Have only tested on one machine (MadMapper 3.7., but MadMapper seems to work well. Have tested multiple quads, video codecs. Only tested one output though.

Only issue seems to be the cue system / panel. it seems to function, but the GUI is unresponsive until you resize the window. At that point it will update values BUT you can't enter stuff in live or see the GUI's response in real time. Otherwise, works great.

Will keep ya posted on here.

I haven't tested BigSur yet.
As a general rule, it is better to wait a few months before switching to a new OS ...

Any news - does Madmapper support macOS Big Sur 11.1 ?

MadMapper is compatible with macOS Big Sur but was not yet optimized (you might encounter random minor bugs)
A version 4.0.5 will be available soon, it will fix the current bugs with macOS Big Sur and will be stable enough
