Lemkesoft has released GraphicConverter 9.2, which now includes a new feature that regularly verifies images on NAS devices (via a background task). The graphic conversion and editing utility gains sharpen, burn, and dodge brushes, an export to Apple TV that keeps file order, display of animated GIFs during slideshow, the capability to access tools in new submenu, and a golden ratio display. The update also optimizes the speed of PDF multipage editing if ZIP or JPEG compression is used, improves rename options, fixes a bug when saving GIF loop values, and improves batch multiscale options. ($39.95 new from the Lemkesoft Web site or from the Mac App Store, 228 MB, release notes, 10.7+).
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.
