sleep wake problem with Yosemite on my Mac Mini Mid 2012

I have a problem with Sleep Wake on a Mac Mid 2012 Mac Mini running 10.10, I was also a beta test user, and had seen the same problem before the official release. After the Mac Mini goes to sleep, and you try to wake it, it sits frozen, you can not enter your password, after about 5 minutes, the Mac reboots, and you can enter your password, the keyboard works again. I am using the Apple bluetooth MC184LL/A wireless keyboard. This same problem is occurring with the Logitech K760 bluetooth solar keyboard. I am now going to try only a standard USB keyboard, to see if the problem is somehow related to bluetooth? I been sending the reports to Apple about this problem since I started the beta testing from the start of the Yosemite beta test. It seems this is low on the list or is somehow related to my machine only? I have never had any problems with my Mac Mini, and have never done anything to the device (I never opened the Mac).

Any one else with the same problem? Thanks!

In the Windows/Bootcamp area, there are worse problems than just being unable to log-in. There is potential data loss.


PS: If Steve Jobs was running the company, this would not have see the light of day with a release.

Same issue - waiting for fix and to the comments above, ... Yes had to reinstall windows - again.... and I TOTALLY agree with the last statement... QA has not been as good of late.

For those who still suffer from this problem: eliminate one audio output to solve the issue.

You can do it either by not using the headphones plug and connect your speakers to the monitor (if your monitor has an audio out, mine does not), or eliminating a direct HDMI connection (as HDMI transfers video and audio). Mac Minis are shipped with a HDMI-to-DVI adapter, use that one with a DVI cable, or any other adapter, till Apple solves the issue.

We know they can, they did it already 🙂

Well... I use the adapter, and still have this issue... so now what? I'm guessing the audio is still being sent so it doesn't matter if you use it... its hosed, till the patch I guess...


Apple QA /= to what it used to be... slipping would be a good word to describe it.... hired too many google guys I guess.

Well, about that: OS X 10.6 and 10.7 in 2011 and '12 had similar issues, if not bigger, and Steve was there back then...

Besides, I had to play the same game when I installed a Windows on my girlfriend's notebook (last time I set up a Linux for her 🙂 ).


It is the short update times software companies try to dictate to impress users, who are lately got used to the quick update cycles on their smartphones/tablets.

First issue of an OS is still quasi beta, and we have to do the final testing. All OSes are like that, but only Linux admits it 🙂


If you want to avoid such pain, do not install .0 versions, wait for the .1, or rather the .2.

I always say that to myself, but never keep it 🙂

True statement, but... APPLE SAYS it works... so... shouldn't it <evil wide grin>. Apparently i'm into pain... as I KEEP getting and installing their latest stuff... cuz its usually rather good... ah well - a minor inconvenience at the moment - At least I'm not BSOD'ing like some "other" guys at launch.

In System Preferences / Sound / Output do you still see 2 outputs, or just one?

I have there only Headphones now, and all is fine.

Have you tried the obvious steps, like restart, repair permissions, or even delete settings files in Library?

Just one output - "headphones". I did a PRM reset - which hosed the account to the point I got a lot of other bugs. Created a new user account... fixed "some" of the newly created bugs from the PRM reset... Then gave up and reinstalled from a fresh drive (format/ Mtn Lion/Yosemite upgrade.)

Just to switch things up...I'm having the same problem on my 2010 Mac Pro using the front or rear headphone jack. No HDMI in the picture at all.


I noticed when I first installed Yosemite that my sound didn't work, I moved my headphone plug from the back of the machine to the front and it worked fine. Now I'm having the non-responsive sleep issue. I can move my mouse but nothing responds after waking from sleep.

I agree completely. I'm not going out to buy new monitor/audio cables, new monitors with earphone jacks, or anything of the sort that has been suggested in this discussion. It's great that people go through the effort of troubleshooting, and if they find a solution that's acceptable to them - good for them. However, in my opinion Apple created a problem and Apple needs to fix it.

I haven't seen this problem on my install, but the symptoms being described here are classic power management problems.


The usual first-aid for this kind of problem is to reset BOTH the NVRAM (PRAM) and the SMC. I've seen people in this thread mentioning they tried resetting NVRAM(PRAM), but I haven't seen anyone saying they tried resetting SMC. The instructions for both are linked in the quote below from Apple's official support documentation for this problem:



If the steps above do not resolve your sleep-related issue, try these additional recommendations.

Reset SMC

The System Management Controller (SMC) is involved in managing power on your computer. Reset the SMC on your Mac if you are having difficulty sleeping or waking your computer.

Reset NVRAM/PRAM

Nonvolatile RAM (NVRAM)/Parameter RAM (PRAM) stores some power-related settings.Try resetting NVRAM/PRAM if you are having difficulty sleeping or waking your computer.

Test with external devices disconnected

Some external devices can prevent your computer from sleeping. Try disconnecting items other than your Apple keyboard or mouse from the built-in USB, Thunderbolt and Firewire ports on your Mac. If this resolves the issue, try reconnecting your external devices one at a time until you find the device preventing sleep or wake. Check the documentation that came with the device, or contact the device manufacturer for more information.

Try Safe Mode

Check to see if the issue still occurs when the computer is started in Safe Mode. If this resolves the issue, it could be related to a third party software item such as:

Try another user account

Try creating another user account, or log in as guest. See if your computer sleeps and wakes properly from the additional user account. If it does, your issue may be related to one of the following:

You can disable login items from the Accounts pane of System Preferences. Try opening only one app at a time in the original user account to determine which app is preventing sleep. If you isolate the issue to a particular app or login item, check its documentation, or contact the developer of that software for more information.
