State of play for standalone building?

[thatkeith]

I haven't built a standalone for anyone else to run for quite some time, entirely because the process had become rather convoluted over recent years and I didn't have the head space to go through it all. So...

What IS the current advice for building properly signed, shareable standalones – for macOS in particular, but separately also for Windows?

(Apologies if this isn't the best place to ask, and also if this info is listed somewhere here. The forum's search engine won't allow "standalone" as a search term. :-/ )
