Option | Description |

Mouse | If you play games in a virtual machine, the Mouse menu allows you to set how to use a mouse:
|
Mouse pointer sticks at window edges | When working with a virtual machine in Window view mode, you may often need to move the mouse pointer to the edges of the virtual machine window to display various guest OS items: for example, to display the Start menu in Windows 8, hidden taskbar in Windows XP, or macOS menu bar when any of the guest macOS applications is running in full screen. The Mouse pointer sticks at window edges option makes the mouse pointer pause for a while at the edges of the virtual machine window and you won't move the mouse outside of the virtual machine window by mistake. To move past the edge, just move the mouse quickly. |
Keyboard | Choose Optimize for games from the Keyboard menu if you actively use the modifier keys Option (Alt), Ctrl, and Shift in action games. When this option is selected, signals from these keys are processed immediately. |
Mitigating Scrolling Issues in Linux
Linux virtual machines on both Intel and Apple Silicon Macs have been known to have occasional issues with scrolling sensitivity, where a mouse pointer may start to behave erratically when using a trackpad for scrolling. If you encounter such a problem, you may adjust the scrolling sensitivity to your liking by executing the following command in macOS Terminal:
$ defaults write "com.parallels.Parallels Desktop" "HID Host Hook.Scroll Sensitivity" X
where X is the inverse scrolling sensitivity value. The default one is 20, and the maximum is 120. Make note that 120 means the lowest possible sensitivity. With the value set to 120, you would need to work the trackpad very energetically to scroll in the Linux VM.
Note: This command only works in Parallels Desktop for Mac 19.3 or newer and affects the scrolling sensitivity only in virtual machines, not your main macOS system.
