Igor Pro on macOS 10.15 (Catalina) , 11.0 (Big Sur) and 12.0 (Monterey)

With Catalina, Apple dropped support for 32-bit applications, dropped the QuickTime framework that Igor used 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 or later to be fully supported on Catalina or later versions of macOS. However, Igor Pro 8.04 and later do run on these versions of macOS with the caveats explained here.

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