Slightly tangential: I had some woes with some vignettes in my
optimx and nlsr packages (actually in examples comparing to OTHER
packages) because the M? processors don't have 80 bit registers of
the old IEEE 754 arithmetic, so some existing "tolerances" are too
small when looking to see if is small enough to "converge", and one
gets "did not converge" type errors. There are workarounds,
but the discussion is beyond this post. However, worth awareness that
the code may be mostly correct except for appropriate tests of
smallness for these processors.

a) Use the 'mac builder' CRAN offers:
https://mac.r-project.org/macbuilder/submit.html
b) Use the newly added M1 runners at GitHub Actions,
https://github.blog/changelog/2024-01-30-github-actions-introducing-the-new-m1-macos-runner-available-to-open-source/
Option a) is pretty good as the machine is set up for CRAN and builds
fast. Option b) gives you more control should you need it.
