Actually, there would be LOTS AND LOTS of updates of a recent MacTeX-2020, namely all released between last April and today. In fact, just this morning there were many new updates.

Howdy,

One more thing... make sure you typeset using pdflatex (or xelatex) and NOT latex since it can't handle .png graphics.
