MacUpdate has introduced MacUpdate Desktop 6 (http://www.macupdate.com/desktop), a Mac app that leverages the MacUpdate app directory to provide one-click Mac app installs and updates.

The app also features a scanning engine that notifies you of updates to your installed apps. It requires a free MacUpdate account and provides access to titles not available in the Mac App Store.

MacUpdate Desktop 6 is available now as a free download. Users can take advantage of unlimited one-click installs of apps at MacUpdate.com, and one-click updates for up to 5 apps on the Mac per month. For US$20/year, an unlimited number of apps can be updated in addition to other premium membership benefits.
