sleep wake problem with Yosemite on my Mac Mini Mid 2012

Follow Up, Take Two:

Objective Development put out a new nightly release (v3.5 r4226) of Little Snitch 3 that fixed the system freeze due to incoming SSH connections in Yosemite.

• OS X Yosemite changed how incoming ssh connections are handled. Incoming connections are no longer handled by sshd directly but instead by launchd. On OS X Yosemite, this version of Little Snitch automatically converts existing rules to ensure incoming SSH connections work as expected.

It works as described. Related system hangs have stopped.

HDMI audio + 3.5mm audio jack wake from sleep issue still present. Have the machine set to not sleep to avoid crashes.

Or just unplug the jack before you go to bed and let the computer sleep. Use the audio when necessary for now, use a different type of adapted, or usb audio. Not setting to sleep seems like a waste of power... But to each her own...

Hi,

Installed Yosemite Beta 10.10.1 and YYyyesssss .... wake up problem seems to be away!

BUT

* Still network problem (content not showing when clicking on a network folder ... in case my NAS is a sinology. But problem with all network). Finally I have to reboot if I want the content again. Finder seems stuck as I have to hard reboot

* It's a pity but my MBPro is still veeeerryyyy slooooowwww! Nearly impossible to use!!!!!! Pleaaassseeee Apple a fix!!!

On my Mac mini and my MBPro it's an update (yosemite 10.10 to 10.10.1) from a clean install

I must be honest that I'm so disappointed with all these problems.

For me "a Mac" is running flawlessly ... ok may be some minor bugs ... normal.

But with Yosemite it's worst than any bad windows version!!!

COME ON APPLE! What's happening!

Confirmed only 2 methods work with my Mac Mini (late 2012):

1) Tap the power button to wake or,

2) Unplug any audio connected to the Mac's headphone audio out.

At least the problem is narrowed down and we don't have to reboot every time!

Sadly neither of those approaches work for me, mid-2010 Mini with HDMI for both audio and video (3.5mm jack is empty) and wake button does nothing. Looking forward impatiently to 10.1.1, which I guess I'll clean reinstall since all these hard power cycle reboots have doubtlessly created more issues I'll never want to track down. 😟

Same issue here with a brand new Mac Mini setup as HTPC and pulling audio through minijack. I had been an early days mac fanboy since 1986. Switched to windows in the late 90s due to work requirements and had to make do with windows quirks for many years. Things have gotten much better with windows 7. Lately I was thinking about switching back to the Mac, especially seing that it could also run windows in parallel for essential PC software. Just purchased a Mac Mini to try the water. Yosemite does feel great and intutive but huhhh crash on every sleep wake cycle. Where has Steve Jobs' obsession with quality gone? What a pitiful effort from Apple. Big FAIL and I will be sticking to windows for another while. Feeling sad for beloved Apple brand.

Please read the forum. It is a minor bug that has Apple's attention. Trust me they are aware and are working on a fix. In the mean time you have several options: USB sound card for under $15, wait a few weeks and use the internal sound, unplug the sound when you're not using the mac, turn off sleep.

Again, you have options and Apple knows. Enjoy your new mac and understand it's 10.10.0. This is a brand new OS and this is always to be expected when having a major upgrade of any OS. Was Windows 7 retail release perfect? Windows 8? It took until Windows 8.1 for most bugs to be fixed. At least we only have a few weeks.

You are new to macs, they release these patches fairly quickly. iOS had a 8.0.x release within 3 weeks and 8.x within a month. 10.10.1 has been released to beta testers which usually means we should see it fairly soon. At the latest New Years. At the earliest... any day now!

Thanks jlopez. You are right. I was just so happy to try the Mac again after all those years in PC land that it felt like a big let down. But let's not blow the issue out of proportion and give Apple a chance to fix it.

How did you do that?

Here's another fix that confirms the 3.5mm jack is the culprit in at least most of the cases here. I wanted to keep using my speakers because the HDMI speakers in the monitor are not nearly as good as my Bose externals. The way I have my mini set up doesn't allow me to get at either the power button or the audio out jack easily. I bought a Logitech Bluetooth Audio Adapter and paired it with my mini. The 3.5mm jack is now plugged into the adapter not the mini. Sound is still great and there are no sleep wake issues at all. Added benefit is simultaneous pairing with iPad as well. I'm not plugging Logitech here, I'm sure there are other Bluetooth adapters to be had and this fix involved a cash outlay so not for everyone but it works. Cheers.

Verified after disconnecting audio in/out jacks my computer wakes up from sleep.

My situations is "solved". I have removed all connectors to the 3,5mm headphone inlet. No waking up problems for 2 weeks. Friday I forgot to disconnect the headphones and voila...FREEZE.....

Although I think Apple should solve this (I never had this problem before, with speaker-monitor (HDMI) and headphones permanently connected) with an update of Yosemite, for now this saves you a lot of trouble.

Hope this "band-aid" solution will help the most of you out.

I've been following this thread because I have this issue. Unplugging my speakers helped me, but I can't connect speakers to my monitor.

One day, I was connecting through bluetooth,. but I can't remember if I had problems. I'm too lazy to wake up the speakers and my computer.

Same issue on a mid-2014 Macbook Air.

I see the login screen but it doesn't actually log me in. Clicking doesn't seem to do anything.

Worse than that, I often have to switch the machine off several times before it wants to log in again.

I spent 45 minutes yesterday just trying to log in.

WORKAROUND FOUND!

I have a mid-2010 mini that is hooked up to a plasma display via HDMI and has had this black display after being unattended problem. I had had Energy Saver set to NEVER sleep and had the Computer Name screensaver. i also had the DISPLAY set to NEVER sleep.
But, when I hit the space bar to to wake from screensaver I had a black screen.
WORKAROUND THAT I FOUND was to schedule automated restart of the system, daily at 5:00 am. Since then I have been finding my desktop instead of a black screen! :-)
