Apple Releases Power Mac SuperDrive Update -- Apple has posted an important update for owners of older SuperDrive-equipped Power Mac G4 computers (specifically, the Digital Audio, Quicksilver, or Quicksilver 2002 models, but not the Mirrored Drive Doors model, to use Apple's insipid model identification scheme). The Power Mac G4 SuperDrive Update corrects a problem in the drive's firmware that could cause the drive to overheat when using new 4x speed DVD media (for more details, see "Apple Posts Important iMac SuperDrive Update" in TidBITS-653). The update is currently available only under Mac OS X; Mac OS 9 versions will be posted shortly, according to Apple. [JLC]
Go Back and Forth Fast in Preview
If you're reading a PDF in Apple's Preview software, and you follow a bookmark or an internal link to move around within the PDF, you can quickly return to where you were by pressing the keyboard shortcut Command-[ (that's Command-Left Bracket). Or, you can choose Go > Back.
The command works iteratively, so you can go back to just the previously viewed page or if you issue the command again, to the page before that, and so on. There's also an equivalent Go > Forward (Command-]).
