I don't know what this refers to: M1 Mac CRAN checks are planned but 
AFAICS not yet included in the main results tables.

OTOH, 'Additional issues' on M1 Mac have been reported on the results 
pages since early December.

'requirement' for what?

I am not aware of any CRAN package for which 'R CMD build' does not work 
on an M1 Mac.

*Checking* might need an M1 Mac machine.  CRAN has only been notifying 
issues which can easily be corrected without access to M1 hardware (such 
as using suggested packages unconditionally or using optional 
capabilities without checking).

Please do re-read the posting guide (and 'Writing R Extensions').
Also, this is not r-package-devel ....
