In TidBITS 429, the excitement of new PowerBooks and a forthcoming PalmPilot MacPac caused Managing Editor Jeff Carlson's personal wires to suffer a temporary short. It had been reported by many sources that the low-end processor for the PowerBook G3 series is a PowerPC 740 (See "Apple Hardware Strategy: Alluring PowerBooks and iMac"). In fact, Apple's Developer Note released on Monday confirms that all of the PowerBook models are running on the PowerPC 750 chip; the 233 MHz version's main difference is that it lacks a backside cache. As for the PalmPilot gaffe (see "Claris Organizer Reincarnated as PalmPilot MacPac"), several readers pointed out that the adapter offered in the MacPac enables you to connect to a Macintosh's serial port, not the ADB port.
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
