I am having similar problems. The Ultrastudio mini recorder is downloaded and works(lights up, is recognized by Security preferences); however the computer will NOT recognize the camera. The Updated file from blackmagic is not event downloaded on the Security preferences page on my Mac. I have updated the Mac, the BMStudio 4k camera, uninstalled the software, reinstalled, restart, etc, etc. The computer allows the BM camera software to download and come up in applications but when I click start, the BM window pops up and it says, " No camera or accessory found" "plug camera in a USB port." My camera is plugged via SDI into the minirecorder and it is plugged via thunderbolt into the Mac thunderbolt port. HELP!! I have no hair left. I have no bullets left. Next, I will have no MAC and No black magic camera.
Thanks,
James
