We only support Linux and MacOS right now.

From the installation script:

get_architecture() {
    local _ostype _cputype _arch
    _ostype="$(uname -s)"
    _cputype="$(uname -m)"
    if [ "$_ostype" = Darwin ] && [ "$_cputype" = i386 ]; then
        # Darwin `uname -m` lies
        if sysctl hw.optional.x86_64 | grep -q ': 1'; then
            _cputype=x86_64
        fi
    fi
    case "$_ostype" in
        Linux)
            _ostype=linux
            ;;
        Darwin)
            _ostype=darwin
            ;;
        *)
            err "unrecognized OS type: $_ostype"
            ;;
