Mac OS X 10.1.3 Released -- Apple has released the Mac OS X 10.1.3 update as a 17.3 MB download via Software Update. (If you're running Mac OS X 10.1 or 10.1.1, a separate 38.4 MB combined update to 10.1.3 is available.) As with previous updates to Mac OS X, this one is well worth getting, and kudos to Apple for providing decent release notes. Along with reliability improvements, Mac OS X 10.1.3 includes more drivers for CD burners and digital cameras, enables DVD playback on external VGA displays connected to PowerBook G4s, turns video mirroring on by default when a PowerBook connects to a new display, and offers improvements to iTunes with full screen visualizers. Networking security received attention as well, with login authentication support for LDAP and Active Directory services, an update to OpenSSH 3.0.2p1, WebDAV support for Digest authentication, and support for SSL encryption in Apple's Mail application.

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.
