Ubuntu VM and El Capitan VM lock up on MacBook Pro early 2011

I'm using the latest version of Parallels Desktop and just started having a problem with using VMs like El Capitan and Ubuntu. I haven't tried my Windows 10 VM for concern that I will have the same problem.

The VM screens split and lock up, then the Mac reboots.

Is anyone else having this problem? Are there any fixes available?

 

Hi @JosephM5 , please help us with the screenshots, we will check and assist you further.

 

Hello, and thanks for responding to my message.

I deleted both the El Capitan and Ubuntu VMs and re-installed them. So far, I haven't had any problems, although the El Capitan VM seems to make the Mac fan work harder. I also have a Windows 10 VM that I haven't used since my previous issues so I'll run that now and let you know the outcome.

Thanks again for your quick response.

 

@JosephM5 Please keep us posted with regards to the issue.

 

Hello, I started up Parallels Desktop today to use the El Capitan VM. I didn't get to log into the VM - my MacBook Pro just shut down and reboot.

After the reboot, I received the message displayed in the screenshot about Operation Timeout
