开启hidpi模式

sudo defaults write /Library/Preferences/com.apple.windowserver.plist DisplayResolutionEnabled -bool true

检测您的显示器

ioreg -lw0 | grep IODisplayPrefsKey

得到输出的结果

"IODisplayPrefsKey" = "ioservice:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/IGPU@2/AppleIntelFramebuffer@0/display0/AppleBacklightDisplay-610-a019"
"IODisplayPrefsKey" = "IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/IGPU@2/AppleIntelFramebuffer@2/display0/AppleDisplay-10ac-d06e"

生成文件

第二行的10ac 和 d06e为16进制的数值，对应文件名：
/System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-10ac/DisplayProductID-d06e

并转化成10进制数字填入下面xml中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>DisplayProductName</key>
  <string>DELL U2515H</string>
  <key>DisplayProductID</key>
  <integer>53358</integer>
  <key>DisplayVendorID</key>
  <integer>4268</integer>
  <key>scale-resolutions</key>
  <array>
    <data>AAAKAAAABaAAAAABACAAAA==</data& 大专栏  黑苹果gt;
    <data>AAAFAAAAAtAAAAABACAAAA==</data>
    <data>AAAPAAAACHAAAAABACAAAA==</data>
    <data>AAAHgAAABDgAAAABACAAAA==</data>
    <data>AAAMgAAABwgAAAABACAAAA==</data>
    <data>AAAGQAAAA4QAAAABACAAAA==</data>
    <data>AAAKAgAABaAAAAABACAAAA==</data>
    <data>AAAKrAAABgAAAAABACAAAA==</data>
    <data>AAAFVgAAAwAAAAABACAAAA==</data>
  </array>
</dict>
</plist>

然后把文件拷贝到该目录：

/System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-`10ac`/DisplayProductID-`d06e`

重新启动Mac

重启即可切换设置的分辨率，如果设置中没有找到对应的分辨率，可以使用工具RDM来切换
