Guest User

Hi,

Go to System Preferences > Users and Groups

Unlock the padlock

Select the Guest User account.

In the right hand pane you can now turn it Off.

It is very difficult to manage without iCloud now.

Again in System Preferences > iCloud you can Sign Out or disable the services you don't want.

It should be noted that some Apps require that an Apple ID is iCloud valid but they are not in the iCloud settings.

These include:-

FaceTime and the iMessages account in Messages.

App Store, iBooks and iTunes. I link these together as they can access the same pot of money.

If settings in system preferences > date and time are unchecked , read and write permissions in guest user account , shared , home folder issues will come up in icloud keychain and may in login keychain , App Store , iTunes , in cloud website .

Various methods are there to rectify keychain .

If the Mac user has iCloud verification code in his records its easy to set up iCloud Keychain .

some articles are there OS X El Capitan: Set the date and time on your Mac

If you enter your iCloud Security Code incorrectly too many times - Apple Support

Another method is entering in recovery mode .

Change admin password in Mac OS Sierra

Close all applications and shut down the computer , press command , R and power key simultaneously , release only power key and keep on holding command and R key until apple logo appears , the bar starts loading let it be completed .

Select the language as English , go to utilities on top menu bar > Utilities > Terminal execute a command resetpassword and click on enter key .

Window appears , select your admin name it will prompt to enter Apple ID and password .once you enter the credentials , two options will be shown ( a ) previous ( b ) next , click on next .

Some fields will appear .

New password ……….

Verify password ……….

Password hint ……….

Enter your new password in two empty fields and keep password hint as empty ( optional ) .

It will again prompt two options ( a ) previous ( b ) next

Click on next .

Then it will prompt to restart the computer , so after restarting the machine .

The system was unable to unlock your login keychain , if you remember your old password you can update the keychain password .

If you do not remember your old password , you can create a new login keychain or choose to leave the login keychain using a different password .

Would you like to update the password , create a new keychain , or continue the login ?

A window will appear on your desktop .

( a ) continue login .

( b) create new keychain .

( c ) update keychain password .

Click on update keychain password , then log out from your computer .

When you again login in the fields enter your “ admin name “ and “ old admin password “ , so that new password will be updated with login keychain .

Hence , you have changed the admin password with the help of recovery mode only .

If keychain is corrupted , click on create new keychain , its a lengthy and complicated procedure , but every time iCloud verification is very much required .

See the steps , you must consult in apple support also .

Also , in Mac OS High Sierra , if keychain access is opened via spotlight , its preferences is opened .

Clicking on reset my default keychain can be done .

All the passwords will be emptied and you have to set up login keychain and iCloud Keychain once again ( make sure you must all of your passwords for webmail account , iCloud , Apple ID , if your are using airport express its base station or wireless network password generally both are kept as same ) before clicking on it .

Again stressing on iCloud verification code it has major role everywhere it can really help to configure .

I'd also like to point out exactly what the Guest account is. It is an account you can let someone use if they need to use your computer. It protects both your privacy and theirs. They can't access your information and, when they log out, all their history is deleted. If you ever let anyone else use your computer on an occasional basis, it's a great tool.

Same deal here except every time I power off/on, macOS re-enables the Guest account. I go and disable it, but it is back there upon reboot. Also, it lists the users instead of displaying the username and password dialog, which is what I would like. macOS gets worse every year.

Hi,

I can confirm that the Guest account is re-enabled when I check.

I had turned it off when I read this thread.

For a long time I have had my computer open automatically to the Account I use.

I will test this as well in High Sierra.
