@TechUST, Thanks for posting in Q&A. Based on my researching, I find there's no desktop version of Visio for macOS. To use Visio on MacOS, you can work on Visio files on a Mac in your web browser. Here is a link with more details:

For Microsoft Project, it is designed for windows. And it wasn’t designed for Mac computers. So I don't find the link to download the app for MacOS either.
