Musescore 4 on macOS High Sierra

Congratulations on the release! It definitely looks awesome.

My question, I have seen that Muse Hub is not compatible with macOS High Sierra (10.13.6). I tried downloading only musescore installer but apparently it is not compatible with my version of macOS. What would be the planned minimum macOS version to run MS4 on?

I currently work in an old mac mini and also on a windows 10 surface pro, so I have found myself working in several files from any of those. I think musescore files are not backwards compatible right? So I could not be working in different versions in both computers.

Thanks a lot for your reply.
