Nimble Commander ➹

Nimble Commander is a Midnight-Commander style file manager for the Mac that sports the traditional dual-pane interface and extensive keyboard shortcuts. It offers features such as file previews, batch renaming, etc. and makes file management tasks more efficient when doing keyboard-driven workflows.

It is available on the Mac App Store, but you might prefer to do brew install --cask nimble-commander instead to get a non-sandboxed version with more features (including a built-in terminal and the ability to browse remote servers).
