Recent updates causing PowerBook fan activity -- Apple's Battery Update 1.1, perhaps in conjunction with Mac OS X 10.3.2, seems to have caused increased fan activity on some PowerBooks and iBooks. Is it a glitch, or a way to cool down those hot aluminum PowerBooks? (11 messages)
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
