Like most of applications on a Mac, Parallels Desktop does not require uninstallation - simply move the application to Trash.
Note: Your virtual machines will not be affected by this procedure — only the Parallels Desktop application will be uninstalled. If you want to remove a virtual machine, please see KB 5029
Shut down your virtual machine and quit Parallels Desktop.
Open your Applications folder and drag the Parallels Desktop icon into the Trash.
Empty the Trash.
- Reboot your Mac.
