How Loud Are Your Mac's Fans?

When they get hot, Macs turn on various internal fans to keep components cool. The noise can be annoying, but just how loud is it? If you have an iOS device with a built-in microphone, you can download one of many free sound meter apps (search on decibel in the App Store) and see if you're subjecting your ears to a truly unreasonable noise level.

 
 

Firmware Restoration CD 1.8

Send Article to a Friend

In keeping with past efforts, Apple has released a Firmware Restoration CD for early 2009 Mac Pro and Xserve models. The CD can be used to restore your computer's firmware in the event of an unsuccessful or interrupted update, though if that's already happened, you'll need to download the disc image and create a CD on another computer or bring your machine to an Apple Store or Apple Authorized Service Provider. The CD can be made on any Mac, but can be used only on the supported models. (Free, 22.5 MB)
