Template Toaster for Apple MacOS
It would be nice if there was a version of Templatetoaster for MacOS.
The Template Toaster team is a smaller team and I believe creating a Mac compatible version would pull them away from making updates to the current Windows version of Template Toaster.
My suggestion to you is to buy a secondary Windows PC/Laptop for apps that are exclusive to Windows. You can normally find a decent one for just a couple hundred to four hundred dollars. That's what I do.
