Hello,

I've been using parallels to run windows on my mac for school for the past few weeks and haven't had an issue until recently. For some reason whenever I start Parallels I get a black screen and can't seem to do anything. I'm using Mac OS Sierra Version 10.12.6. Does anyone have any idea how to fix this? Thanks
 
JohnR23, good luck getting a response from Parallels. In the end I downloaded a new versions of windows 10 and I am up and running, but all of the data that resides on the old version is lost until I can get a local IT professional to figure out how to get it to work.

Hello paula4, Do you have the old version working? did you installed Windows 10 as a second virtual machine inside Parallels Desktop?
 
I do not. I need a tech to go into the registry to pull all of the old data out. Parallels support is brutal. The people on the forum are much more intelligent and supportive.
 
I see the black screen and none of the restart/stop/reset tricks is working. I'm running Parallels 13.3.0 (43321) on Mac OS High Sierra 10.13.5 Beta. The client OS is Mac OS High Sierra 10.13.5 Beta (i.e. same OS as the host). The login screen is fine, and I log in, but then the screen goes black. Anything else to try?
 
I just downloaded parallels client on my MacBook Pro, but I keep getting a black screen. How do I reset it? The above mentioned link Maria sent is for Windows 10. Can you send me the one for the Macbook?
 
i have the black screen at first....tried the reset...tried every thing suggested...nothing...then someone said to add more memory usage...i went from 8 to 15 gb of memory on my machine and now the windows does not even start, yet get to to the black screen....now what...i would appreciate if someone from parallels calls to fix the problem...

Hello, could you change setting to the 2-4 GB p and check the issue please?
 
A file or device required for the operation of Hard Disk 1 does not exist or is used by another process, or you have no permission to access it. The virtual machine will continue running, but the device will be disconnected.
