Typinator uses a "smart self installation" technique that makes installing and updating a breeze. Just mount the downloaded disk image and double-click the Typinator icon inside. Typinator will quit an older copy that may be running, copy itself to the Applications folder and launch the newly installed copy.
Important: Do not use application-cleaning tools (such as AppCleaner, AppDelete, AppTrap, AppZapper, CleanApp, CleanMyMac, iTrash, TrashMe, and similar apps) to remove the old version of Typinator before installing the new one. These tools erase all data that belong to Typinator, including your abbreviations and preferences. Just update Typinator as described above to preserve all your personal settings.
