After updating to Sierra my wife's 2015 MBP stopped freezing but now my Mid-2012 MBP freezes! I knew about when I logged off and when I
rebooted so I looked at the console log. There were too many messages
to mention and most of them either I didn't understand or didn't have
any idea what to do about. For example:

Nov 23 11:19:56 robert-peirces-computer com.apple.xpc.launchd[1] (com.apple.VoiceOver.running): The HideUntilCheckIn property is an architectural performance issue. Please transition away from it.

OK, but how?

The following occurred between the time I logged off and tried to log
back on and had to reboot. I'm thinking the 11:22 message was the last
one before it froze. 11:32 may have been when I started trying to logon
and 11:40 seems to be when I rebooted.

Nov 23 11:22:49 robert-peirces-computer com.apple.xpc.launchd[1] (com.apple.security.idskeychainsyncingproxy[9540]): Service did not exit
5 seconds after SIGTERM. Sending SIGKILL.

You haven't described the nature of the freeze. When does it happen?
What are you doing with the computer at the time? Does the cursor move
when you move the mouse/trackpad? Etc.

It is the same problem as my wife's had. If you let the machine go to
sleep it may not wake up. Usually this happens if I log off for the
night. This morning I just left it for a couple of hours and when I
came back all I had was the screen saver. I couldn't even get the mouse
icon to wake up.

My wife's computer seemed to freeze every time you let it sleep under
10.11.6. Mine only does it sometimes. I have not kept track of what percentage of the time it freezes but it is less than 100%. Her's
always froze.

Did the screen saver continue animations after you tried to wake up the computer? Or did it stop and display something else? Or was the screen
static (frozen)?

I couldn't even get the mouse icon to wake up.

Are you trying to say that the cursor wouldn't move when you moved the
mouse?

Did you try pressing the space bar or another key on the keyboard?

Did the computer respond in *any* way to your efforts to wake it up?

There's got to be something in common between the two of them. Often
kernel panics are caused by misbehaving drivers. So perhaps they both
have the same third-party kernel extension installed, or perhaps both
are connected to the same make/model external USB device(s that are malfunctioning during sleep/wake events). If the kernel is panicking
there should be a corresponding panic log with details about the panic;
IIRC you posted one of them for the other machine...

The cursor didn't even appear. I pressed several different keys with no result. Eventually I had to power down and back up

I have some add-on stuff but her machine is about as clean as can be.
The only thing we have in commons is we both use the Microsoft Wireless
Mobile Mouse 3000, but disconnecting it doesn't seem to help. The
interesting thing is I had not problem with 10.11 and she die. Now she
has no problem with 10.12 but I do. However, it isn't every time for
me. I can't even tell in advance if it will freeze. Sometime it does
and sometimes it doesn't. When I looked at the console logs I saw
nothing that I cold identify as any kind of a panic.
