I have Macbook Pro Retina, 15-inch, Mid 2014 (MacOS Sierra Version 10.12.6).

Since a week ago, whenever I wake up the laptop from a long sleep - its freezes:

  • The login screen is being displayed.
  • The cursor is inside the password field and it's blinking endlessly.
  • The laptop is not responding to the trackpad or any of the keyboard keys, except the power button which turns the screen off and on (when it's on again - it enters the same state).

The only thing I'm able to do is to long-press the power button until the OS restarts. The OS is responding normally after that boot, closing the lid and re-opening it after a short while - works normally.

What can I do to solve it so the laptop will wake out of sleep mode?

  • Have you looked at the System Log or any other logs for clues? Have you tried plugging in an external USB keyboard (or even a Bluetooth keyboard for that matter) to see if the problem is specific to the built-in keyboard/trackpad? – Spiff Jan 17 '18 at 22:54
  • I guess there is no problem with the built-in keyboard/mouse, because after the reboot they were working well. I did the steps listed here and it didn't happend so far: lifewire.com/how-to-reset-mac-pram-or-nvram-2260839. Thx for your response... – A-S Jan 19 '18 at 21:51

I've done the steps listed under the headline Resetting the Parameter RAM in the following article: https://www.lifewire.com/how-to-reset-mac-pram-or-nvram-2260839

And it didn't happen again so far...
