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

修改后

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"))

local vends=($(ioreg -l | grep "DisplayAttributes" | tail -n +2 | sed -n 's/.*"LegacyManufacturerID"=\([0-9]*\).*/\1/p'))
local prods=($(ioreg -l | grep "DisplayAttributes" | tail -n +2 | sed -n 's/.*"ProductID"=\([0-9]*\).*/\1/p'))

set -o noglob
# IFS=$'\n' prodnames=($(ioreg -arw0 -d1 -c $appleDisplClass | xpath -q -n -e "$prodNameQuery"))
IFS=$'\n' prodnames=($(ioreg -l | grep "DisplayAttributes" | tail -n +2 | sed -n 's/.*"ProductName"="\([^"]*\)".*/\1/p'))
set +o noglob

只需要修改三行代码即可
