Thanks, this is what is happening with almost any macos update since 2010 or so. Some problems were caused by the 64 bit switch, but also the system's firewire driver and api was changed by apple, so a lot of 64bit drivers also stopped to work. Usually Apple provides zero information about the changes, too. And does not annouce it either.
Sure I could now buy a RME device for about 800++ euro, but I also need two, so already 1600 eur, only to keep my macos audio system running.
Ok, I will stop now to rant about this, but I only wanted to add another perspective to the topic and why I think that waiting another year was not a bad idea for Bitwig either, or at least not prioritizing the ARM support...
