@TechnogeezerI think you've got it summarized right. I spent a bit of time with the Apple customer support crew this morning. Basically, we are stuck in the chasm between early adoption and full ecosystem penetration of the new architecture. Apple was very cool about my return (within the 14-day policy window). The rep also provided some temporary ideas to help bridge the gap. I will say that during the process of bricking the return laptop, the erasing and re-install of Big Sur went super, super fast. So, I can see where the M1, when everyone's on it, will be pretty awesome. Thanks again for your insights.
