MathType on a Mac

I've not done this work personally, but I wonder if Brandy Benedict's free book on Apple Books, Pretty Math, might be helpful to your team in this transition?

This books looks great. Thank you. I'd love to give our teachers a solution to at least bring their current documents over to the iSuite then be able to edit instead of starting over.

This article seems like it might be helpful: https://docs.wiris.com/mathtype/en/mathtype-office-tools/support/mathtype-support-notices/support-notices/transferring-documents-between-windows-and-macos.html

It appears there's a way to convert the format of equations when moving from Word to any application on a Mac. I may be reading the article incorrectly, but hopefully this provides a solution for your teachers.
