Does your MacBook Core 2 Duo make an annoying high-pitched squealing noise when at low system usage? Mine did, so I called AppleCare. A half hour of waiting on hold and an hour troubleshooting had me headed to the local Apple store to get my baby looked at.

So this “genius” assumes I’m having problems with Leopard (apparently, nobody got the memo that v. 1.0 products are always a bad idea), and seems relieved when I tell him no. I explain the problem, and after trying to hear the noise in a busy mall, he finally disappears for about 10 minutes in back.

He comes back and says “Yeah, we can hear the noise. However, all our other macbooks back there make the same noise. Sorry, there’s nothing we can do for you.” WHAT?! Nothing you can do? Thanks, I’ll just get a headache every time I take this thing to the library.

Honestly though, I can’t put up with that. After poking around on the net, it looks like this is Intel’s C4 sleep state problem, and appears on C2D chips everywhere. It also happens on MacBook Pros, and some guy made a little utility that fixes it. The utility says “DO NOT USE THIS ON ANYTHING BUT A MACBOOK PRO.”

But I was desperate. So I installed in on my MacBook. The problem is gone!!!

I’ll let you know if it melts my MacBook, but for now I’m just really really happy. If you want the fix, it’s called “Shhmbp”. Go ahead, just click here and fix your MacBook C2D whine problems.

Oh, yeah, and I’m not making any safety guarantees here, just stating that it worked on my C2D MacBook (2.0 GHz, GMA 950). So don’t come crying to me if it don’t work for you.

**********Update, many months later****************
Whine is still gone, still no problems with my MacBook! Looks like this one has no apparent ill effects on a plain jane MacBook.
