Important notice to keep MathType for Desktop working on your Mac
Since Catalina launch macOS has removed several components which MathType 7 and previous versions depend on. Unfortunately, MathType 7 - Desktop version - is compatible up to Mojave macOS. It will stop working if you update your macOS to BigSur or Catalina.
Given the nature of the development that needs to be done to make MathType compatible with Catalina and Big Sur, we regretfully inform you that we will not be able to release it in 2020. We are working to release MathType 8, a compatible version with current and future macOS, on 2021. MathType 8 will also include new functionalities.
Please note that this does not affect MathType for Google Docs, for Google Slides, MathType for Windows and Mac up to Mojave 10.14.6 or MathType online (for LMS and web based apps).
