10.11 El Capitan中，需要拷貝override文件的地址變更為 /System/Library/Displays/Contents/Resources/Overrides 但是由於蘋果提升了系統安全性，用戶無法將文件拷貝入此文件夾（會出現禁止符號，沒有密碼提示）。 这是我之前的问题： 我的Mac由于工作需要，接入了一台超宽屏幕的外置显示器，分辨率是1560*1080.用的是Mini Display Port转Display Port接口，结果有一个问题。 什么都还好，就是字体十分发虚！网页上的字体还勉强，打开iwork编辑，字体只要小于12号根本没法看。 结果进入系统信息，发现这个显示器被mac识别为电视了！请看下图。 最后一项TV是yes。 请问如何让mac把它识别成显示器不是电视从而改善字体发虚的问题啊！网上的帖子都试过了无效，谢谢各路大神了！ 解决方法： 这是因为Mac在识别显示器上不够智能，经常把显示器识别为电视，所以导致采用电视的渲染方式，使得字体模糊发虚。 所以我们要对显示器强制RGB渲染。 0.下載這個到你的Downloads文件夾 patch-edid.rb (1.49 KB, 下载次数: 1898) 1，打开终端，输入 cd Downloads ruby patch-edid.rb （这是一个命令，不要拆成两行来输入） 2，打开“下载”目录，你会发现多了一个文件夹（以我的为例：DisplayVendorID-5e3）...
