Yosemite Login screen ignoring login after Screen Saver This is regarding a:
MacBook Pro (Retina, 15-inch, Late 2013)
2 GHz Intel Core i7
8 GB 1600 MHz DDR3

I have a managed, admin, remote account on the Mac.
This is the only account on the Mac.

The Screen Saver (Word of the Day) is set to come up after 30 mintues.
Energy Saver is set to turn off the display after 30 Minutes.

Security setting is: Require password 5 seconds after sleep or screen saver.

I return to the system after 5 seconds since the screen saver has started, but before 30 minutes...

Routinely there is a problem where the login screen (Just offering a PW, not a username) ignores the typed in password.

The password is entered, the return key is hit. The password bullets highlight and the system sits and gives no feedback as to the auth status.
The clock is still running, so the system isn't locked up.

If I sleep the device (Either by closing the MBP or by hitting the power key briefly) then when the login screen comes back up (after reawake) a new set of issues occur.


Now the password bullets simply clear whenever the return button is pressed.
The restart and change user buttons accept the click and highlight but do nothing. When released they unhighlight.


The only escape from this is a hard reset holding the power button for >5 seconds.

Open to any suggestions.
I would create a test account on the computer and test it as well. If the issue persist it is a system wide issue. I would reset the SMC on the computer, try to boot into Safe Mode and try there as well. If issue is still persistent reinstall the OS through the recovery partition (you will not lose any of your personal data just reinstalling the OS)
