MacOS – How to get more information about Servers under Recent Items

Here's what happened. On the machines I was trying to reach (10.x.y.182 and 10.x.y.194), in the time when I was not using them they had their hard disks replaced and the OS reinstalled. This gave them new SSH keys, invalidating the ones I had in my ~/.ssh/known_hosts file. Unfortunately, Terminal.app did not surface this problem to me.

By deleting the entries for those machines in ~/.ssh/known_hosts, I forced the system to pull down the new keys and ask me if I wanted to use them. With this done, connections worked perfectly as usual. Oddly, however, even before I changed ~/.ssh/known_hosts, connections using the DNS name of the machine (svr10 and svr20) worked. Weird.

Thanks, everyone, who looked at this problem.

I don't know if this is really a "solution" per se, but it's a workaround that I prefer anyway: I changed the "Arrange by" to "None" as described here Mac OS X - File Open Dialog: Can't sort or resize columns

This gets rid of the categorization by Today/7 days/30 days/etc. altogether, and just gives a straightforward dialog that lets you sort however you want (be it Date Modified, or Name, or Size). I find this much more useful and fail to see the advantage of the other view (which is made almost useless by this No Date bug).

Note that some applications (e.g., MS Office) do not let you change the Auto-arrange setting. Just open up some other application that does (e.g., Chrome) and set it there (just go to Open File or similar -- you don't have to actually open the file). This action seems to set this setting globally (on 10.8.4).

This problem is all over the web. Why does Apple not comment on it? Does it not care about its users? Why does it not release a fix? Is iTunes so much more important? This bug seems almost ludicrous: The arrange-by setting used for categorization is (normally) "Date Modified", and the actual modified date is clearly shown in the Date Modified column. Indexing in the general case perhaps needs to happen not in real time (e.g., if you are viewing "All Files"), but when we open a dialog, can't just the (usually very few but most important) No Date files be manually indexed in that moment?
