I just got an M1 mac, and I ran into this same error.

I found that if I fully specify the pdflatex path, it works:

pandoc -o my.pdf --pdf-engine=/Library/TeX/texbin/pdflatex

It's a bit mysterious why this should be needed, since
`which pdflatex` returns this path!
And running pandoc with --verbose shows that the PATH is
correctly passed through to the process running pdflatex.

Anyone have any ideas? AT least this gives a workaround...
