Freezing or Screen Going Black

H

HomeR2

Bit poster
I mostly have parallels running in the background and infrequently (maybe a few times a day) need to log in and do something that is Windows-related (win 7).
In between those times I often find that parallels has frozen or the screen is completely black. I have to reboot my mac in order to get it to reset.

Is there some patch I can apply? If not then is there an error log somewhere I should be looking at?

If I need to reinstall Parallels, could someone instruct me how to backup/restore my Windows image? I have quite a setup that would take days to rebuild.

Please let us know the versions of Parallels Desktop and Mac OS X to investigate further.
 
I am running parallels 11 with windows 10 and after update I am getting a black screen and am not able to access changes in my virtual machine to change the graphic memory size....please help! I don't want to pay for the parallels 12 upgrade
 
Hello JanM2, please shut down your Windows 10 virtual machine and go to Parallels Desktop icon (two red line on Mac menu bar) and choose Control Panel, select Windows 10 configuration-> Hardware-> Graphics and resize the memory. Please check out this article to know more information.
