4 with AppleACPIPlatform.kext from 10.6.8.

Re: 10.7.4 AppleSMC.kext error

did you solve it by replacing the AppleACPIPlatform.kext?

Re: 10.7.4 AppleSMC.kext error

I replaced the AppleSMC.kext and it solved it for me as instructed in the link in the 1st post.

No need to rollback the drivers... update fakesmc.kext to the latest version and no error.
keep the 10.7.4 one.

Hi Guys;

I had this error too, "SMC::smcReadKeyAction ERROR TC0D".

As noted in Dewitts' post 1, installing AppleSMC.kext version 3.1.1 ( from Lion 10.7.3 ) fixed it. FakeSMC.kext version 4.2.0 did not stop the SMC errors.

Ethernet not waking from sleep led me to look for error reports in Kernel cache using Console. I had tried rebooting the router, and several other things I know to do, but none fixed it. After installing the AppleSMC.kext I also had to reboot the router.

After several sleep/wake tests the problem is fixed and there are no SMC errors.

This problem affected other boot drives with Lion 10.7.2 on the same computer, the system would lock up about 5 seconds after waking from sleep. I don't know if the source was at the router or SMC settings stored on the motherboard. As above the issue is fixed there too.

Thanks Dewitts
