Yeah, that fixed it. :)
Great, thanks for reporting it! \o/
Before reading your last email, I tried removing "DisableDebuggerAttachment 0". That actually made things worse. The connections weren't showing at all, even after waiting 5 minutes. It may be the same underlying issue that you just fixed, but thought I'd mention it. (I'd test it again, but that particular config option requires a hard restart of the Tor service, so I'm going to leave it alone for now).
Yup, that's expected. Generally Nyx no longer requires folks to set 'DisableDebuggerAttachment 0' *but* that requires /proc contents that aren't available on OSX or BSD.
... pity.
