Hi,
My Audiobox USB 96 shows the current, and latest downloadable, version of firmware to be v1.12. There is no list of firmware that I have found on the Presonus website so I can't check whether this is correct or not. I have seen reference to later versions of firmware in the forum questions here, notably v1.14 as far back as 2018. It seems odd that I still have v1.12 and that is listed as the latest version. I'm concerned in particular as MacOS has a habit of stopping supporting items of hardware even if they are attached via a standard USB port and would like to ensure I am at the latest version.
Cheers,
Andy
