Question

Our church has just changed to an iMac (From a MacBook Pro).  When I went to load up capture on the iMac this morning, the only available devices were "Built in Output" and "Fire studio". The 32.4.2 AI is not listed anywhere.  Therefore, I can only use the 2 default channelsThe board knows its connected, UC works fine but Studio one and capture don't see it.  I have tried a couple legacy versions of capture but still no go.

Any thoughts on this issue?

Please ensure that you have Universal Control correctly installed on the Mac.

Since the StudioLive mixers utilize a FireWire connection they also utilize the FireStudio drivers in regard to connecting to a computer. 
Even though the driver will show the StudioLive as a FireStudio you should still be able to utilize all of the inputs and outputs that are available for the mix.
