我可以检测来宾是否正在使用OSX计算机？

Question

I am writing a tool that will expose an http interface on localhost. I'd like for it to not be available to a guest using the machine. I'd like to have the tool refuse connections entirely when a guest is logged in. Is this possible? Is there a way to detect this situation?

Answer 1

It turns out that guest accounts cannot run concurrently with normal accounts in OSX (at least on recent OSX) so the issue we were concerned about is a non-issue. You could theoretically detect it with w as Mark said in the comments, but it's a thing that won't happen.
