JochiePiet Posted November 28, 2019 Share Posted November 28, 2019 (edited) Hi, I have upgraded from Mojave to Catalina 10.15.1. It went almost flawlessly. The only issue is the computer not waking up from sleep. Just a grey screen. Hard reset is required. Of course I have been searching the Internet but to no avail. The sleep-awake cycle did work on Mojave. I have noted that it is now impossible to boot in save mode. Trying to do so produces the message: " error loading kernel (0xe)" . Since I use Clover I have tried the bootflags -f en UseCache=no (in addition to -v en -x) . I wonder if the last one is a Clover bootflag? Here are my specs: Motherboard Gigabyte GA H77 D3H rev 2.0 MacOS Catalina Version 10.15.1 (Build 19B88) Kernel Darwin 19.0.0 x86_64 RAM 4.00 GB Model Identifier iMac14,2 CPU Intel(R) Core(TM) i3-3225 CPU @ 3.30GHz Intel Generation Ivy Bridge Any help is of course much appreciated! config.plist Edited November 28, 2019 by JochiePiet More info Link to comment Share on other sites More sharing options...
JochiePiet Posted November 28, 2019 Author Share Posted November 28, 2019 (edited) 18 minutes ago, Hervé said: Sounds like Catalina is set for hibernation (OS X/macOS default mode) and, after going to sleep, it tries to wake from an image, something that was always poorly supported on Hackintosh. Check your hibernation status: pmset -g If applicable, try and revert to plain old sleep and delete any sleep image file that may exist: sudo pmset -a hibernatemode 0 sudo pmset -a hibernatefile /dev/null sudo rm -fv /var/vm/sleepimage Thank you for your answer. here is the output of pmset -q: System-wide power settings: Currently in use: hibernatemode 0 womp 1 networkoversleep 0 sleep 15 (sleep prevented by mds_stores) Sleep On Power Button 1 ttyskeepawake 1 hibernatefile /var/vm/sleepimage disksleep 10 displaysleep 10 So to me this looks all-right. Although I do not get the phrase " sleep prevented by mds_stores". Looked for it on the Internet. Seems to be connected to Spotlight. My system seems to go to sleep so I still do not get it. I have checked /var/vm: no sleepimage. Edited November 28, 2019 by JochiePiet more info Link to comment Share on other sites More sharing options...
