+On Unix systems, the =locate= command is faster than =find= when searching the whole system, since it uses a pre-computed database, and =find= is faster if you need to search a specific directory instead of the whole system. On the Mac, we need to change the =locate= command:
+
+#+begin_src emacs-lisp
+  (when (equal system-type 'darwin)
+    (setq locate-command "mdfind"))
+#+end_src
+
+The advantage of =mdfind= is that is searches for filename /and/ its contents of your search string.

+Came up with a great way to search a project for Org-specific files, and wrote [[https://howardism.org/Technical/Emacs/org-find-file.html][an essay]] describing the approach and the code. The idea is that I can call =find-file=, but the list of files is not only the filename, but the Org =#+title:= as well as any tags located in the file.
