iMac 27' 5k crashes after sleep, please help!

Dear All,

I have
-iMac Late 2014, 5k, i QC 3.5 with 24Gb RAM,1TB fusion drive and 2Gb Radeon.
-Latest version of Parallels 11 with Windows 10 running

My problem is then iMac goes to sleep with VM running it can't wake up, it simply crashes with grey screen. Only way to wake it up is full restart with pressing POWER button for >4sec.
Any advices are welcome since this problem is very much annoying!

Hi Marek, please try this solution.

 

Dear Dhruba,

thanks for the tip, I have tried it and it doesn't resolved the problem.

However, I've made some tests I see that my MAC is crushing only then it being left with VM running. I have reduced number of cores used by VM from 3 to 2 and RAM split is 50/50 (both systems get the same amount of RAM) but still after waking up from sleep I get grey-scale screen and after some attempts system just freezes.

Hope somebody can advice or help on this topic.

Cheers,
Marek

Did you solve this issue?
I have it since i have bought Parallels 11 for my iMac 27 late 2013. If i forgot to close the VM and the iMac goes in hibernation the day after i'm forced to reboot with the power button.
Some time ago i have contacted support and they told me to uninstall parallels, repair permissions e reinstall parallels but it seems that it didn't work

 

Hey LucaL1, Please check if your Mac OS X is updated (Click on Apple Logo > Software Update)
If yes, move the Windows PVM file to a different location on Mac and check how it goes.
