我有Mac 10.10.5， 我已经为Mac下载了Docker native。 尽管有管理员访问我的机器，我仍然收到以下错误
Administrator privileges are required.
You need administrator privileges on this computer to install Docker.
Please log in as an administrator to install the app, then you can use Docker
with standard user accounts.
我曾经拥有Docker Native Beta，几周后我尝试升级它，从那时起我开始遇到这个问题。 知道为什么会这样吗？
