I tested this with a Mac OS 10.15 virtual machine and installing Emacs from the following sources: * emacsformacosx.com * Homebrew: ** brew cask install emacs: I was not able to complete the installation for some reason but it is the same as emacsformacosx.com if I understand correctly ** brew install emacs-plus ** brew install emacs-mac * Mac Ports ** sudo port install emacs-app ** sudo port install emacs-app-devel ** sudo port install emacs-mac-app On the other hand, cursor tracking worked correctly in e.g. the Safari browser. So I guess the Mac port of Emacs does not have the "special code to move the system caret in sync with the cursor" that the Windows port has.
