Q: sleep wake problem with Yosemite on my Mac Mini Mid 2012

I have a late 2012 Mac Mini i5 and the latest update corrected the sleep wake up concern. After performing the update and repairing permissions I plugged my mini audio in/out jacks in and set to sleep in system preferences. Since then my computer has gone to sleep several times and have no issues waking.  FYI

My late 2012 Mac Mini, as explained three posts before this, still has the problem it had before updating to 10.10.1. I have it set to go to sleep if inactive for 10 minutes, and there is no problem waking up by simply pressing any key on the keyboard or clicking on the mouse within 2 or so hours of doing so, or as long as I can still see the light come and go. But when the light totally shuts off (I don't know how long it has to be before it does) that's when I have to lightly press the power button to bring it back. It didn't have this issue with Mavericks.

I have exactly the same problem. Cannot type password after Waking up from Sleep. Only way out is forced reboot. After that the unit starts in Safe mode ( bar scrolling at the bottom of Apple logo).

Will phone Apple tonight and if they solve it I'll list the fix here.

Will follow this thread in the hope someone gets there faster...

What a c..k up by Apple !..Samsung must be really happy reading this..

Update 21st October : : temporary fix seen in other forums : try to awake computer from Sleep using a brief touch on the power button, ie NOT by moving the mouse or touching the keyboard. Worked for me after full night on Sleep..

Two things here : looks like the problem is not computer Sleep but Screen Sleep, so not much gain from setting computer to Never Sleep as the screen will lock anyway after the set time ..

The last two updates ( camera RAW and Yosemite ) have fixed it for me. I suspect the camera driver clashed with the audio driver.

End of problem here.

I do agree there's still something funny going with display detection. I can sometimes see one or both screens flicker a signal briefly (wake from black, background for a sec, black for two secs, background + login) during wake from sleep.

For instance this morning, after tapping the keyboard, both my displays remained back for a solid 15 secs, then the big one displayed the fuzzy graphic of yosemite's default wallpaper, while the second display remained black. Additionally the language selector was missing from the upper right corner.

Now, I have not used that default yosemite wallpaper since the first day I had yosemite beta 1. Why would that suddenly pop up this morning?

The good news is that for the majority of people the external speaker thing seems to have been fixed; since 10.10.1 beta or release; but clearly there is still something lingering as evidenced by some of the last posts. Really puzzling.

I'Ve had this issue since the Yosemite upgrade.  (Mini won't wake from sleep and falls off network.). I run the mini headless as a Media Server.  Upon installing and testing 10.1.1 I can report the issue is NOT resolved.  The only workaround I've found is to set Energy Saver to never sleep.

Yosemite 10.10.1 update fixed it for me. Got a little faith back in Apple!

After today re-update to Yosemite 10.10.1 sleep/wake problem on my Mac mini Mid 2012 is send back into the cold, fully and properly :-)
I will not torment support…

Updated the mac mini yesterday but still can't wake up the mac after it goes sleep other than holding the power button for couple of seconds to turn off and then one second to turn on...losing hope (latest 2014 mac mini model)

After applying 10.10.1, my Mac Mini still cannot be waken up. My connections are pretty simple: a Logitech Unifying to keyboard and mouse and HDMI to Sony's TV. I checked the error log and before Mac Mini stops to work, these are always the last couple of exceptions from system:

acvpnagent: A network interface has gone down

acvpnagent: ...

acvpnagent: ...

discoveryd: Basic DNSResolver UDNS Send():

discoveryd: ...

kernel: AppleThunderboltNHIType2 ...

I tried to contact Apple to provide this information but the waiting line seems to be long...

Just wanted to add to the discussion. I am running an early 2010 MacBook Pro with Yosemite and am having the same Sleep Wake problem. At least that's what I think it is. it never seems to generate a crash report. I have an external monitor (Samsung) and an external drive (Seagate). Also an A1016 wireless keyboard and a Wacom tablet. I have upgraded to 10.10.1 and no change.

I had a white screen when the computer awoke after sleep. I could blindly type my password in and it would log me in.
I reset the energy saver settings to default and then back to where I wanted them and it cleared it!..

On an Mid 2011 IMAC running OS X Yosemite 10.10.1 same issue I had high hopes Apple would have addressed it with the 10.10.1 release.  Heartbroken again.

I experienced a similar behavior. Problem solved by disabling password login at wake up (System Preferences/Security & Privacy/General).

Apparently the issue in my case did not have to do with wake up, but with login right after wake up. Solved, but it is a bit annoying to leave my laptop without password protection.
