How to disable Guest User

I am having the same issue as you. Trying to work it out. If I find a solution I will post it.

Go to Apple Menu > System Preferences.

Click on Users & Groups.

Click on the lock on the bottom left corner of screen and enter your password to unlock.

Click on the Guest User Account to select it.

Uncheck Allow Guests to Log into the Computer.

Click on the lock to re-lock the preference.

Thanks for the response, but I wish it was that simple. I have already tried that multiple times. I read somewhere else it may be something with "find my mac" involving iCloud. I signed out and disabled find my mac and that has not worked either. I would think that it is just a plist item that is not getting modified correctly.

I have exactly the same problem. Disabling it through System Preferences has no effect, and neither does unchecking Find My Mac do anything.

This is annoying.

I'm having the same issue. I've tried Unchecking Allow Guests to log onto this computer and it still doesn't work

Same Issue here on my rMBP 15" late 2013.

On MBA 11" 2011 all is OK ... find my mac ON, guest OFF, filevault ON.

I'm not seeing the same symptoms.

Guest is off and I don't see it in the login screen or fast user switching list.

If I enable Guest, I do see it.

But I did do a clean install of El Capitan, not an upgrade......

ya i also did a clean install and did everything that's been mentioned but still not winning with it.

I have tried this and yet I am still greeted by the Guest user on my login screen. I have been digging around and it looks like the Guest account is tied to File Vault. Have a look at this blog post I found (https://derflounder.wordpress.com/2014/12/18/ten-things-you-might-not-know-about -filevault-2/) specifically section 2.

This was never an issue with Yosemite.

I do not know how it happened but today when I turned on the computer is missing the guest account

What worked for me was to do the following:

1. Perform a clean install of El Capitan. (Do not signing into iCloud or turn on Find my Mac)

2. Enable FileVault and do the drive encryption.

3. Log into the new clean system and enable Find my Mac. (Log into iCloud etc as required)

4. Restart the system and see the Guest account in the login. Log into the system with your account.

5. Go to the Users under System Settings and disable the Guest Account.

6. Restart the system.

You should now have Find my Mac enabled and the Guest account should not show at the login screen. This worked for me.

I had exactly the same issue after upgrading to 10.11.1 today and noticing this guest account appearing at login after enabling Find My Mac.

Yep this simple config worked fine for me. And I still have Find My Mac on.

10second fix folks

Also, I don't want to turn off Find My Mac for obvious reasons.

All I had to do was sign out of icloud. Once you've signed out of icloud, go back to users in your system preferences and unlock the lock at the bottom left (enter your password), click on guest user and untick the box that says "allow guests to log in to this computer". Now the guest user is gone. Now you can sign back in to icloud, but when you sign in, DONT select " find my Mac", that will re enable the guest user profile. It has to be done in this order to work. I tried a few variations and guest user kept popping back up.

Hope this gets to someone who is still struggling.

I have found a way. You will simply do the following:

System Preferences => Security and Privacy => Unlock the lock at the bottom left => Click on "Turn off FileVault"

It worked for me.

I hope this helps 🙂
