Hello everyone. I have similar problem with el capitan and Parallels 8. Networking module and USB don't work. Do you have any suggestions / command line commands to solve both issues ?
El capitan is very unstable on my Mac Book Pro 13' Retina. Hangs up a few times a day and restart automatically.
I was trying to install Trial version of Parallels 11 but it removes my Parallels 8 app (it doesn't matter what was the application folder name - different from Parallels Dekstop.app)
I have executed following commands:
$ cd /Applications/Parallels Desktop.app/Contents/Library/Extensions/10.6
$ sudo kextutil prl_hypervisor.kext
Diagnostics for prl_hypervisor.kext:

It seems that almost nothing works correctly in el capitan .
Do someone know how to add untrusted kext module to hash exception list ?
