Hi, I use Parallels 11 with Windows 10 on El Capitan on a MacBookPro and clamshell mode with external monitor. I used to use Parallels 10 before the upgrade, and there were high CPU usage and heating up issues. So I upgraded. Now, whenever I leave the my seat for an amount of time that has the computer go to sleep, when I return Windows(Parallels) has frozen again. Mac OS (El Capitan) running in the background is fine however. It's just Parallels that's constantly freezing up. Hence, my Parallels 11 crashes every time. I tried resetting the CPUs and RAM a few times. Tried uninstalling Parallels, then reinstalling it to no avail. Anybody else have this issue? Please help!
Hi, To improve Windows virtual machine follow this solution also check for updates whether you are running latest Parallels Desktop build and let us know how it works.
Hi dnlgyju, please follow the steps mentioned below to fix the issue 1. Download CPU throttle application to your Mac. 2. Move it to somewhere it can be kept for long period of time (like Documents). 3. Note: following lines should be typed without quotes. Go to the same location in Mac Terminal ('cd ~/Documents'). 4. Type in: 'chmod +x cputhrottle' 5. Go to 'Activity Monitor' and find the process you want to limit (in Parallels Desktop case - 'prl_vm_app'). Note its PID. 6. Back in Terminal, type in: 'sudo ./cputhrottle ' (example: 'sudo ./cputhrottle 766 70'). You may also need to enter Mac user's password into Terminal if it asks for it. 7. Application is now active. It is limiting the CPU consumption of virtual machine process and your CPU should no longer heat up as much. 8. You can stop running cputhrottle by pressing CTRL+C in Terminal. This will remove the limit on the process.
