Parallels FullScreen Freezes Mac

I have been testing to see what issue is causing my iMac late 2014 27" to freeze every morning. This issue has been ongoing since I installed High Sierra. I had a support ticket open with Parallels and they said it's an Apple issue.

I have narrowed it down to the issue being with full screen. If I have full screen on my Windows 10 VM, it'll freeze the entire computer. I installed teamviewer on the mac side to see if I can access it, but when it freezes, the computer is not able to remoted into. This issue goes away when in Coherence mode, as I've been testing every other day to see if I can replicate. When I use Coherence mode, there are no issues, I just really don't like using it.

Has anyone else had these issues or something close to it? Did about all the troubleshooting I could with Parallels support.

 

I'm new to the forum and trying to figure out how to start a new thread. I am also having issues with Windows 7 freezes using Parallels 13 and Sierra. Any help on either?

But can you tell me how to start a new discussion thread here, please?

 

They said to reinstall parallels tools but windows is freezing up and preventing that. I posted that response but no response from support. I'd like to start a new thread here and get forum help. If you can facilitate that, I'd be grateful

 

Once you logged in you can see an option which says " New threads " on the top right corner.

I am having a Mac freeze problem with Parallels. Working with MAC without starting my Windows 10 VM runs smoothly for days with no problem. When starting the Windows 10 VM and run some office applications like Outlook or Excel makes the temperature on the processor going high up to 220F making the cooler run full speed. After a few minutes like this the whole computer hangs and freezes. Little color turning disc starts on Mac and it is impossible to continue without pressing on/off button and restart my mac. My config is MacBook Pro 13" Retina 3,1GHz i7, 16GB RAM, 1TB SSD, running on macOS High Sierra V 10.13.4 and running parallels 13 with Windows 10 and office 365.
I have streamlined the most I could but from now on I need some professional help. Thanks!
