更换白果之后，因为囊中羞涩买的是 32+256 的 macMini，所以需要把用户目录修改到外置硬盘里。但这样带来了个新问题，如题，下载 IDE 正常，但安装的时候报错“无法解压应用”，查阅日志如下：

解决方案如下：
mkdir -p /Users/Shared/JetBrainsCache // 在共享用户目录中创建缓存文件夹
rm -r ~/Library/Caches/JetBrains // 删除现有文件夹
ln -s /Users/Shared/JetBrainsCache ~/Library/Caches/JetBrains // 把 JetBrains Toolbox 的缓存目录链接到内置硬盘这样 JetBrains Toolbox 下载的 DMG 文件就在内置硬盘里了，就不会遇到上述问题了。
