after update to 10.10.2 - i am getting powerd message in the log every 30 seconds.

[tluck]

here is cut and paste from /var/log/system.log - is this a DSDT issue?

It seems this is a FakeSMC (key) issue.

[tluck]

This was fixed by adding the SMC key ACID into FakeSMC.

[Hs-Yeah]

@tluck Can you tell me how to add the SMC key ACID into FakeSMC ?

[tluck]

i added this key to the Keys section of FakeSMC.kext/Contents/Info.plist

                                        <key>ACID</key>
                                        <array>
                                                <string>ch8*</string>
                                                <data>
                                                ut7DNVAFEGM=
                                                </data>
                                        </array>

[Hs-Yeah]

@tluck Thank you! I added the Key and rebuild the kextcache but it didn't work. :(

[RehabMan]

It works -- @Hs-Yeah... you must have added it incorrectly.

Eventually, some version of this will appear in my FakeSMC fork.

[Hs-Yeah]

@RehabMan @tluck I added it here. Did I make it wrong?

My SMBIOS is set to MacBookPro9,2 and my AC Adapter is 90W.

[tluck]

that's seems right to me. if you look in About this Mac/System Report/Hardware/Power
does your AC charger Information look like this?

AC Charger Information:

Connected: Yes
ID: 0x0100
Wattage (W): 85
Revision: 0x0000
Family: 0x00ba
Serial Number: 0x0035c3de
Charging: No

[Hs-Yeah]

@tluck Nope, only

Connected: Yes
Charging: No

I think the ID things will not appear until I make the powerd message gone.

[tluck]

well then you really don't seem to have the ACID key there?
assuming your FakeSMC is in /S/L/E, you can force a kextcache rebuild by:

sudo touch /System/Library/Extensions

and then restart.

or to read your keys run:

smcutil -l | more

[Hs-Yeah]

@tluck @RehabMan
I reinstall the FakeSMC.kext with my edit of Info.plist in it using the Kext Wizard and then using the command @tluck told me to rebuild the kextcache.
After reboot the problem was fixed.
Thank you!
