Firewire Audio issue with Focusrite Saffire pro 24 and mid 2011 iMac

Hi there,

As stated above, I'm having a sync issue.. System Profiler Can see the Saffire PRO 24, but the FW light isn't coming up...

Its the exact same scenario as whats going on in this post:

Re: Firewire Audio Issues

But the difference is, I'm running a 2011 iMac with OS X Sierra 10.12.6..

I did try to the provided link in that post to download the v2.2 Mix Control app, but there wasn't one available, there was only 1.8, 2.4, 3.2 +..

I have tried installing 1.8, just so it can "update" itself to whatever it needs, but it just says "No Hardware Connected"...

Any replies or direction will be much appreciated

Thanks.
