Parallels Desktop has been updated to version 9.0.23136 to improve support for the new multiple display functionality in OS X 10.9 Mavericks, enhance support for Finder tags, and provide OS X notifications when new email is received by Microsoft Outlook 2007 or later. The release squashes a bug that prevented external storage devices from reconnecting after either restarting or resuming a virtual machine or unplugging a device or media. It also provides enhanced battery life for MacBooks running Parallels Desktop 9, puts an end to annoying “device connect/device disconnect” sounds when resizing a window, and resolves an issue with dragging and dropping files from Linux to Mac OS X when running in Coherence. A quick update to 9.0.23140 resolves several crashing bugs in Mavericks. ($79.99 new, $49.99 upgrade, $39.99 educational, 356 MB, release notes)
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.
