I have no access to a newer arm64 M1 machine. We have no immediate plans to update to newer Qt versions than the 5.12.x builds we use now as it would require us to drop support for macOS 10.12 (for Qt 5.15.x) and even 10.13 for Qt 6.x builds.

If you know of patches to get Qt 5.15 and QtWebEngine from 5.15 to build and actually work on M1 machines, that would be helpful! Python 3.9.x and Python 3.10 should already build on M1. I think pcre2 supports arm64 as well. Libffi and a few others may still need work but hopefully not.

I just hate leaving older versions of macOS behind just to constantly upgrade Qt. As far as I know, Sigil 1.8 should run just fine under Rosetta 2. That is our first priority. If you can test and confirm that, it would be helpful.
