I have a Macbook Pro running 10.9.3 (13D65), Boot ROM Version: MBP55.00AC.B03 SMC Version (system): 1.47f2
The fans are always running at full rpm and the kernel task used to take up 90% of the cpu till I found a fix that said to remove a plist entry specific to your Model Identifier. The plist was inside /System/Library/Extensions/IOPlatformPluginFamily.kext/ Contents/PlugIns/ACPI_SMC_PlatformPlugin.kext/.
This helped the kernel task problem, however the fans are still are running at highest the rpm possible. Recently a new problem appeared, now my Mac will randomly go to sleep mode on its own. I have tried resetting the SMC, but this has made no difference. I tried setting the sleep setting to never but it had no effect. I also tried the apps Caffeine and NoSleep, but they've had no effect either. Is this an SMC problem and if so how can I diagnose the damage? Does somebody know where on the logic board the SMC is, just to check it for corrosion or some sort of damage?
Update: http://pastebin.com/iYxwCi0W EtreCheck on Mavericks Also, I tried to fix the sleep problem by changing the pmset sleep to 0, it worked for a while but its rebooted on its own two times now.
Update: The pmset doesn't really take, however it hasn't restarted on its own anymore. Also the fans are now sometimes running at 230 rpm!
