With a current original or upgrade licence, simply download the latest version of Tinderbox onto your new compute and register as normally.
If your licence for free updates has expired the process is the same except you should install the last version that your licence allows. If you no longer have the installed for that version, email Tinderbox support and ask for the download URL for your version.
Note the limitations on using the same licence on multiple computers.
Other aspects to consider:
- Preferences file. This is in
~/Library/Preferences. That folder will contain a preferences file and (if used) a Tinderbox user dictionary. - Configuration files. If you have customised badges, colour menus, etc., or have a set of favourite files, check your configuration files which are at
~/Library/Application Support/Tinderbox/. The latter folder can also be opened from the Tinderbox Help menu.
