How do I change Parallels settings if the virtual machine won't start?

Question

macOS

Good afternoon! It so happened that I had to downgrade on an older mac. All data has been migrated by Time Machine. But unfortunately the windows image in Parallels won't start, blaming that my mac doesn't have enough "processors". In this configuration, only 2 are available to him, and before that there were 4. And in the settings of the virtual machine, you cannot change anything until it is completely stopped. Question: How to fix the configuration of the virtual machine to still run windows.

Answer 1

Stop through the menu and that's it.
