I have macOS High Sierra ver 10.13.6 and use VmWare Fusion Version 8.5.10 since 2014. In the last month, I can't use VMWare because for this error :
Failed to open kernel extension "com.vmware.kext.vmci": No such file or directory
Please make sure that the kernel extension is loaded.
Module 'DevicePowerOn' power on failed.
Failed to start the virtual machine.
Help me with this. Thanks.!
Reinstall VMware Fusion and then go to the Security and Privacy tab of the System Preferences. You'll see that VMware Fusion is requesting access to part of your system which you need to authorise. Click the button and it should work.
