Due to various circumstances I never had the chance to do much with my original SL16.4.2. The opportunity to change that is now here and although I still have an older 2010 17" MBP with firewire I'm also hoping I can get this to work with one, or both, of my newer MBP's. One is a 2017 model still clinging to the last OS10 version and a newer one I bought earlier this year with OS11.6. I have the necessary adapters for the hardware but I'll bet there's things to do in the OS to allow the software to work.
