对于M2

（1）下载作者开源的项目包，解压，修改hidpi.sh

修改前

function get_vidpid_applesilicon() {
…
# Get VIDs, PIDs, Prodnames

local vends=($(ioreg -arw0 -d1 -c $appleDisplClass | xpath -q -n -e "$vendIDQuery"))
local prods=($(ioreg -arw0 -d1 -c $appleDisplClass | xpath -q -n -e "$prodIDQuery"))

set -o noglob
IFS=$'\n' prodnames=($(ioreg -arw0 -d1 -c $appleDisplClass | xpath -q -n -e "$prodNameQuery"))
set +o noglob
