MathType 8 is expected to be released at some undisclosed timeframe in 2021 and it is expected to support macOS Catalina and Big Sur. MathType 7 is only compatible with macOS 10.14 or earlier. There is an equation editor built into the free, 64-bit LibreOffice 7 though, and a version of MathType 7 is compatible with Google Docs from the Add-ons drop down menu.
We are fellow users, and only Wiris, the owners of MathType have control over future MathType product compatibility with macOS.
