Mouse/Trackpad optimizations in a virtual machine

Information

Parallels Desktop provides functionality allowing you to control how a pointer input, from a mouse or a trackpad, is captured and processed by the virtual machine. 

For this functionality to work, Parallels Tools must be installed in your virtual machine.

To get to these options, simply open virtual machine's Configuration and go to Hardware > Mouse & Keyboard > Mouse.

The options you will find there are as follows:

Scrolling

Inertia Scrolling.

When using scrolling in a virtual machine, the input device doesn't operate directly in the virtual machine. Instead, Parallels Desktop captures the scrolling events on the Mac side, and sends them to the virtual machine. Since the virtual machine cannot identify what is the cause of this or that scrolling event (the use of scrolling with inertia or scrolling without inertia), there is no way to disable inertia scrolling in the virtual machine if it is enabled on the Mac side.

To disable inertia scrolling on the Mac, please perform the following steps:

  1. In the top left corner, click the Apple icon > System Preferences > Accessibility 

  2. On the left pane, locate and click Pointer Control and click Mouse Options… (Trackpad Options…).

  3. In Scrolling select without inertia and click OK.
