Unable to connect to Parallels Service.

Hello, i have a trouble:


Unable to connect to Parallels Service.

Make sure that prl_disp_service is running or check your firewall settings. If the problem persists, contact the Parallels support team for assistance.


I read this posts, but it useless to me.

One of this commands helps till the moment of reboot of system:
1) sudo chmod 644 /Library/LaunchDaemons/com.parallels.desktop.launchdaemon.plist
2) sudo chown root:wheel /Library/LaunchDaemons/com.parallels.desktop.launchdaemon.plist
3) sudo launchctl load /Library/LaunchDaemons/com.parallels.desktop.launchdaemon.plist
4) sudo launchctl start com.parallels.desktop.launchdaemon - i think it help temporary

And this is very inconvenient to do this every time.


-bash: /Library/Logs/parallels.log: Permission denied


Thank you!
