By Junaid, maker of Taskglass · Last reviewed

Parallels Desktop, which runs Windows or other operating systems in virtual machines.

Parallels Desktop runs virtual machines on your Mac. prl_vm_app is a running virtual machine, prl_disp_service is the background service that manages VMs, and prl_client_app is the Parallels interface. A running VM's CPU and memory reflect everything happening inside Windows or the other guest system.

Why is Parallels Desktop using so much CPU or memory?

  • A virtual machine running, especially Windows updates or antivirus scans inside it
  • Large memory assigned to the VM
  • Games or heavy apps inside the VM

What to do

  1. 1Check what's running inside the VM (for example Windows Task Manager)
  2. 2Suspend or shut down VMs you aren't using
  3. 3Lower the VM's CPU and memory in its configuration
  4. 4Keep Parallels Desktop and its Tools updated

Safe to quit? With care.

Force quitting prl_vm_app is like pulling the plug on that VM; shut it down or suspend it from Parallels instead.
