Igor Pro on macOS 10.15 (Catalina)

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 recommend that you avoid Catalina if you need to use Igor Pro. However, we expect Igor Pro 8.04 (currently in beta) to work with the caveats explained hereWe do not consider any version of Igor Pro 8 to be supported on Catalina yet, though we will do our best to fix Catalina-specific bugs.

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