If Parallels does not start (Make sure that the prl_disp_service is active)

If you want to start Parallels and you get the following error message:

"Unable to connect to Parallels Service.
Make sure that the prl_disp_service process is active and it is not blocked by Firewall. For details, please refer to http://kb.parallels.com/en/8089. If the problem persists, contact the Parallels support team for assistance."

no need to worry. All you need to do is open Terminal, stop and restart Parallels:

sudo launchctl stop com.parallels.desktop.launchdaemon

Then restart it:

sudo launchctl start com.parallels.desktop.launchdaemon

If you run the following command now:

sudo launchctl list | grep com.parallels.desktop.launchdaemon

The output should be something like this:

94248 - com.parallels.desktop.launchdaemon

Try again, should be okay now.


  1. nope. com.parallels.desktop.launchdaemon still is running after telling it to start. what is next?
