Another culprit is USB devices that don’t play nice with macOS. For instance, I’ve got an old (OK, very old) Macally “imedia” USB keyboard. When it is attached to a laptop, that laptop won’t stay asleep. Every time it is put to sleep (whether via timeout, menu command or closing the lid) it will wake up a few seconds later. Mac Freezes after Waking up from Sleep in macOS Sierra And How to Fix 2017-06-27 Jane 2 Comments “After updating my MacBookPro to macOS Sierra, the display sometimes freezes in the lock screen, when waking up from sleep. When I woke up last night it was a little windy outside, so I decided to unplug my MacBook Pro because the power tends to flicker here. When I picked up the MacBook I noticed that it was very warm, even though the lid was closed and it was in sleep mode.

  1. POSSIBLE FIX - I had this issue too, 2012 MacBook Pro, it began when I installed Sierra Beta 4, and got really bad with Beta 5. I had to do a lot of force-shutdowns everytime the computer went to sleep, and then the Kernal Panics started. I would log in, and the whole system would just crash shortly after. Sometimes during login.
  2. If the SIL of a MacBook Air (Original, Late 2008, or Mid 2009) flashes five times when starting up or after waking from sleep, and the pattern repeats after a brief pause, the computer's battery may require service.

Unfortunately there are a couple of reasons this can happen, and each has its own solution.

  1. Already mentioned on this site is to reawaken your computer without the power cord plugged in.
  2. Also already mentioned is if you awaken your computer and you get a black screen, tap the powerbutton once (which brings up Shutdown dialog box, though you can't see it) and then press the 'S' key, which will sleep the compuer and try reawakening. This frequently solves the problem.
  3. Lastly, if you have slept your newer-Powerbook or Macbook (standard or Pro) and while it was writing the contents of the memory to disk (ala Safe Sleep) unplugged firewire or USB devices you may have corrupted a preferences file. My guess is it is the Energy Saver or Display .plist file, but I don't know for sure.

When I had the black screen on my MacBook and solutions 1 and 2 weren't working anymore, I didn't have time to troubleshoot and locate the exact corrupt .plist. I didn't narrow the problem down to either a. Hardware problem or b. .plist problem so I did an archive and install to determine a or b and the problem has vanished. So I am guessing it was b. but that is a very good guess.

As for the corruption happening when unplugging USB or Firewire devices while safe sleep is writing contents of memory to disk, that is science but anecdotal. I noticed that when I did this (by accident – I thought the computer was all the way asleep) I started having the black screen problems that weren't solved by solutions 1 or 2 above. Thus my reasoning that the unplugging caused the .plist corruption, but I don't know that for sure.

Anyway, if it happens again, I'll figure out the exact .plist and submit a hint to this site, but until then, I think this comment will help those who have the black screen which isn't solved by 1 or 2.
