Please read this whole message before doing anything.
This procedure is a diagnostic
test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in
safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including
sound output and
Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

That's it, worked for the same error here! Many thanks
It worked for me, too! Thanks!
That solution sounds like a work-around not a solution. You just made your system less secure.
If you find a better way, feel free to tell everyone.
not
Ace's! It worked right off the bat! Thank you very much, God bless you!
