I’ve often wondered why my Macbook needs to growl every time I open the lid to wake it from sleep. Granted, I’m a little grumpy in the morning, but I don’t grind my superdrive like I’m trying to break it, now do I. Thankfully there’s a firmware update that will fix the problem without too much trouble.

The update includes some AirPort changes as well to help with connection issues. The update is simple enough. Just run your software update and follow the instructions. For this one you’ll definitely want the machine to be plugged in, just to ensure no interruption. Don’t worry too much about the intimidating warnings – the update’s not actually dangerous.

From there, your computer should be nice and quiet every time you open the lid.
