The symptoms may vary. It may be a failure when you install/update Parallels Desktop or problems during operation, such as the inability to create a VM, etc.

Resolution

To resolve these problems, please follow the steps below:

1. Reboot your Mac.

NOTE: Please print these instructions from File ► Print browser menu for your convenience

2. Launch Applications -> Utilities -> Disk Utility.

3. Select Macintosh HD on the left panel and click Repair Disk permissions.

4. Launch the Parallels Desktop
Uninstall (for this purpose you can use Parallels Desktop Installation CD or .dmg package downloaded from Parallels web site) and follow the instructions on the screen. Please note that the uninstall program does not remove Parallels virtual machines from your Macintosh HD. It is important to use the uninstaller for the currently installed version of Parallels Desktop, or the most recent one.

5. Launch Applications ->
Utilities -> Terminal and copy/paste the following commands:

NOTE! Please make sure you enter commands in complete form, because in case of improper usage, Mac OS might be corrupted.

cd /Library/StartupItems/
sudo rm -rf Parallels
cd

sudo rm -rf vmmain.kext
sudo rm -rf hypervisor.kext
sudo rm -rf Pvsvnic.kext
sudo rm -rf ConnectUSB.kext
sudo rm -rf Pvsnet.kext


It is normal, if commands will result in "No such file or dir" output - it means that the uninstaller has already removed the files listed.

7. Restart your Mac computer.

8. Eject
Parallels Desktop installation CD if you ran the uninstall process from the CD.
