APPLIES TO:

SYMPTOMS

The symptoms may vary from Parallels Desktop installation/update failure to problems during its operation, like inability to load required drivers, create VM, etc.

CAUSE

Mac OS system failure or incorrect software update may result in inabilty to install Parallels Desktop or load system files properly. Working in Mac OS for long periods of time without restart may lead to some minor glitches to appear in the system as a whole.

RESOLUTION

To resolve these issues, do the following:

1. Reboot your Mac.

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

3. Select Macintosh HD on the left tab and click the Repair Disk Permissions button.

4. Launch the Uninstall Parallels Desktop application (you can find it on the Parallels Desktop CD or in the downloaded Parallels Desktop DMG package) and follow the on-screen instructions. Please note that Parallels Uninstaller does not remove virtual machines from your Macintosh hard disk. It is important to use the Uninstaller of the Parallels Desktop version currently installed or newer.

5. Launch Applications --> Utilities --> Terminal and type the following commands:

NOTE! Please be sure to enter the commands in the full form because in case of missing any Mac OS can be corrupted.

sudo rm -rf /Library/StartupItems/Parallels
sudo rm -rf /Applications/Parallels
sudo rm -rf /System/Library/Extensions/vmmain.kext
sudo rm -rf /System/Library/Extensions/hypervisor.kext
sudo rm -rf /System/Library/Extensions/Pvsvnic.kext
sudo rm -rf /System/Library/Extensions/ConnectUSB.kext
sudo rm -rf /System/Library/Extensions/Pvsnet.kext


If some commands are showing “No such file or dir” – it means that uninstaller deleted them already and this is normal.

6. Repeat steps 2 and 3.

7. Restart your computer again

8. Eject Parallels Desktop installation CD - if you performed uninstall process from CD.

9. Install Parallels Desktop for Mac.
