I would love if it can run on macOS 10.12 (Sierra)
The splitcam works like charm in PC Windows 10, however there is a delay (frame drops) in video sharing.
Transition effect sometimes buffers with text layers even if its at lower order.
SplitCam support only Mojave and higher, sorry about that.
What version of SplitCam you use ? And what your processor and video card?
If your PC not so powerful it's can drop frames !
