Set How Many Processors are Allocated to a Virtual Machine
You can change the number of virtual CPUs that will be used to handle the processes running in a virtual machine. Parallels Desktop automatically calculates the maximum allowable number of virtual CPU. The calculation is based on the number of physical CPUs available to your macOS computer.
To set how many processors are allocated to a virtual machine:
- Shut down the virtual machine.
- Open the Actions menu and choose Configure .
- Click Hardware > CPU & Memory and select a number from the Processors menu.
