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.

Apple Silences Mac OS X 10.4.10 Popping Sounds

Send Article to a Friend

If you installed Mac OS X 10.4.10 before 02-Jul-07, you probably got version 1.0 of the update, which caused some Intel-based Macs with external speakers to experience "popping" sounds. PowerPC-based Macs weren't affected. (For details on what was fixed in Mac OS X 10.4.10, see "Mac OS X 10.4.10 Released," 2007-06-25.)

Apple has now released a variety of updates to address this annoying problem. If you haven't yet installed the Mac OS X 10.4.10 Update on an Intel-based Mac, you'll now see a fixed version 1.1 in Software Update; it's also available as a standalone download in both delta (72 MB) and combo (297 MB) forms. Those who have already installed Mac OS X 10.4.10 will instead see Audio Update 2007-001 in Software Update; it too is available as a 660K standalone download.
