    Has anyone figured out a fix for this yet? The remedy of removing that kext worked but it later started causing the laptop to overheat. Please someone tell me Apple has put out a fix or someone has figured out a work around? I'm currently overseas and not near an Apple store, so I can't send it in. I use this laptop for work and this issue is severely impacting it in a negative way.

    Sounds like SMC problem. Can you try a SMC reset!?

    Yep, tried that. No luck.

    This issue is really baffling. Running on battery it's fine but as soon as the charger is connected it goes nuts.
