Error code

[nol2001]

I can't delete files and keep getting 'the operation can't be completed because an unexpected error occured' (error code: 100022)

I have looked around the internet but can't find a satisfactory answer.

Did you try a restart?

 

[nol2001]

Yes

 

[simsaladimbamba]

Where do you want to deleted those files from? Does it happen anywhere?

 

[nol2001]

It does happen everywhere.

 

[simsaladimbamba]

It does happen everywhere.

Does it also happen in another, even temporarily created, user account?

What Mac OS X version do you use?

 

[nol2001]

It is OS 10.7.5

When I try to create a new user account it won't let me unlock the padlock in system preferences.

Did you create an administrator account?

 

[nol2001]

I couldn't create a new account at all, including an new administrator account because it wouldn't let me unlock the padlock.

Go to disk utility, select "Macintosh HD" and hit "repair permissions."

 

[nol2001]

I tried repair permissions and it didn't help.

Who's computer is this?

 

[nol2001]

It's my computer. I will restate the problem:

That's just one symptom of the issue. The other, more disturbing one is that you can't change a System Preference while you're in what I presume is an administrator account.

There's not an easy fix for this. If it were me I'd try to enable root user via Terminal, then use the root user credentials to try to create another admin account. If that succeeds, I'd log into the new account and see how things are working.
