sleep wake problem with Yosemite on my Mac Mini Mid 2012

The 10.10.1 update solved this issue for me! 🙂

About the OS X Yosemite v10.10.1 Update - Apple Support (information)

OS X Yosemite 10.10.1 Update (download)

Mac Mini (mid-2010) with HDMI video and audio, nothing attached to optical/analog output...was consistently locking up whenever my TV or receiver were turned off. Now it works great! Good luck everyone.

Fantastic that 10.10.1 sorted out your wake /sleep problem...

it's so frustratingly annoying.

Unfortunately, it didn't for me!

And, I still have the sleep/wake problem which

means i have to power down and power up the Mac Mini every time!

Which can't be good for the hard drive etc,.

Tried every conceivable workaround and fix...posted on here.

Did you do a "clean install" of Yosemite to begin with, and then

apply the update to 10.10.1?

Think I have solved this frustrating sleep / wake problem on Yosemite.

Tried every conceivable solution on this discussion site,to no avail!

1 Download, but don't install a fresh copy of Yosemite from the App Store.

It will take time (it's abut 5.7 Gb) and will be found in your Applications folder

just DON'T install it.

2 Download a application called Diskmaker X ( You don't have to go through Disk Utility

to create the bootable drive) and unpack it, keep it ready for step 4 You can get it here

http://diskmakerx.com/whats-this/

3 Using a spare USB device or portable ext hard drive (at least 8 to 10Gb storage size)

make a "Bootable Drive" (Mac OS Extended Journaled) from your downloaded OS X

Yosemite using Step 1,2 and finally,4.

4 When opening Diskmaker X it will ask for a USB deice to be installed on - have your

USB device ready to install Diskmaker X unto it. - This is your NEW Bootable device.

Just follow the notices.

5 Finally, with this new Os X 10.10.1 Bootable Drive software ensconced on your USB

storage device, restart your Mac holding down the OPTION key. Choose your new

Boot Drive and then do a Disk Utility full repair permissions verify and repair et al,

on your Mac.

This worked for me;as I've finally cured this most infuriating of problems.

I hope it works for you also.😉

Good Luck, and take your time. No need to rush it,

Please, let me know how you got on,or if you need further details, and/or assistance.

P.s

(This new Bootable Drive might also come in handy of and further problems that might arise.)

Hopefully you won't have to use it ever again...Good Luck!🙂

@C.J: your workaround looks like coincidence to me.

I will try it, but don't believe is going tot solve anything as i read this:

"Should I start up from a Mac OS X install disc to repair disk permissions?

This is not necessary because Disk Utility looks at the receipts on the volume being checked."

source: About Disk Utility's Repair Disk Permissions feature - Apple Support

Ok, Yosemite is not mentioned in that article. But....

@CJ

There is no need to download Yosemite installer especially since the file is over 5GB on the slow network it will take a good couple of hours. The same result you will get if you will boot your mac into Recovery Mode (reboot mac and hold CMD+R) and then you can repair disk permission on your Macintosh HD partition (or whatever is called if you have rename it) as you have done it.

Alternatively, you can use USB Recovery Asistant app (it will work with Yosemite too - test it already) to create bootable USB stick and perform the same steps as described above.

I have the Same problem in my Mac book pro - After upgrade to 10.10.1 !!!

Hopping this will get fixed soon or later in next fixes.

Waking up from sleep with power button works too with a mac mini late 2009 if you have some graphics issues. Thank you.

Third post here on my ongoing late 2012 Mac Mini wakeup issue (goes into deep sleep after a certain number of hours in sleep mode, and the only way to bring it back is by lightly pressing the power button) after installing Yosemite, which update 10.10.1 did not fix. Here is an interesting find: while the problem seems to be related to Bluetooth or HDMI connectivity for some people, mine appears to be related to USB connectivity. I connected my USB 3.0 third party external DVD drive, and after 10 hours of sleep yesterday and all night last night, the issue is gone. I'm sure that if I disconnect the DVD drive, the problem will reappear.

