Cause of this kernel panic IOVideoPocketCamDevice::terminate
Seems /Library/Extensions/IOVideoPocketCam.kext hasn't been updated for High Sierra. Remove this kext and reboot the machine.


Boot into Safe Mode (hold ⇧ whilst turning Mac on until Apple logo) and log in as usual.
Safe Mode disables all third-party extensions so this problematic kext won't be loaded.
Open Finder, press ⇧⌘G and enter /Library/Extensions.
Find IOVideoPocketCam.kext and delete the file (move to Trash).
Reboot as normal.
