macOS下多用户远程RStudio Server绘图故障排查与解决

问题背景 #

我在iMac上部署了支持多用户和远程登录的RStudio Server，按照官方INSTALL教程完成了源码编译、配置文件设置和launchd守护进程部署。初始运行正常，但一段时间后绘图时出现报错，无法继续绘图，只能重启R再重新运行代码。由于macOS并非官方支持系统，提交Issue后未得到帮助；尝试用Docker运行也没找到合适的macOS用户命名空间映射方法。

解决办法 #

执行以下命令启动fontd守护进程后，问题已解决：

sudo launchctl load -w /System/Library/LaunchAgents/com.apple.fontd.useragent.plist