I will be performing a clean Yosemite install today to see if the problem goes away once and for all.

Hi,

I have this issue to on my iMac from mid. 2007 with Yosemite 10.10.1. The only connected device is a second screen from LG. It's connected over the Mini DVI output on the iMac and it's not a solution for me to disconnect it every time (and I didn't test it if this will solve the problem). There is no external sound device connected.

So I hope they will fix it soon, because this bug makes me absolutely crazy. And I didn't think that this will be good for the mac / HD to make a cold shutdown every time.

Here my bizarre story...

Also have the problem of not waking up in Yosemite 10.10.1 and also when running the Windows 7 partition on the Mac mini.

I just bought an Mac Mini 2012 model for my living room. Cause it is super quiet, no noise !

I did upgrade to Yosemite 10.10.1 and I also made a Windows 7 64 bits partition with Bootcamp. I use the mini with Windows 7 90% of the time and use Pulseway app for iPad to wake the mini from far away in the house or via Internet and access it with the great app on my iPad Air 2 "Splashtop-2".

With Pulseway app I can put to sleep and wake all my Windows-7 PC computer except the mini... In fact I can put it to sleep but cannot wake it up...

The funny thing is if I boot the mini in Yosemite and put it to sleep. I can use the Pulseway app whom is set to wake the Windows-7 Partition not the Yosemite one and it wake the mini Yosemite... ?!?!?!?

Maybe be it will help computer savvy people see some light about this bug...

In the end I found a little solution that is far from perfect but it can wake the mini running Windows-7 when I'm out and want to access the mini with splashtop via Internet. I created a task in Windows 7 to wake the mini every day at noon. I know it's not perfect but it work until Apple get it fix. I don't know if an equivalent task solution is possible in Yosemite. In fact I'm a power user on Windows system, but Im a complete newby in Mac Os system...

Yup, same situation. I have a mac mini (Mid 2011). It freezes up. I haven't added any software. I use it as a server. HDD capacity is 500GB of which 213GB are free. Space is not an issue. Removing the speaker jack is not going to do it.

Obviously Apple missed something in its Yosemite update.

They need to solve this issue ASAP. I am extremely frustrated and upset.

My 2014 MacBook Pro has these same problems. Total blackout of the laptop screen on sleep. I have to turn off computer sleep completely since updating to the lasted Yosemite version. This is with 10.10.1. I have no audio devices plugged into the computer, just the internal speakers. This problem is fairly recent. I suspect whatever the 10.10.1 upgrade fixed for the Mac Mini it broke for the laptop.

It sounds like there are a bunch of problems being described in this thread.

I'm having the issue where the computer goes to sleep, and then goes into a completely unresponsive state where the screen is off, the sleep light is on (solid, not pulsing), and the fans are running. Completely unresponsive, only a hard reset gets it out of it.

I'm on an early 2008 MacBook Pro, 2.5GHz Core 2 Duo.

The 10.10.1 update did not fix it for me.

After all my work arounds, endless testing,and a final clean install, the problem

of the unresponsive "sleeping / wake status," in Yosemite persists! My Mac Mini

sill can't be taken out of it's deep sleep status unless I do a Restart.Everyday!

Grrrrrrrrr!

Unless Apple rectifies this asap there are going to be a lot of frustrated customers,

repeatedly shaking their heads and needlessly worrying that they may cause damage

to their Apple computers having to do a hard restart each time!

And who undoubtedly will be looking for some form of compensation or redress- if only to acknowledge

and possibly fix this perplexing problem-if their Mac's hard drive break from the repetitive hard booting.

Isn't it time someone stepped up to the plate...before they all get broken?

My laptop is driving a second monitor via thunderbolt->DVI. When it is sometimes woken from computer (not screen) sleep the aux monitor will show the desktop and cursor, but the primary desktop on the laptop monitor is black. I can move the cursor, but have no desktop access that I can see on the laptop. If I unplug the aux monitor, I briefly see the desktop on the main computer, but it goes dark after a second. This started with the 10.10.1 update.
