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.

Using iDVD 3.0.1 on Non-SuperDrive Macs

A few weeks ago, Apple released iDVD 3.0.1 Update, an apparently minor patch that provides, in Apple's brief description, "improved performance and stability for encoding, burning, and managing your iDVD projects." (The updater is a 4.1 MB download.)


What Apple didn't mention at the time, but recently revealed in a Knowledge Base article, is that the update makes it possible to run iDVD 3 on any Macintosh with a PowerPC G4 or G5 processor - not just Macs with a built-in SuperDrive, as previously required. Of course, you won't be able to burn the final DVD disc on a non-SuperDrive Mac, but you can build projects and encode them in preparation for burning on another machine.

Unfortunately, you can't purchase a copy of iLife and install it on your Mac; the installer won't install iDVD 3 without a SuperDrive present. (I wasn't able to test to see if a recent boxed copy of iLife includes iDVD 3.0.1, and whether that would install on any Mac; since its introduction, the iLife package has been updated to include iTunes 4. However, I doubt that copies with iDVD 3.0.1 would have made it into the retail channel yet.) Instead, you must copy the iDVD 3 application folder from another SuperDrive-equipped Mac, then run the iDVD 3.0.1 update to make it work.
