MacBook Pro (2016 touch ID) screen lock issue

For sure! Have you or anyone contacted Apple support about this? When I contacted them a couple weeks ago, they claimed they weren't aware of this issue. They suggested I first try using my laptop without my 5K LG display, which seems to prevent the screen turning off issue, but not the other issues. They also suggested creating a new user profile and see if that has any affect. Their final recommendation was to reinstall High Sierra without importing any user data.

In any case, there is definitely a bug, since this is undesirable behavior occurring to all of us. So it may be worthwhile for everyone in this thread and here to use what's left of our tech support and raise the issue with Apple, citing these two threads.

I can confirm I'm experiencing what sounds like the same problem. Screen can randomly lock if I stop using the machine for even a few moments. If I catch it quickly enough pressing a key or moving the mouse can cancel it but it's ridiculously annoying.

This issue also only started after High Sierra. I'm using a MacBook Pro14,3 (15-inch 2017).

Having the same issue like this:

By using shortcut (ctrl + cmd + q) or the control strip from touch bar to trigger screen lock. By right screen will black out, however now the it will black out first and light up right away to stay in login screen.

I think you are confusing display sleep with lock screen.

They are two DIFFERENT things.

Lock screen is what you are seeing. You need to enter your password to proceed.

Display sleep blacks out the screen (it may or may not be locked at this point, depending on your security settings)

You can black out the screen when it is locked, by pressing the ESCAPE key, or by using a hot corner.

Yes, there are two separate issues, as he described in his post.

I've noticed that situation where when you press the "lock screen" button it flashes black, then goes to locked account screen before finally sleeping the screen, weird but not an issue.

**Edit: To clarify on the above, this behaviour is NOT how it used to act in Sierra, El Capitan, etc. Before when you used the hotkey to LOCK SCREEN, it went instantly black (and locked account), it didn't flash about between black, locked screen on, then black again.

The real problem is the one where, while working (if not pressing keys for a few seconds or such) the screen randomly goes black and then if you don't react quickly enough, locks the machine, while you're working on it! This is not anywhere near in line with my energy saver settings (set to only automatically turn off display after 15 minutes, not 15 seconds).

This is most definitely a OS bug/issue which has arisen since High Sierra.

I have this problem too. My mid-2015 15" MacBook Pro Retina has started doing this, only after I updated to High Sierra. It darkens the screen and locks it, without any input, not even touching the track pad. You have to log in again and everything is there. Not easy to use this way. Imagine listening to music or watching a movie, and the screen locks all on its own.

I agree, it sure looks like a bug.

I have the exact same issues. The update hasn't resolved them. Do you guys also find that resting your finger on Touch ID unlocks the computer but doesn't turn the display(s) on? You have to click on the touchpad or press a key, and hope you don't mess up an active document. I've simply been pressing the touch ID button now, whereas before I could just rest my finger briefly on it.

Good news! I just updated (it wasn't showing available in my App Store for some reason). I'll update here if it stops happening, been super frustrating so far!

Yep, exactly same for me, update didn't fix it and yeah have to press the touch ID. It's so dumb and annoying...

Unfortunately 10.13.1 appears to be even worse than 10.13.0. Hopefully they release 10.13.2 soon as apparently it fixes it there... Cannot believe this passed QA...
