Has anyone ever encountered this problem when launching Blackmagic Media Express?
I find that launching FCPX and then quitting it usually gets Backmagic Media Express to see its own hardware. I have had this issue with the Intensity Shuttle Thunderbolt on my current Mac Pro (late 2013) as well as my Intensity Extreme PCie card in my old Mac Pro (2006 model).
Latest drivers? Yes, sure am. This has been an ongoing thing since I've had the Blackmagic product whether it be the Intensity PCIe card or the Thunderbolt Shuttle. Only Blackmagic's own Media Express app ever has problems seeing the hardware. Final Cut Pro X always sees it, never fails.
I didn't want to post this in the Final Cut Pro main forum because this is kind of different.
