How do I upgrade to TextExpander 6? (Mac) Owners of TextExpander 5 and earlier may sign up for a TextExpander account at a discount for an introductory period. Create an account on TextExpander.com. If you do so on a Mac where you have a previous version of TextExpander installed, when you setup billing for your TextExpander account, your discount will be applied automatically. If not, you may need to look up your old license number.
