[Discussion] Trouble Downloading Spleeter

I am completely new to GitHub, as well as using stuff like Spleeter. I currently use a Mac with the most recent version (10.15.4) and I've been having trouble downloading Spleeter. Because I'm a noob when it comes to any sort of coding, I don't really know what I'm doing, and it is hard for me to find a good video on how to properly install and use Spleeter.
During the installation process, I run into a repeating issue. Command prompt says "Solving Environment," then soon after, "failed with initial frozen solve, Retrying with flexible solve."
Is this a problem with the OS I'm working on? I also didn't install FFmpeg. Is this needed to run Spleeter?

Any help would be much appreciated, especially since it seems not many use Spleeter on Mac OS.
Thanks!
