Emulate the Unix ls command in Emacs Lisp because the one in MacOS:
(with-eval-after-load 'dired (require 'ls-lisp))
(with-eval-after-load 'ls-lisp
(setq ls-lisp-use-insert-directory-program nil
dired-listing-switches
(string-join '("--all"
"--group-directories-first"
"--human-readable"
"--no-group"))))
Hide MacOS garbage files quietly.
(with-eval-after-load 'dired
(setq dired-omit-files "^\\.DS_Store\\|\\.localized$"
dired-omit-verbose nil)
(add-hook 'dired-mode-hook #'dired-omit-mode))
