Asked at PMUG – My MacBook is running the fans a lot

At PMUG last night, someone asked what to do about their fans running non-stop on a MacBook.

Aside from bad sensor, or a runaway application, we told the person to update their SMC firmware. But where do you get that?

Well luckily Apple just redesigned the Apple Support page and I really like it.

From there, you can choose MacBook from the popup on the left, and end up here

Wow, right on the main page, every bit of information we needed. Nice!
