I get the below error message when trying to install Audirvana on mt Mac. I am running macOAS Montery (tried on Big Sur as well) and i get the no mountable images message for the 1.8.5 installer and also the 3.5 one.
The installer downloads instantly and is only 20MB big. Is that the correct size ?
I did try to verify it with the diskimafge util and it says the image is ok .
Sounds like there might be something wrong with your macOS installation. I’ve downloaded the 3.5.50 installer which is 15,2 mb large. And it opens succesfully here. (2017 MacBook Air with macOS 12.0.1 Montery).
Haven’t tried AS, but that one always worked fine in the past as well. So I expect no problems there either
