Igor Pro on macOS 10.15 (Catalina) and 11.0 (Big Sur)

With Catalina, Apple dropped support for 32-bit applications, dropped the QuickTime framework that Igor uses to support most movie features, and added strict security features that prevent XOPs from running without special security certification ("notarization").

We do not consider any version of Igor Pro 8 to be fully supported on Catalina or Big Sur. However, we expect Igor Pro 8.04 to work with the caveats explained here.

A more thorough explanation of Igor compatibility with Catalina and Big Sur is on our News page here:
