Folders with red minus sign?

For all of my non-startup drives, I simply mark them all as permission free.

Right click on the external drive's icon and choose Get Info. At the bottom right of the panel that appears, click the lock icon and enter your admin password. Then turn on the check box for, Ignore ownership on this volume. Close the get info box.

You may need to restart the Mac, but everything on that volume will now be treated as belonging to no one, and you can do whatever you want with the contents.

Do I need a degree in computer science to open this folder? lol

No, I wrote the command so you can cut and paste.

I was Owner/Admin on the mac this came from and I am Owner/Admin on this computer.

That doesn’t necessarily mean what you think it does. Your identical usernames might have a different User ID (UID). The first user will be 501, and that number is incremented by 1 for each added user.

You can view the permissions on that folder by running this command and looking at the entry for that folder.

ls -l ~/Desktop

Fetching… means the user on the folder is not recognized as a user on the Mac.

You might have to change ownership using Terminal.

sudo chown `id -n` ~/Desktop/Documents\ (original)

You need to be an admin capable user to change it.

What happened after the first time you entered it. There is a caret there after the line. That looks like the final " didn't get placed.

The second one seems to indicate that isn't the name of the folder.

Try this, enter the following, leave a space, then drag the folder into the Terminal window.

sudo chown `id -un` 

Probably need to escape the ( and )

sudo chown `id -n` ~/Desktop/Documents\ \(original\)

or

sudo chown `id -n` "~/Desktop/Documents (original)"

sudo chown `id -un` "~/Desktop/Documents (original)"

Ah, you didn't mention it was a TM drive. Fooling around with anything on such a drive is a good way to screw it up.
