"Unknown User" - How to Remove?

I just did a migration from my old macbook to my new one. Things got a little messy, and now I have a bunch of objects that are registered to user "Unknown".

If I create a new user on my computer, the objects get assigned to them.

What I would like, is to remove these owners from these objects (or at least give them "No Access") so that they can only be seen by my Admin account. I've got it set so that "Everyone Else" has no access, but these "Unknown" guys are bugging me. I might end up creating new accounts in the future and forget to deny them access.

(Please see the attachment for a visual.)

Thanks!

Yes I had the exact same problem

I spent a few hours trying to solve this issue. I ended up calling Apple care for help. The Apple tech almost instantly knew what I was talking about. He quickly walked me through a simple sudo command line for terminal.
The Problem was fixed and have had no problems since.

Sorry I don't remember what it was. But at least you know. That you probably will looking for a terminal command. For resolution to your problem.

The terminal command to change the ower & group =
sudo chown <user>:<group> filename <ENTER> (followed by your admin password)

Directories and files - changing owner

sudo chown -R <user>:<group> path<ENTER>

Once you press enter, you will be queried for your admin password.

This will sift through all the directories and files below the path and set the user and group of those objects as well.

Ok, so what should the syntax be to correct this problem?

need help with the command

I got the same problem though it's not on my main HD, it's on an external maxtor HD..

I'd like to try this command but I'm not sure what to put in instead of <group> and I'm not sure if I should use brackets for the (unknown) when replacing <user>..

I might be getting this all wrong too, I've never used the prompt on a mac before (I'm assuming it's just like unix)

thanks for your help!
