Try the Following:

• Create a New Administrator User:

See if you can perform this log in, using a new Administrator user. If it then works, then it is something misconfigured in your current user.

If that does not work...

• Try Booting into Safe Mode:

Hold Down: the shift key upon boot. While in Safe Mode, cashes are set aside, and login items do not run when logged in. So, see if you can log in using Safe Mode.

If that does not work...

• Reset the SMC and your NVRAM:

What it could be is settings. Sometimes when changes are made to the system(i.e. updates), system configurations (i.e. for Connections) become manipulated, technically. So, reset the SMC and NVRAM. You may need to perform this thrice. So, be certain you have the time to perform this.

Useless. I’d like to buy something. You would think they would fix this problem.
