OS Xの端末を介して、接続されているモニターとディスプレイ、およびそれらの解像度に関する情報を取得する方法はありますか?
複数のモニターで実行され、モニターが接続されていない場合はGFLWウィンドウが開かないように見えるインストールがいくつかあります-モニターが正しく接続されているかどうかを確認し、ログファイルにダンプしたいのですが、しかし、Obj-C/Cocoaに深く踏み込むことなくそれを行うためのプログラム的な方法を見つけていません。
system_profiler SPDisplaysDataType
またはdefaults read /Library/Preferences/com.Apple.windowserver.plist
を使用できます。
$ system_profiler SPDisplaysDataType
