I am running Csound 6.15 and CsoundQt .981 and CsoundQt 1.0 beta on both a new M1 MacBook and on an older Intel MacBook and everything has been running running perfectly for the past few months.
Yes, there are crashes now and then, which are typically from CsoundQt, but that is also typical for my students running both versions of Qt on Mojave and Catalina and on my “teaching” Catalina MacBook.
And so… M1 Mac has been pretty fast and pretty great.
