Hi, I'm running High Sierra OS on a 2013 Macbook Pro 15" Retina.
I recently upgraded to High Sierra and CC 2017. Things worked fine for a while until I upgraded to the latest version of CC. Now when I try to go into Multicamera mode Premiere crashes. It does the same thing with other projects, so I know it's not just a glitch in my current project. But it seems to work fine on my desktop at home (which has the same OS and version of CC).
