Q: User not listed

In your other topic, you never said if your current user account was an admin one or not. That's the first thing to check -- sudo only works for admin users, as was explained in that topic.

There must be at least one admin user account. If you can't find one, something is seriously wrong with your system & that must be corrected before doing anything else, so please let us know if that is your situation.

Otherwise, in Finder navigate to the Users folder of the startup drive (one way is to type command + shift + g, enter "/Users/" without the quotes, & click the "Go" button) & note the names of the folders in it.

You should have a "Shared" folder & one for each user account on the system. How many folders do you see there?

I am having this issue too, I can only see "shared" in the users folder. It isn't backing my desktop up in Time Machine.

It has been there previously.

Hi Bill,

Not particularly helpful, sorry

OK, hope more help is on the way.

Would appreciate it, have just downgraded to 10.7.5. Ran Snow Leopard on older iMac and NO issues at all EVER.

Old system connected to ALL PC's & Macs, had no permission issues at all. This one is s dog so far!!

OK, I googled and found this command

defaults write com.apple.finder AppleShowAllFiles YES

killall Finder

I could then see my username, faded out but accessible.

Good work.

Why is it hidden?

Possibly this?

How to hide a user account in OS X - Apple Support

sudo dscl . create /Users/hiddenuser IsHidden 0

Made no difference.

Interesting for the Additional Options, my reading of it is that would HIDE the user. Plus I am OSX10.7.5 Lion

Ah, Lion, does this help?

This is the issue I have, I have blurred out some info, my account is not in the "Users" folder, but it used to be.

Have you gone into your Time Machine backup to see if the user is backed up at all?
