Download old version of Audirvana ? Help

Is it possible to still get a copy of Audirvana 3+? I have a Mac mini that can not run an OS beyond OS X High Sierra. It’s a solid machine and I’d like to move from iTunes/ bit perfect/ remote to Audirvana / Bit perfect/ remote but I don’t believe I meet the new specs required to run the most recent version. Any help is appreciated as I’d like to become an Audirvana user. Thanks !

I’m on High Sierra too and running the last Audirvana version without any problem

Hello @surround, to use Audirvana 3.5 you need to have at least El Capitan, which version of MacOS do you have?
