Where is the Unitor 2.5 driver?

I have an emagic amt8 and a brand new Mac mini that I am setting up from scratch rather than using Migration Assistant. I found an updated driver here: Unitor Family Driver v3 - Apple Support

The system requirements includes Unitor Family Driver 2.5 but that link is broken. MacUpdate and some other sites appear to have the v2.5 driver, but I would obviously prefer to get it from Apple.. How can I report a broken page link to Apple?

Cheers,
