How can I change the currency in my Daylite estimate?

Daylite will display the currency based on your Mac System Settings. The currency type cannot be amended via a preference in Daylite.

To change the currency type, go to Apple System Settings > General > Language & Region > Region.

From here you can change the region to display the associated currency.

When you have made the change, you'll need to quit Daylite and relaunch it for the changes to take effect.
