kernel errors after updating to 10.7.4

Same problem here. I went to Activity Monitor and quit smcFanControl and the problem immediately stopped. From the rest of this thread, it sounds like Apple must have changed the fan control interface in OS 10.7.4 and just about any app that reads the fan gets this error.

I'm getting the same error message, every 3 seconds, really annoying and totally useless in my opinion, who cares about logging access to a sensor that doesn't exist?? Anyway, I've dropped a note at the devoper's home page http://www.eidac.de/?p=207 maybe you can, too.

In my case CPUled app was the root cause; after stopping it the message was gone

I updated to 10.7.4 on Sunday and yesterday my MBP froze (it didn' actually froze, I could move the cursor but it looked weird an I couldn'd do anything), so I forced it to shutdown. Then it got stucked at the grey screen, with the wheel spinning until it stopped and nothing else. Then I was able to boot in safe mode, but this was my screen when i did it.

I tried to restart but it was impossible to boot up again, even in safe or recovery mode. Today, during an inconclusive safe boot I've got this

I've done the PRAM and NVRAM reset and then I've been able to boot in recovery mode. I did nothing else, just restart normally and it worked. Now my fear is if i'm going to have these boot and graphic errors again. ¿Are these the same errors you've been experiencing? ¿Should I try replacing the AppleSMC.kext?

Thanks

I have replaced and works very well! No problem! Good luck.

Thank you. Relacing the 10.7.4 file with the 10.7.3 file eliminated all console errors. This was driving me nuts!

You are Welcome 🙂 Glad to help !

frankbullitt did you manage to fix it? I ave a somewhat similar experience.

This happened after it was frozen and restarted..

Yeah, I kinda fixed it, I´m sorry I didn't post anything after I did it and thanks to Laris and everyone else.

The thing is, it works but, my mac at least, still does strange things. Let me explain. After I replaced the kext, I booted in safe mode, it worked, so I shut down and restarted in normal mode. It worked again. Next day, normal boot, it hanged again at the spinning wheel. Safe boot, it works, restart, normal boot, It works, magic. For some days it was impossible to do a normal boot without doing a safe boot previously, I didn't understand it. One day I forgot to press shift key at boot screen and I thought it was going to hang up... but it didn't. Magic. After that, it takes lke a year and a half to start up, it used to take only a year before. Maybe this is only happening to me, I don't know. Now I have some time i'm going to make a clean OS X install, maybe 10.7.3, maybe going back to 10.6, I'm not sure.

That's my story, I hope it helps you (but I don't think it's going to).

Just for the record: the problem with smcfancontrol flooding the console with errors is gone in 10.8.

Yes, i confirm that ! 🙂

DO NOT manually downgrade the kernel extension just because the new version exposed a bug in one of the applications using it

100% agree with this. The problem in my case was a combination of Fan Control and iStat. I removed iStat from the dashboard, and removed Fan Control as documented elsewhere in this thread. Problem gone.

Just as an experiment I re-installed the iStat widget. There was a flurry of SMC errors when it installed, but after that all was clear. I assume it disables checking for any SMC calls that return errors when it is first installed. So I can still have the useful iStat widget, and no SMC errors in the log. Nice.

Well I followed Alfonso Garcia's comment below and it fixed my error instantly.

I've been having same problems with that strange kernel error. I repaired permissions and it didn't work, so I uninstall iStat Pro Wiget, FanControl and I deleted the "FanControl Daemon" folder from \Library\StartupItems

and now I don't have any problems! 🙂

Hope my experience helps all of you!

I didn't even know I had the /Library/StartupItems/FanControlDaemon until I looked! This was the problem. It was from 2007. Deleted, rebooted and the error messages are gone!
