Learn how MacUpdate Desktop makes installing apps from one-click easy.
Next time, install Sloth with 1-click

Learn how MacUpdate Desktop can install apps on MacUpdate with the simple click of the Install apps with MacUpdate Desktop icon. Plus, keep all your apps updated.

Sloth is an OS X application that displays a list of all open files and sockets in use by all running applications on your system. This makes it easy to see which apps are using which files and sockets.

Sloth is basically a GUI on top of the powerful lsof command-line tool. The output of lsof is parsed and shown in a searchable, filterable table view with some convenient user-friendly functionality, such as revealing files in Finder, killing a file's owning process, etc.
