> Mostly, it means apps will need to be re-compiled for the new CPU architecture. For a while now, apps uploaded to the Mac App store are uploaded in an intermediate representation, so the final compilation to the specific architecture happens on Apple's servers. This puts Apple in a place where they can launch a new computer with an ARM CPU, and (ideally) all apps on the Mac App Store will "just work"TM out of the box. And they can know whether that will be the case before the launch, maybe even reach out to developers to solve issues ahead of time.

That sounds like an absolute nightmare. Imagine having to track down a bug that only appears after your program has gone through cross compilation on Apple's servers.

You wouldn't, you'd compile it yourself at that point.
