 ## macOS开发环境
 https://ue5wiki.com/wiki/2329190d/
 
+运行生成解决方案.sh时会提示：
+>ERROR: Invalid SDK MacOSX.sdk, not found in /Library/Developer/CommandLineTools/Platforms/MacOSX.platform/Developer/SDKs
+
 确认安装Xcode之后执行
 ```bash
 sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms /Library/Developer/CommandLineTools/Platforms

+## 为 xcode 开启多线程编译
+AMD CPU信息查看APP：
+https://github.com/trulyspinach/SMCAMDProcessor/releases/tag/0.7.1
+
+首先看一下 Mac 的硬件配置：
+>sysctl machdep.cpu
+
+找到 `machdep.cpu.core_count` 字段，其中的数值就是 Mac 的核心数。然后可以给 xcode 开启多线程，数量数为核心数 *2，如我的是 8 核，就可以开启 16 线程：
+> defaults write com.apple.Xcode PBXNumberOfParallelBuildSubtasks 16
