実行手順

SIP無効化

⌘-R を押しながら起動して、リカバリモードのターミナルから

csrutil disable

Overrideファイル作成

通常起動した後、

sudo mount -uw /

で書き込めるように再マウント。

Sharp AQUOS LC-40U40は VendorID : 4d10 ProductID : 115a だから、

cd /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-4d10
sudo cp ~/Downloads/DisplayProductID-115a .

みたいにして入れてやる。（ここにoverrideする情報がplistで入っている。）
