If possible I would wait to do this until Line 6 officially supports Snow Leopard. See http://line6.com/community/groups/mac-osx-snow-leopard-user-group

I don't know if you need to re-register Line 6 gear when you change computer operating systems. You may not need to.

If you do need/want to, you can log in to your Line 6 account, go here:

http://line6.com/account/registergear/

and hit the Remove button for each piece of gear you want to un-register. Then, on your mac computer, log in again, go to the same web page and re-register the gear.

  Please be aware that Snow Leopard is not currently supported, but there is a “beta” driver available for you to use.  You will need to remove your current Line 6 driver using the "driver removal" application under Line 6 applications, then load the latest driver directly from the Line 6 website.  See the following links for more information on the current status of Snow Leopard:
