Whilst fine for most purposes, systems administrators and other power users can often become frustrated with the limitations of Finder, the native Mac OS file manager. Fortunately, help is on hand in the form of Double Commander - a popular, open source, cross-platform file manager. Inspired by Total Commander, this valuable tool allows users to browse files side-by-side in two separate panels. There are a range of powerful features, including Unicode support and an internal text editor, and the software is able to run operations in the background.
