Post-Install and Sleep Optimization

To ensure stable S3 Sleep and prevent Bluetooth disconnection or instant wake issues, execute the following commands in Terminal:

sudo pmset -a hibernatemode 0
sudo pmset -a powernap 0
sudo pmset -a standby 0
sudo pmset -a autopoweroff 0
sudo pmset -a proximitywake 0
sudo pmset -a tcpkeepalive 0

Enable 16:9 HiDPI on External 2K Displays (Optional)

If using an external 2K display (such as Lenovo Q27q-20) via HDMI:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/xzhih/one-key-hidpi/master/hidpi.sh)"

Choose Option 2 (Enable HIDPI with EDID) -> Option 4 (2560x1440 Display), then select 1600x900 HiDPI in Display Settings.
