Blackmagic Intensity Shuttle Usb 3.0 Driver Mac

Had an issue back in October where my MacBook wasn't even recognizing the BlackMagic Intensity Shuttle plugged in via Thunderbolt -- @Harold suggested updating the firmware/BM Desktop Video; this remedied the issue.
However, while OBS now recognizes something is plugged into the Thunderbolt port, no combination of resolution settings on my camera, the Blackmagic Desktop Video app and the OBS drop-down is displaying video. The only success I've had in the past with OBS was when my camera was set to 720p 30 but the 'mode' on OBS was set to 720p 59.94.
I've tried using Wirecast and a different camera -- still no luck, no video/audio signal from Thunderbolt. Theoretically, I would just set the camera to 1080i 60, the 'default video standard' on the BM Desktop Video app to 1080i 60 and then when I add 'Blackmagic Device' on OBS, I select 1080i 60 on the 'mode' drop down....and voila....but it never works this easy, ha.
What is it you think I'm doing wrong?
