This isn’t news to me. Word has many fonts, but specifically the ones I need are missing. I have quite a bit of experience adding new fonts to Word, but I did it on a Windows laptop. Is there a simple, step-by-step guide for a Mac?

Just google it. I’m sure it’ll take you 10 seconds to find the answer and another 5 seconds to add a font. In the end, you’ve already spent more time here than needed. I don’t like it when people aren’t self-sufficient.

Well, everyone needs advice sometimes, and I don’t see anything wrong with offering guidance, especially since I just did the same recently. I know where to look for a guide to help with everything you need. Start with this article https://setapp.com/how-to/how-to-add-fonts-word-mac. Adding fonts to Word on a Mac isn’t much different from Windows, so follow this guide, and it should work fine.
