This will ensure a factory-default software environment in which you can try applying the firmware update.

Then install a fresh copy of OS X to the drive. Attach an external hard drive and reboot the system with Command-R held down to load the recovery drive. You can search for the update on this page or, for more recent updates, you'll see them listed at the top of the page.Īs a last resort, you can try installing the firmware update from a fresh OS installation. Then try downloading the relevant updater manually from the Apple Support Downloads page and run it. If not, remove any residual traces of past update attempts by opening the System > Library > CoreServices > Firmware Updates directory and moving any items in this folder to the desktop.

Apple Care had me upgrade to Mavericks, which caused it to overheat more quickly, but they didn't know how to reinstall the SMC firmware.ĭoes anyone here know how? Trying to install the current one doesn't work. After it didn't work, they suggested calling Apple Care. With that, I went back to the Genius Bar where they tried to install the SMC firmware from a thumbdrive. He said that since the third-party software would drive the fan, it wasn't a hardware problem, but that it was probably something corrupted in the SMC firmware. Later, I spoke with a friend who was conviently enough a project engineer on the Macbook Air and described the symptoms to him. I have intstead nursed it along using Macs Fan Control.
They offered to have the logic board replaced at my cost since it was three months out of warranty. I took it into the Apple store and while their diagnostic tests said everything was fine, I demonstrated to them how youtube would overheat it and the fan would never rev up. Things like watching youtube videos or going to websites with flash would cause it to crash. It later started to crash more often on the OS X side. It worked fine for the first year or so, although I did notice it crashed a lot while using Windows in bootcamp. This is my first mac and I assumed it didn't have a fan since I never heard it. I use this program frequently on my MBA computer and it really comes in handy, not only for temperature control but for many other reasons as well.Does anyone know how to reinstall the SMC firmware on a mid 2011 Macbook Air? This computer's fan has never turned ran above 2000rpm (on it's own). The LED light gives you the ability to see if the fans are on or not. For example, it might be nice to know that the computer is cooling down quickly at the beginning of the day but you don't need the computer to be over-speedy heating up later in the day. I assume that the high fan speed is a precaution by the SMC as it cannot read the temperature.

I have observed that the sensor for GPU 2/B Die is 0/missing in TG Pro and istats menu. The program was a real lifesaver for some the older MacBook Pros my own 4.1 2.4Ghz Penryn runs easily between 60C & 70C and some run far hotter. The timer control allows you to set a time to remember each fan speed and then turn them on at the right time. I have a Mac Pro (late 2013) which I need TG Pro (or Macs Fan Control) to control the fan speed. SMC Fan Control just lets you increase the rpm ahead of any heavy workload or like when charging the battery you can add 1000rpm and help to keep the system a little cooler. It also has a feature called "low battery alarm" which will automatically turn the fans off when the battery is low and turn on again when the battery is full.Īnother cool feature of SMCfanControl is that it comes with both a light control and a timer control. To adjust fan speeds, you have to have administrator privileges. It does this by adjusting the minimum speed of the fan and by setting the maximum power used. The only thing you'll need to be careful about is keeping the computer on an incline so that there is proper air flow.Ī SMCfanControl allows you to control the fans in your Mac manually just to make it operate much cooler. You can even set up a timer to turn the fans off and on at set intervals.
My advice for people who run their programs all the time in a crowded room is to get a SMCfanControl utility that will not only turn their fans off when not needed, but will also automatically shut them off when the room temperature reaches a certain point. I've always had a problem with computers overheating, especially when running multiple programs at once, and I'm sure you've experienced the same problem I have.
