Mac OS安装QEMU 运行ARM操作系统
废话不多说，直接上代码，可以拷贝黏贴，快速验证一下.

#如果要确保可以下载，提高速度，如果有代-理，可以类似这样操作，
#export http_proxy="http://127.0.0.1:8001"; export HTTP_PROXY="http://127.0.0.1:8001"; #export https_proxy="http://127.0.0.1:8001"; export HTTPS_PROXY="http://127.0.0.1:8001"

echo "在MacOS上使用QEMU模拟Raspbian（Buster)"
echo "安装QEMU:"
echo "brew install qemu"
echo "下载 qemu-rpi-kernel:"


wget https://raw.githubusercontent.com/dhruvvyas90/qemu-rpi-kernel/master/kernel-qemu-4.19.50-buster
echo "下载 versatile-pb.dtb:"
