I was able to use Parallels just fine this morning. I then changed the network adapter settings to "Shared Network", it was on Default Adapter. After that, Parallels completely crashed and so did OSX. Now every time I launch parallels, OSX crashes and restarts. Kernel Panic log below. PLEASE HELP!

Hi FRANKC3, Please perform the below steps & check how it works. * Uninstall Parallels Desktop using PDremove.app : Refer this link * Open Disk utility from Mac application folder > Select your MacintoshHD on the left side of the window, select "First Aid" tab on the right side. * After this is complete, close Disk Utility and restart you Mac computer. * Reinstall latest version of Parallels Desktop : Refer this link If the issue still persist, kindly post us the problem report ID number, we will be happy to check it for you. Thanks, Dhana.
Same issue, your steps DO NOT WORK. And it is impossible to generate a problem ID since if I am connected to internet parrallels causes immediate kernal panic on start up logo with spinning thingy...any other suggestions?
