Lightburn will not open on Mac OS 2021

When I try to open the lightburn software i get the message “there is no application set to open the document Material tester.lbrn” then it says “search the app store for an application that can open this document or an existing application on your computer” how do i fix this???

Did you associate the .lbrn file extension to the LightBurn app? This is how you tell the OS to open LightBurn and the associated LBRN file when you double-click those files.

No, i will do that right now!
