Audirvāna last version? and which macOS it can be used on?

Hope someone can help answer these two questions. I want to use the old software on old Mac that still has some life.

Audirvāna 2.0 last version? and which macOS it can be used on?

your license key can only be used in the Audirvana 3.5 version. What do you mean by Audirvāna 2.0?

Hi Antoine, I have old license for v2 under a different email. What is the last macOS version v2.6 is supported on? Thank you!

It should work on El Capitan but it may not work properly with Catalina or Big Sur since we do not support it anymore since 2017.
