This is clearly for advanced users. I've just tried it and it'll probably be useful when diagnosing a faulty app, etc.

MacUpdate : " Sloth is an OS X application that displays a list of all open files and sockets in use by all running applications on your system. This makes it easy to see which apps are using which files and sockets. " What am i supposed to do with that information. I have macOS High Sierra ( 10.13.4 ) and Sloth 2.4 produced pages and pages of information which tells me that my system is using too much cpu or what ?

This app does not display any results on my system even after authenticating it. I run El Capitan 10.11.6. I tried several other versions, 1.6 and 1.7 and got the same results. Any ideas? I will rate it again once I get it to work.

It's a nice replacement for the now-retired WhatsOpen app. Would be nice if the app would be codesigned, so that I can tell others to use it without effort. Having to explain to them how to Launch this around GateKeeper is a pain.

I had some problems with the archive I downloaded for this app. First of all, BetterZip encountered an error and couldn't extract it. Second, ArchiveUtility was able to extract the archive, but the version of the app and folder extracted showed as 1.3.1. Strangely, the contents of the archive when displayed in BetterZip before extraction showed a folder numbered 1.4. I tried redownloading in case the file had become corrupt, but I had the same issue. Anyone have any suggestions?

as it says above, this is a frontend for the lsof command in the terminal. this same type of thing can be done just by piping 'grep' with 'lsof' in the terminal. like this lsof | grep iTunes if you wanted to do the same thing without the gui.

Very nifty utility! Though, sorting items by column doesn't seem to work.

What a handy little utility - thank-you! IMO, "Ferret" would have been a more appropriate name for it; though, of course, the icon... [Example: http://www.akanimalfood.com/ferret.jpg] ...wouldn't have been any prettier! *LOL*

Very nice, and useful. I just missed the hability to order the items clicking in the column title. A "search" function would be awesome! ;) Thanks for making it free for everyone.
