Optimization Settings

Using Optimization settings, you can limit the virtual machine resource usage.

Note: The Optimization pane is available in Parallels Desktop for Mac Pro and Business Editions only.

To access Optimization settings:

  1. Do one of the following:
    • Click the Parallels icon in the menu bar and choose Configure.
    • If the Parallels Desktop menu bar is visible at the top of the screen, choose Actions > Configure.
  2. Click Options and select Optimization.


If your Mac lacks resources for running two or more virtual machines at a time, you can limit the virtual machine resource usage for the virtual machine doing more important work to have more resources. Drag the slider between Low, Medium, and No limit points. If you change this setting and then don't like how Windows is performing, then try a different setting.
