Important notice to keep MathType for Desktop working on your Mac
Since Catalina launch macOS version Catalina has removed several components which MathType 7 and previous versions depend on. Unfortunately, if you update your operating system to current macOS Catalina, MathType 7 or any of our older versions will stop running. Please be advised this macOS update is also affecting other applications.
Given the nature of the development that needs to be done to make MathType compatible with Catalina, we regretfully inform you that we will not be able to release it in 2020. But rest assured that, during this year, we will continue working to make our tool compatible with current and future macOS and to provide it with new functionalities.
Please note that this does not affect MathType for Google Docs, MathType for Windows and Mac up to Mojave 10.14.6 or MathType online (for LMS and web based apps).
