it would obviously great to have something like Win-builder/R-hub for the architecture of the M1 macs. I had an issue with the RcppCWB package I maintain in January and I could not get hold of a M1 Mac mini quickly. So I resorted to hiring one with MacStadium (https://www.macstadium.com/). That worked nicely and I had a testing environment within a few hours. But it is an expensive solution (~ 100$ per month)!
In the meantime I got myself a Mac mini... Great machine, but obviously not everybody should not be forced to buy one. So it would be great to learn whether there are plans to offer testing environments for Apple M1.

If there was a response to the "how can I test it out" part of this
question then I missed it. Can anyone point to a Win-builder like site
for testing on M1mac, or to the M1mac results from testing packages
already on CRAN? They still do not seem to be on the CRAN daily site.
Even a link to the 'Additional issues' on M1 Mac on the results pages
would be helpful because it does not seem to be in an obvious place. I
am trying to respond to a demand to relax or remove some package testing
that fails because M1mac gives results outside my specified tolerances.
The tests in question (in package EvalEst) have been used since very
early R versions (0.16 circa 1995), and used on Splus prior to that.
There has been a need to adjust tolerances occasionally, but they have
been stable for a long time (more than 20 years I believe). Since these
tests date from a time when simple double precision was the norm, the
tolerances are already fairly relaxed so I hesitate to adjust them with
actually examining the results.
