The Mac port based on Emacs 27.2 is now available from

  ftp://ftp.math.s.chiba-u.ac.jp/emacs/emacs-27.2-mac-8.2.tar.gz

and Git repository is also available at

  https://bitbucket.org/mituharu/emacs-mac.git

If you build from the repository on M1 Mac with newer autoconf, then
you will need to do "git restore build-aux" after "./autogen.sh".

The configure option --with-mac-metal is disabled by default.
I originally turned it on because it lowered the CPU load.
But I recently realized that it was caused by its lower frame rate.
M1 Mac accomplishes 60fps with or without Metal even with large
frames, and the CPU load does not get an advantage from the use of
Metal there.
