Column-navigation file manager

If you want a file manager with column navigation (macOS-alike) in linux, Pantheon File Manager is probably the best option. Pantheon File Manager is part of the Pantheon desktop, developed for elementary OS using Vala and the GTK3 toolkit. In Ubuntu and derivatives (e.g. Linux Mint) it’s as easy to install as:

sudo add-apt-repository ppa:elementary-os/stable
sudo apt update
sudo apt install pantheon-files

Done! You just need to search the app called ‘Files’ to launch it. It also displays a message asking if you want to make it the default file browser.
