Just to add to your testimony, Karthik:

On macOS some of the Emacs keybindings also work system-wide. You can e.g. use C-a/e, C-k, and C-n/p/f/b in every macOS text field, like e.g. in browser text fields. This is one of the main macOS features I miss on GNU/Linux. (Actually, that subset of Emacs keybindings even works on iPad with an external keyboard.)

Aside from keybindings, there are also some packages that provide deeper integration with macOS. For example, org-mac-link can save Org-mode links to currently open emails in Mail.app. And the built-in `C-x m` can author emails that are then sent to Mail.app for further processing, if you’re not able to use mu4e and similar (e.g. strict Exchange email servers).
