    I've now been on the phone for (in total) over 4 hours with Apple. Bottomline: no solution.

     

    As in the meantime neither recovery partition nor web-recovery did work anymore (presumeably due to the high amount of unscheduled reboots) the guys from the support hotline suggested I should take the iMac Retina to a ACSP. They checked the machine but couldn't find ANY hardware issue nor software issue; they re-installed Yosemite and told me no error would have appeared. Took the machine home and reinstalled most important software - didn't see the error for a day or two and after that - reboot, unexpected.

     

    I'm seeing "GPU restart" errors and the aforementioned sleep wake failure. To me the machine definitely has some kind of problem that's not caused on my side as the system had been reinstalled, harddrive had been re-formatted and also all software is always up to date. Plus: Before reformatting the machine was restored from a Timemachine Backup; my old iMac worked perfectly fine, no reboots whatsoever!!

    Since November 2014 my Retina iMac (fully loaded, i7, 32GB ram, 1 GB SSD, AMD M295) crashes almost once a day after being left alone for an extended time (with or without sleep mode enabled).  My old 27 inch i7 iMac NEVER had an issues. I have learned NOT to leave any applications running without saving data.  I NEVER had to worry with my last iMac. I keep hoping the next update will fix the problem.....

    Interesting....I 've had the same problem with my (new in December) 2012 Mac Mini Server 2.3 GHZ i7 Quad, 16 GB RAM. I replaced the 5400 rpm boot drive with an OWC Extreme 256 SSD. For almost 6 weeks it has crashed upon extend sleep wakes and misc spinning wheels etc.

     

    Apple replaced the logic board, did a SSD  boot drive wipe, repartition and re- install of 10.10.2,  and OWC replaced the RAM.....to no avail. Still crashed.

     

    Last week I received an external 7200 self powered  drive from OWC. I cloned the SSD boot drive to it and have used it for the boot drive for the last three days. No instability so far.

     

    A couple of hours ago I booted with the internal SSD drive. Had a kernel panic after wake almost immediately.

     

    I intend to ask OWC for a replacement SSD on Monday.

    I've spent hours on the phone with Apple and two things seemed to have exactly this problem:

     

    Apparently both trackpad and keyboard woke up my iMac from sleep. I deactivated the checkbox within Bluetooth options that Bluetooth devices can end hibernation. As I'm also using a Logitech mouse that wasn't a problem.

     

    The other thing Apple suggested was following terminal command:

    sudo pmset -a autopoweroff 0


    SSince a week or so the iMac sleepw as expected and didn't crash once...

    So are you using a USB keyboard and mouse?

    No, I'm using original Apple Bluetooth Keyboard and Magic Trackpad plus a Logitech Wireless Mouse (using the unified receiver from Logitech). The "unified" receiver plugs into USB.

    I unchecked the wake-from-sleep option in bluetooth preferences and switched to a usb keyboard. However, the apple wireless mouse still wakes the 2012 Mac Mini Server.

    Sorry.....it took 3 restarts for the change to stick.

    Strange... I also noticed that this setting wasn't carried over to the other user accounts on the Mac. I had to deactivate the wake upon bluetooth devices for each and every user.

     

    But: Still no crashes or sudden restarts (knockonwood).

    After all the BS that I've been through; logic board replacement, RAM replacement, self powered external boot drive purchase, multiple re-installs of 10.10.2 and many days at Apple Store and an Apple Authorized Service dealer......it appears that it has all come down to the OWC SSD Boot Drive not liking  to be woken up by a Bluetooth device in 10.10.2.

    Having had the same problem on a macbook pro (late 2014) after installing Yosemite 10.10.2, but in particular after having changed 'energy saving' setting (system preferences). By removing "SystemsConfiguration" and resetting PRAM, according instructions from Darkkz (THXS !!), problem (i.e. system remains=freezes in 'sleep' mode, i.e. dark screen sometimes with visible cursor, despite attempts to wake the computer by pressing keys, touchpad or opening laptop screen )  was solved.

    Since this did not happen under Maverick, I do believe this appears a glitch in Yosemite in combination with screen save settings changes.

    So apparently the "sleep wake failure" on my retina iMac reappeared. Three unwanted reboots only today. No solution Apple had come up so far solved the problem. I hope I'm going to have another phonecall with them next week, but I really don't know what else than exchanging the whole machine could be done about this.

    Sent them all console logs for "sleep wake failure", maybe they can find out anything new here...

    Have you tried Darkkz's solution?  It worked for me (also see my post above).

    I believe the culprit is Yosemite and screen (saver) settings

    To expand on my solution for sleep wake failure/kernel panics in 10.10.2

     

    In System Preferences/Bluetooth I disabled 'Allow Bluetooth devices to wake this computer'.

     

    I replaced the wireless Apple Keyboard with an Apple USB keyboard so that I could wake the computer from sleep.

     

    It's been touble free since (7 days),

    Tried all of this. PRAM resets and so on. No solution.
