Big Sur review: rebuilding my MacBook with new software

I take the plunge and reinstall Mac OS on day one of a new release. What could possibly go wrong?

After checking whether the two daily-drivers that I use were fully compatible with the new MacOS release of Big Sur, I followed some rather arcane instructions to produce a USB install key for Big Sur, wiped my hard drive, and started afresh. This machine dates from 2016, and I suspected that after four different versions of OSX it was time to have a clearout.
