Brett Terpstra has released Marked 2.3, which sandboxes the Markdown previewer in order to bring it to the Mac App Store. While Marked 2 replaces the original Marked app in the Mac App Store, Marked 2 is not a free update — though it is on sale for $9.99 for a limited time (both from the Mac App Store and the Marked Web site). The update now supports GitHub Flavored Markdown for the app’s Discount processor option, preserves bookmarks across refreshes and style changes, adds highlight navigation and highlighted word counts, fixes a problem with reading the most recent file in a folder, improves handling of unreadable and renamed files, and fixes an issue with initial file monitoring when opening in an external editor. Because Marked 2 is sandboxed, previously opened documents may require new permissions. Marked 2 doesn’t currently support OS X Yosemite, but Terpstra promises it will be added soon. ($9.99 new on sale for a limited time, free update, 16.7 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.
