Apple has released Logic Pro X 10.0, redesigning the professional audio app with a sleeker, darker interface. New features include Track Stacks for grouping related tracks, Smart Controls for adjusting multiple plug-in parameters at once, a virtual drummer (safe from spontaneous combustion!), and Flex Pitch for fine-tuning the pitch of notes. Released alongside the update is Logic Remote for the iPad, a free companion app to control Logic Pro X remotely. If you’re worried that Logic Pro X will be the disaster Final Cut Pro X was on initial release, we suggest reading veteran Apple writer and guitarist Jim Dalrymple’s thorough review. As with all Mac App Store apps, there is no upgrade discount; if you want to move up from the previous version, you must still pay full price. ($199.99 from the Mac App Store, 650 MB)
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.
