Detect Apple Silicon from command line

May 27, 2023 by Tarik

uname -m

will return arm64 as opposed to x86_64

if [[ $(uname -m) == 'arm64' ]]; then
  echo M1
fi

or, as @chepner suggested

uname -p

will return arm as opposed to i386

if [[ $(uname -p) == 'arm' ]]; then
  echo M1
fi

yet another tool is arch:

if [[ $(arch) == 'arm64' ]]; then
  echo M1
fi
