Cannot start Parallels Desktop after upgrade to Snow Leopard.

  • Parallels Desktop 5 for Mac Standard Edition
  • Parallels Desktop 4 for Mac Standard Edition


When you are trying to start Parallels Desktop application nothing happens, application is not responding or crashes.


This can be caused by incorrect, corrupted permissions to /usr/local/ directory in Mac OS X.
It can also be  the result of an upgrade to Snow Leopard or activity of third-party applications.


1. Open Terminal (Application -> Utilities-> Terminal)

2. Copy/paste command bellow and press Return

ls -ld /usr/local/

3) You may see the output similar to the one bellow:
drwxrwxr-x  6 root  wheel  204 Oct  9 20:30 /usr/local/

4) If you see other permissions, like: drwxr-xr-x (drwxr--r-x and etc), please use the following command to correct them:
sudo chmod -R 775 /usr/local/

Copy/paste it in Terminal and press Return.
You will be prompted to enter your administrator password.
You will not see it while typing.

After that please try to start Parallels Desktop again.
