Sharing & Permissions - My User Name Does Not Appear

You mean here?

That is ABSOLUTELY NORMAL, and you should not try to change that.

These are the permissions for the drive, and not for your home folder, or files and folders therein.

It is perfectly normal for some files that you need to authenticate before deleting.

Now, if this is happening for files that are, for example, on your desktop or another of your own folders, that would be different.

You need to tell us exactly where those files you are deleting are.

Hi.

On my Mac HD my user name does not appear in the list (just system, wheel, everyone).

When I try to add myself I get a message 'The operation can't be completed because you don't have the necessary permission'.

My user account has the admin permission, but if I can't add the user how can I get the permission I require to make the changes?

The result is every time I try to delete a file I get asked to enter my password.

Se if there is anything here:

deleting files requires password
