When I boot the laptop from shutdown state (not resuming or awakening), it quickly goes to the login screen as normal but the mouse and keyboard seem unresponsive, but not completely:

Every like 5-7 seconds I'm able to enter a keystroke or move the mouse. Using those time windows I'm able to enter the password and successful login.

Once I login, the laptop works perfectly fine and stable.

This is the log I recorded today when it happened again: http://pastebin.com/zaDp9xg9

It happens every time I fully reboot or shutdown the laptop, don't have any problems with suspension and awakening.

If I reboot resetting the PRAM, the problem doesn't appear until the next shutdown reboot. So what I usually do is reset the PRAM every time I boot.

I reinstalled the OS from scratch and the issue is still there. I also use FileVault.

Have anybody experienced a similar issue? Do you see anything strange in the log?

Thanks

  • I experience the same problems on a Macbook Pro Retina 13" 2016, fully updated. Did you make any progress? I noticed that if you force restart (by pressing and holding the power button) at the unresponsive login screen then at the next boot mouse and keyboard work correctly. – Pincopallino May 29 '16 at 11:11

Took the laptop the the official service and it was a faulty I/O board. They changed it and now it's working fine. Notice that I didn't get a full motherboard replace, just something called "I/O Board".

I have the exact same issue happening right now. Thanks for the resetting PRAM suggestion! I would add the following as a comment, but not enough reputation yet.

If anyone else runs into this, here are the instructions for resetting PRAM - https://www.lifewire.com/how-to-reset-mac-pram-or-nvram-2260839.

On pre-late 2016 Macbook Pros:

  1. Shutdown the computer
  2. Turn the computer back on
  3. Immediately press and hold the following keys: cmd+option+P+R
  4. Continue holding those keys until you hear the second startup chime and then release the keys
  5. Computer should startup normally

On late 2016 Macbook Pros and later:

  1. Shutdown the computer
  2. Turn the computer back on
  3. Immediately press and hold the following keys: cmd+option+P+R for a minimum of 20 seconds (longer is fine)
  4. After 20 second release the keys and computer should start up normally

I had the same issue with macbook pro 2017 (touch bar). keyboard not working after restart and I'm stuck in login screen. I just noticed that it's related to an accesibility option "slow key", try type and hold the keys while typing like a long press.!! Then it works!

  • But it was faulty I/O problem – Sam May 16 '17 at 8:05

I was just having problems with logging into my MacBook Pro, the cursor was moving but the password field wasn’t showing and I couldn’t seem to select anything on the screen. The tab key didn’t work, but the arrow keys did! I just hit the down arrow and the password field appeared enabling me to enter my password....phew! Thought I would share in case it helps others....

I found that unplugging the keyboard from the USB port, and plugging it into a different USB port seemed to fix the issue for me!
