I haven't used any version Mac OS a lot, but one of the things I've never really liked is Finder. Like Explorer in Windows, it's a very basic file manager that probably serves most people well enough. However, I've never been "most people". In Windows I use Directory Opus and/or Xyplorer -- two commercial file manager replacements. The borrowed Mac I use to test software for Software Gadgets has a commercial replacement for Finder (Pathfinder), but it is a bit too "Finder-like" for me. I've discovered a (currently) free dual pane file manager for MacOS that seems nice: Moroshka File Manager.
