Apple Silicon Mac 获取显示器 Product ID 和 Vendor ID

在 Apple Silicon Mac 上对显示器配置进行修改时，往往需要用到 Product ID 和 Vendor ID 信息，使用下面的命令可以轻松获取到 ⚡

# 查看 CPU 信息
AS=$(sysctl -n machdep.cpu.brand_string|grep Apple|wc -l)
# 如果是 Apple Silicon Mac
if [ $AS = "1" ];then
	vids=$(printf "%x\n" $(ioreg -l|grep -i "DisplayAttributes"|grep -Eo "\"LegacyManufacturerID\"=\d*"|awk -F'=' '{print $NF}'))
	pids=$(printf "%x\n" $(ioreg -l|grep -i "DisplayAttributes"|grep -Eo "\"ProductID\"=\d*"|awk -F'=' '{print $NF}'))
	names=$(ioreg -l|grep -i "DisplayAttributes"|grep -Eo "\"ProductName\"=\"[^\"]*"|awk -F'="' '{print $NF}')
	num=$(echo $vids|awk '{print NF}')
else
	edids=$(ioreg -lw0|grep IODisplayEDID|grep -o "<.*>"|sed "s/[<>]//g")
	vids=$(printf "%x\n" $(ioreg -l | grep "DisplayVendorID"|awk '{print $NF}'))
	pids=$(printf "%x\n" $(ioreg -l | grep "DisplayProductID"|awk '{print $NF}'))
	num=$(echo $vids|awk '{print NF}')

for i in $(seq 1 $num);do
	vid=$(printf "$vids\n"|sed -n "${i}p")
	pid=$(printf "$pids\n"|sed -n "${i}p")
	if [ $AS == "1" ];then
		name=$(echo "$names"|sed -n ''$i'p')
	else
		name=$(printf "$edids\n"|sed -n "${i}p"|grep -Eo "fc00.*?0a"|sed "s/^fc00//g"|xxd -r -p)
done
