How to disable Guest User

You don't need to disable find my mac just go to

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 and make sure all three options are unchecked if one is greyed out check guest mode and then uncheck all three

Click on the lock to re-lock the preference.

thanks this option worked for me.

Thank you, this worked for me, but I would really like to have my data encrypted for security reasons. Is Apple working on some type of patch that will fix this issue?

Here's what I'm observing:

1. When FileVault is on:
   1. I always see the Guest account on the pre-boot login screen regardless of the Find My Mac setting or if the Guest account is enabled/disabled. Even if I sign out of iCloud, I still see the Guest account on the pre-boot login screen (i.e. the login screen when my MacBook first boots).
   2. After logging out out of a non-Guest account (without restart) AND if the Guest account is disabled, the Guest account will not show on the login screen.
2. When FileVault is off:

   The Guest account only shows on the login screen if it is enabled (as expected).

So, it seems like to me that when FileVault is on, the pre-boot login screen ALWAYS enables the Guest account regardless if you have the Guest account enabled/disabled in Users & Groups pane. The Find My Mac setting has no consequence on my machine. I just wished Apple documented the expected behaviour better as I find it strange that I have to make Safari available to everyone if I want my drive encrypted. Weird.

OS X El Capitan (Version 10.11.4)

MacBook Pro (Retina, 13-inch, Early 2015)

Appreciate your answer but signing out of iCloud is not something I want to do as I can then no longer sync with other Apple devices. As other's have stated this is something Apple needs to work on.

Agree with you, this did not work for me either. This was a result of the latest update for IOS El Capitan 10.11.5. I have tried several of the responses and they don't work.

Hello everyone!

I have the same issue on my MacBook Pro Retina 15 (Late 2012, OS 10.11.5).

The only way to solve the problem for me was check & repair the permissions!

You can do that by terminal:

sudo /usr/libexec/repair_packages --verify --standard-pkgs /

sudo /usr/libexec/repair_packages --repair --standard-pkgs --volume /

😉

The most easy way disable the guest account on setting then create new account.. restart the mac then login man account remove the created account. works like a charm for me. 🙂

I had to create a new Admin account and then this worked. I think it was due to the 3 selections for the guess user the one about Parental Control was checked and grayed out so I could not delete the Guest User. Seems to be working now. thanks

I have the same problem, but it is happening yet!

I can't disable the guest user no way.

Please, I need help, it's really boring, it's should be easy and simple!
