“操作无法完成。设备已分配，但卡在创建状态。” （外部设备上的 Xcode 13 iOS 模拟器）

Question

为了节省我的（M1，2020）MacBook Pro（MYD82LL/A）内部驱动器上宝贵的 256GB 磁盘空间，我在安装 Xcode 后在 macOS 终端中运行了以下命令，以移动所有空间 -将组件占用到我格式化时命名为“Developer”的 2TB 外部驱动器中：

\n

sudo mv /Applications/Xcode.app /Volumes/Developer/Applications/Xcode.app && sudo ln -s /Volumes/Developer/Applications/Xcode.app /Applications/Xcode.app\nsudo mv ~/Library/Developer/CoreSimulator /Volumes/Developer/CoreSimulator && ln -s /Volumes/Developer/CoreSimulator ~/Library/Developer/CoreSimulator && sudo chown -R $USER:staff /Volumes/Developer/CoreSimulator\n

\n

尽管绝对确保 CoreSimulator 文件夹具有正确的所有权和权限（因此sudo chown -R $USER:staff /Volumes/Developer/CoreSimulator如上所述），但我在尝试模拟设备时仍然收到此错误（图像缩小，因为 2880x1800 Retina 分辨率会推高屏幕截图的文件大小）过去 2MB）：

\n

\n

更奇怪的是，我在 Xcode 中尝试执行此操作，同时还在tail -f ~/Library/Logs/CoreSimulator/CoreSimulator.log单独的终端窗口中运行。鉴于我确信（通过chown）确保我已经对移动的目录具有写访问权，因此生成的实时日志信息似乎违背逻辑：

尽管已经使用过，但请注意各种“您无权保存文件”错误chown -R在目录移动后已经使用过尝试纠正可能由此产生的任何权限问题。那么这里还有什么可能是错误的呢？

我能够在这个答案的帮助下找到解决方法 /sf/answers/4081317831/

问题在于 CoreSimulatorService 需要完整的磁盘访问权限才能在单独的驱动器上创建文件。要授予访问权限，您需要拖放com.apple.CoreSimulator.CoreSimulatorService.xpc到系统偏好设置中的应用程序区域Security & Privacy > Privacy > Full Disk Access。您不能使用 + 图标，因为.xpc文件将呈灰色显示。

对我来说，这是 xpc 文件的路径： /Library/Developer/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc
