Spencer,
as Duncan pointed out that is an issue on your machine, so only you can fix it. The checks use whatever you give them.
FWIW the macOS CRAN setup uses TeX Live 2019:
$ pdflatex --version | head -n1
pdfTeX 3.14159265-2.6-1.40.20 (TeX Live 2019)
You can upgrade your TeX installation if you so desire, the latest version for macOS is available from
https://tug.org/mactex/mactex-download.html
and other TeX mirrors.
Cheers,
Simon
